The Needle Myth: Does a Thinner Needle Really Damage Blood During Collection?

If you've spent any time around phlebotomy or blood collection, you've probably heard the rule: "Bigger needle, safer blood. Thin needles burst the cells." It's repeated in training rooms, passed between collectors, and rarely questioned.

But what does the actual peer-reviewed research say? The answer might surprise you — and it has very little to do with the needle's size.

What "Damage" Really Means Here
When red blood cells rupture during or after a draw, it's called hemolysis. It releases hemoglobin and other cell contents into the surrounding plasma or serum, which can throw off lab results; sometimes badly enough that the whole sample has to be redrawn. So when collectors worry about "cell damage," hemolysis is almost always what they mean.

The question is: what actually causes it?

The Needle Gauge Story Is More Complicated Than You'd Think
Older studies did report a link between very fine needles and higher hemolysis. But here's the twist; newer needle designs have essentially erased that gap. A 2024 study testing a redesigned 25-gauge blood collection set (with an ultra-thin wall and a smoother bore) found it did not increase hemolysis compared to standard, larger needles. A separate pediatric study comparing 21/23G needles against 23/25G needles found the same thing: hemolysis was not significantly different between the sets, even though the thinner needles caused noticeably less pain. And in an oncology population, the smaller-gauge set actually produced less hemolysis than the larger one.

So the modern picture is this: a well-designed thin needle, used properly, does not automatically damage blood. The old "small gauge = damaged cells" warning was built on older needle technology; much of it no longer applies.

The Real Culprit: How the Blood Is Pulled, Not What It's Pulled Through
Here's where the story gets genuinely interesting. Across multiple studies, the strongest predictor of hemolysis wasn't needle size; it was how aggressively the blood was drawn out.

Studies comparing vacuum-tube collection versus gentle syringe aspiration found vacuum draws produced significantly more hemolyzed samples — in one emergency department study, 24% of vacuum-drawn samples were hemolyzed versus 16% with syringe draws.
The mechanism is exactly what you'd guess: vacuum tubes pull blood at a fixed, often forceful pressure, creating turbulent flow and high shear forces on red blood cells as they're yanked through the needle. A slow, controlled hand on a plunger lets the collector ease off when resistance increases; something a vacuum tube simply cannot do.
This effect is dramatically amplified when drawing from an IV catheter rather than a vein directly. One classic study found hemolysis rates climbing as the catheter got narrower and the draw stayed fast; reaching up to 100% hemolysis in the smallest catheters under standard vacuum pressure. But when researchers slowed the draw down and lowered the pulling force, even narrow access points performed dramatically better.

In short: it's the pressure and speed, not the millimeters of needle width, that decide whether the red blood cell survives the trip.

Why This Makes Biological Sense
A red blood cell is a flexible little sac of hemoglobin wrapped in a thin membrane. It can squeeze through spaces narrower than itself without trouble; that's literally what it's built to do, since it does this every day moving through capillaries far smaller than any needle. What it can't tolerate well is being suddenly accelerated and decelerated, or dragged through a stretch of turbulent, high-pressure flow. That kind of mechanical whiplash, not the bore of the needle, is what tears the membrane.

What This Means in Practice

For anyone collecting blood; whether for clinical testing, donation, or research purposes: here's the practical bottom line drawn directly from the evidence:

Don't assume a thinner needle ruins the sample. With modern needle designs, 23G and 25G needles perform comparably to standard 21G needles in hemolysis rates, while causing noticeably less pain.
Slow down the draw, especially through small or difficult veins. Forceful, rapid aspiration — not needle width — is the factor most consistently linked to hemolysis across studies.
Be extra cautious with IV catheter draws. Hemolysis risk rises sharply when blood is pulled from a catheter under vacuum, especially through narrow catheters. Manual, gentler aspiration meaningfully reduces this risk.
Vacuum pressure matters more than most people realize. Where possible, using lower-vacuum tubes or controlled aspiration methods reduces hemolysis compared to standard vacuum draws.
Technique trumps equipment. A skilled, patient collector using a small needle will very often get a cleaner sample than a rushed draw through a large one.

Conclusion
The idea that small-gauge needles inherently damage blood cells is largely outdated. Modern needle design has closed that gap, and the research consistently points elsewhere: it's the speed and pressure of the draw ;not the size of the opening, that puts red blood cells at risk. Next time someone insists on a bigger needle "for the cells' sake," the more useful advice might simply be: slow down.

WHAT IS PLASMA and why is it called “Liquid Gold”?

June 10, 2026
Imagine a substance so powerful that a single litre of it can be turned into life-saving medicines for dozens of patients. A substance so complex that scientists have spent eight decades trying to fully decode it. A substance so scarce — and so vital — that it is bought and sold for more per litre than many precious metals.

That substance is not a pharmaceutical invention. It is blood plasma: the golden liquid that carries your blood cells, feeds your tissues, protects you from infection, and stops you bleeding to death when you are wounded. And it is, quite literally, irreplaceable.

This blog explores the science of plasma in full — what it is, what it does inside the body, how it becomes medicine, and why the world is running out of it.

1. Blood Is Not Just Red

Most people picture blood as a uniformly red fluid. In reality, blood is a complex connective tissue made of four distinct components — and only one of them is responsible for that vivid colour.

Lets learn about the Four Components of Blood :

Red blood cells (erythrocytes): carry oxygen via haemoglobin — responsible for the red colour.
White blood cells (leukocytes): the soldiers of the immune system.
Platelets (thrombocytes): tiny cell fragments that plug wounds and initiate clotting.
Plasma: the liquid matrix in which everything else is suspended. It makes up 55–60% of total blood volume.

Spin a tube of blood in a centrifuge for a few minutes and the heavier cells sink to the bottom. Above them sits a thin, pale layer of white cells and platelets (the “buffy coat”). Above that — taking up more than half the tube — is plasma: a translucent, amber-gold fluid that looks almost unremarkable. Looks can be deeply deceiving.

If you have ever had blood drawn and noticed the sample separate in the collection tube, the pale yellow layer you saw at the top was plasma. That golden liquid is doing far more work in your body than the red part that catches the eye.

2. The Biochemistry of Plasma: What’s Actually in That Golden Fluid?

Plasma is approximately 90–92% water — but the remaining 8–10% is one of the most complex mixtures in all of biology. Scientists have identified more than 700 distinct proteins in plasma, along with dissolved gases, electrolytes, lipids, glucose, hormones, enzymes, and metabolic waste products. Each plays a role. None is there by accident.

2.1 Plasma Proteins: The True Stars of the Show

Plasma proteins are present at a concentration of 6–8 grams per decilitre of plasma. They are the source of virtually all plasma-derived medicines. The three principal families are albumin, globulins, and fibrinogen.

2.1.1 Albumin (60–65% of plasma proteins)

Albumin is synthesised exclusively in the liver at a rate of roughly 10–15 grams per day. It is the most abundant protein in plasma and one of the hardest-working. Its primary physiological role is maintaining colloid osmotic pressure — the force that keeps fluid inside your blood vessels rather than leaking into your tissues. Without adequate albumin, fluid accumulates in the tissues, producing the characteristic swelling (oedema) seen in liver failure, malnutrition, and nephrotic syndrome.

Beyond osmotic regulation, albumin is a versatile molecular taxi. It binds and transports fatty acids, bilirubin, calcium, thyroid hormones, cortisol, and more than 400 drugs. Its remarkable binding capacity is why albumin infusions are used clinically in conditions ranging from hypovolaemic shock and burns to hepatic encephalopathy and spontaneous bacterial peritonitis.

Did You Know?

Albumin has a serum half-life of approximately 19–21 days. This means that the albumin circulating in your blood today was made by your liver nearly three weeks ago. Measuring albumin levels is one of the most sensitive indicators of chronic liver function and nutritional status.

2.1.2 Globulins (35–38% of plasma proteins)

The globulin fraction encompasses a heterogeneous family of proteins classified by their electrophoretic mobility into alpha-1, alpha-2, beta, and gamma groups. The most therapeutically significant are the gamma globulins — better known as immunoglobulins (antibodies).

Five classes of immunoglobulin exist in plasma: IgG (the most abundant, providing long-term immune memory), IgA (protecting mucosal surfaces), IgM (the first responder to new infections), IgE (involved in allergy and antiparasitic defence), and IgD (a B-cell signalling molecule). Individuals born with primary immunodeficiency disorders — such as Common Variable Immunodeficiency (CVID) or X-linked agammaglobulinaemia — cannot produce adequate immunoglobulins and suffer life-threatening recurrent infections as a result. For these patients, regular infusions of intravenous immunoglobulin (IVIG) sourced from pooled plasma donations are not a treatment option — they are a survival requirement.

Did You Know?

If you or a family member receives IVIG infusions, you are receiving antibodies collected from thousands of different plasma donors and concentrated into a single vial. Each infusion contains the combined immune memory of a crowd of strangers, all working to protect you. That is not metaphor — it is the literal mechanism of the therapy.

2.1.3Fibrinogen and the Coagulation Factors

Fibrinogen is the precursor to fibrin — the structural protein that forms the mesh of a blood clot. When vascular injury occurs, the coagulation cascade is activated: a precisely orchestrated sequence of enzymatic reactions culminating in the conversion of fibrinogen to fibrin by the enzyme thrombin. The fibrin mesh traps platelets and red cells, sealing the wound.

Also circulating in plasma at low but critical concentrations are the numbered coagulation factors: Factor VIII (deficient in Haemophilia A), Factor IX (deficient in Haemophilia B), von Willebrand Factor, Protein C, Protein S, antithrombin, and others. A hereditary deficiency in any one of these can result in a potentially fatal bleeding disorder, treatable with plasma-derived concentrates.

Did You Know?

It takes approximately 1,200 individual plasma donations to manufacture a single batch of Factor VIII concentrate sufficient to treat one severe Haemophilia A patient for a year. This extraordinary pooling requirement is one reason plasma-derived medicines are among the most expensive therapeutics in the world.

2.2 Electrolytes: The Conductors of Life’s Orchestra

Dissolved within plasma is a precisely regulated concentration of electrolytes — ions that carry electrical charge and govern fundamental physiological processes. Key plasma electrolytes and their normal ranges include Sodium (Na⁺) at 135–145 mEq/L (regulates fluid distribution and nerve function), Potassium (K⁺) at 3.5–5.0 mEq/L (critical for cardiac and muscle function), Calcium (Ca²⁺) at 8.5–10.5 mg/dL (muscle contraction, nerve transmission, and coagulation), Magnesium (Mg²⁺) at 1.7–2.2 mg/dL (enzyme co-factor and cardiac rhythm), Bicarbonate (HCO₃⁻) at 22–29 mEq/L (primary buffer for acid-base balance), and Chloride (Cl⁻) at 96–106 mEq/L (maintains electrochemical neutrality). Even small deviations from these ranges are clinically significant. Severe hyperkalaemia (excess potassium) can cause fatal ventricular arrhythmia. Severe hyponatraemia (low sodium) can cause cerebral oedema and seizures.

2.3 Nutrients, Hormones, and Waste

Plasma also transports glucose (the body’s primary fuel substrate, maintained at 70–100 mg/dL in the fasting state), amino acids, lipids packaged as lipoproteins (LDL, HDL, VLDL, chylomicrons), vitamins, and trace minerals. Simultaneously, plasma is the medium through which metabolic waste — urea, creatinine, uric acid, carbon dioxide — is carried to the kidneys and lungs for excretion. Hormones including insulin, cortisol, thyroid hormones (T3, T4), oestrogen, testosterone, and growth hormone circulate in plasma, often bound to carrier proteins, enabling endocrine signalling across vast distances in the body.

3. What Plasma Does Inside Your Body

Function 1: Transport

Plasma is the river along which everything in the body travels. Every molecule of oxygen absorbed in the lungs, every glucose molecule absorbed from the gut, every hormone secreted by an endocrine gland, and every waste product produced by a working cell is carried by plasma to where it needs to go. Without plasma, cellular communication and metabolic exchange would be impossible.

Function 2: Haemostasis (Stopping Bleeding)

The coagulation system embedded in plasma is one of nature’s most elegant engineering achievements. In response to vascular injury, two converging pathways — the intrinsic (contact activation) pathway and the extrinsic (tissue factor) pathway — activate a cascade of plasma-borne enzymes that culminates in the generation of thrombin, which converts fibrinogen to fibrin, forming a clot that seals the wound within minutes. Simultaneously, plasma contains natural anticoagulants (antithrombin, Protein C, Protein S) that prevent clotting from spreading beyond the injury site. This balance between pro- and anti-coagulant forces is one of the most finely tuned systems in human physiology.

Function 3: Immune Defence

The immune components of plasma constitute a multi-layered defence architecture. The complement system — more than 30 interacting proteins circulating in plasma — can directly kill pathogens via membrane attack complexes, tag them for destruction (opsonisation), and recruit immune cells to sites of infection (chemotaxis). Immunoglobulins neutralise viruses and bacteria. Acute-phase reactants such as C-reactive protein (CRP), fibronectin, and serum amyloid A rise dramatically during infection, facilitating pathogen recognition and clearance. Cytokines and chemokines dissolved in plasma coordinate the entire immune response.

Function 4: Osmotic Regulation (Fluid Balance)

Plasma proteins, primarily albumin, generate a colloid osmotic (oncotic) pressure of approximately 25–28 mmHg that opposes the outward hydrostatic pressure of the heart’s pumping action. This balance keeps fluid inside the capillaries rather than leaking into surrounding tissues. When plasma protein levels fall — as in liver cirrhosis (reduced albumin synthesis), nephrotic syndrome (urinary albumin loss), or severe protein malnutrition — oncotic pressure drops, fluid accumulates in the tissues, and oedema results.

Function 5: Acid-Base Balance

Human physiology demands that blood pH remain between 7.35 and 7.45. Deviations beyond this narrow corridor disrupt enzyme function, ion channel behaviour, and oxygen delivery. Plasma maintains this balance through three buffer systems working in concert: the bicarbonate–carbonic acid system (the dominant buffer, regulated by the kidneys and lungs), plasma proteins (which accept or donate protons as required), and the phosphate buffer system. The elegance of this system is that the lungs and kidneys can independently adjust their contributions in real time, providing both rapid and sustained buffering capacity.

Function 6: Heat Distribution

Plasma is an efficient carrier of thermal energy. Metabolic heat generated in the liver, working muscles, and other metabolically active organs is distributed by circulating plasma to the skin surface, where it is dissipated. This convective heat transfer is central to the maintenance of core body temperature within the physiologically optimal range of 36.5–37.5°C.

4. Why Is Plasma Called “Liquid Gold”?

The nickname has two dimensions: one visual, one economic and moral.

Visually, plasma’s golden amber colour comes from bilirubin (a haemoglobin breakdown product), carotenoids from diet, and other dissolved pigments. It does, quite literally, look like liquid gold when held up to light.

But the name has stuck because of something far more significant than colour.

4.1 The Medicines That Come Only From Plasma

A class of medicines called plasma-derived medicinal products (PDMPs) can currently be made in no other way. Unlike small-molecule drugs that can be chemically synthesised, the complex three-dimensional proteins in plasma cannot (in most cases) be perfectly replicated by a factory. They must come from human donors. The major PDMPs and the conditions they treat are:

Intravenous and Subcutaneous Immunoglobulin (IVIG/SCIG): Primary immunodeficiency disorders, autoimmune neuropathies (Guillain–Barré syndrome, CIDP), Kawasaki disease, immune thrombocytopenic purpura (ITP), and over 150 other conditions.

Factor VIII and Factor IX concentrates: Haemophilia A and B, respectively.

Albumin: Liver failure, burns, hypovolaemic shock, and sepsis management.

Alpha-1 Antitrypsin (AAT): Genetic emphysema (Alpha-1 Antitrypsin Deficiency), now being studied in cystic fibrosis and COVID-19.

C1-Esterase Inhibitor (C1-INH): Hereditary angioedema (HAE), a condition causing potentially fatal episodes of tissue swelling.

Fibrinogen concentrate: Major haemorrhage and congenital afibrinogenaemia.

Antithrombin III: Hereditary antithrombin deficiency and thromboembolism prevention in surgery.

Fresh Frozen Plasma (FFP): Emergency coagulopathy, disseminated intravascular coagulation (DIC), and trauma resuscitation.

Did you know?

If you receive any of these therapies, you are receiving a medicine that exists only because thousands of human beings voluntarily (or compensated) donated their plasma. There is no synthetic substitute for most of these products. Your treatment is built on human generosity — or, depending on where the plasma was collected, on an economic exchange that raises its own ethical questions.

4.2 The Global Plasma Economy

The global market for plasma-derived medicines exceeded USD 45 billion in 2024 and is projected to surpass USD 65 billion by 2030. The United States supplies approximately 70% of the world’s source plasma — a dominance rooted in U.S. regulations that permit paid plasma donation. Donors in the U.S. can be compensated between USD 30 and USD 150 per session, and may donate up to twice per week. Most of Europe, Canada, and Australia operate on a voluntary, unremunerated donation model, which produces far less supply. The result is that countries that prohibit paid donation are often entirely dependent on commercially sourced U.S. plasma for their national PDMP supply — an uncomfortable irony that has generated considerable policy debate.

Did You Know?

Globally, approximately 60 million litres of plasma are collected annually for fractionation into medicines. Demand is projected to require over 80 million litres by 2030. The gap between what the world needs and what donors currently provide is one of modern medicine’s most urgent supply challenges.

Conclusion

Blood plasma is, without exaggeration, one of the most scientifically extraordinary and medically indispensable substances known to human biology. It sustains life through transport, immunity, haemostasis, and homeostasis. It saves lives through the plasma-derived medicines that allow millions of patients with rare and chronic diseases to live with dignity. And it is shaping the future of medicine through liquid biopsy diagnostics, anti-ageing research, and emerging biotherapeutics.

The name “liquid gold” is earned on every level: in the amber gleam of the fluid itself; in the extraordinary biological value packed into every millilitre; in the clinical gold standard it represents for patients with no other options; and in the billions of dollars that flow around the global plasma economy. It is also earned, most importantly, in the quiet generosity of the donors — paid or volunteer, known or anonymous — whose veins supply the raw material from which lives are extended and healed.

If you receive a plasma-derived therapy, you are part of a remarkable human chain: from donor, to donation centre, to fractionation facility, to pharmacist, to you. That chain exists because science, medicine, and human generosity have worked together to make it possible. You are not just a recipient of treatment. You are the reason the chain exists.

WHAT IS PLASMA and why is it called “Liquid Gold”? Imagine a substance so powerful that a single litre of it can be turned into life-saving medicines for dozens of patients. A substance so complex that scientists have spent eight decades trying to fully decode it.

Every two seconds, someone in the world needs a blood transfusion. Knowing blood type compatibility is not academic — it is the difference between life and death."

रगतको रातो कोषिका (RBC): तपाईंको शरीरलाई जीवित राख्ने अदृश्य नायक

के तपाईंलाई कहिल्यै यस्तो लागेको छ कि शरीर धेरै थाकेको छ, काम गर्न जाँगर छैन, सास छिट्टै फुल्छ वा बारम्बार चक्कर लाग्छ?

धेरै नेपालीहरूले यस्ता लक्षणलाई सामान्य थकान, उमेर बढ्दै गएको प्रभाव वा कामको बोझ ठान्छन्। तर वास्तवमा यसको कारण हाम्रो रगतभित्र लुकेको हुन सक्छ।
हाम्रो शरीरमा रहेका "रातो रक्तकोषिका" (Red Blood Cells - RBC) जीवनका लागि अत्यन्त आवश्यक कोषिका हुन्। यी साना कोषिकाहरूले फोक्सोबाट अक्सिजन लिएर शरीरका हरेक अंग, मांसपेशी र कोषिकासम्म पुर्‍याउँछन्। साथै शरीरले उत्पादन गरेको कार्बन डाइअक्साइडलाई फोक्सोसम्म फर्काएर बाहिर निकाल्न मद्दत गर्छन्।
हामी सास फेर्न सक्छौं, हिँड्न सक्छौं, सोच्न सक्छौं र दैनिक काम गर्न सक्छौं भने त्यसमा रातो रक्तकोषिकाको ठूलो भूमिका हुन्छ।
म एक Medical Scientist रूपमा दैनिक रूपमा रगतका नमुनाहरू परीक्षण गर्छु। धेरै रोगहरूको प्रारम्भिक संकेत यही रातो रक्तकोषिकामा देखिन्छ। त्यसैले यी कोषिकाहरूको बारेमा सामान्य जानकारी प्रत्येक व्यक्तिलाई हुनु आवश्यक छ।

रातो रक्तकोषिका (RBC) भनेको के हो?
रातो रक्तकोषिका, जसलाई वैज्ञानिक भाषामा "एरिथ्रोसाइट" (Erythrocyte) भनिन्छ, हाम्रो रगतमा सबैभन्दा धेरै पाइने कोषिका हो।
एक स्वस्थ वयस्क व्यक्तिको शरीरमा करिब २० देखि ३० ट्रिलियन (Trillion) रातो रक्तकोषिका हुन्छन्।

यी कोषिकाको मुख्य कामहरू:
✓ फोक्सोबाट अक्सिजन शरीरभरि पुर्‍याउने
✓ शरीरका भागबाट कार्बन डाइअक्साइड फोक्सोसम्म ल्याउने
✓ शरीरलाई ऊर्जा उत्पादन गर्न सहयोग गर्ने
✓ मस्तिष्क, मुटु, मिर्गौला लगायत सबै अंगलाई स्वस्थ राख्ने

रातो रक्तकोषिकाभित्र "हेमोग्लोबिन" (Hemoglobin) नामक प्रोटिन हुन्छ। यही प्रोटिनले अक्सिजन बोकेर शरीरभरि पुर्‍याउने काम गर्छ र रगतलाई रातो रङ दिन्छ।
यदि शरीरमा पर्याप्त मात्रामा स्वस्थ रातो रक्तकोषिका भएनन् भने शरीरले पर्याप्त अक्सिजन प्राप्त गर्न सक्दैन। फलस्वरूप कमजोरी, थकान, चक्कर र अन्य स्वास्थ्य समस्याहरू देखिन सक्छन्।

रातो रक्तकोषिकाको विशेष बनावट
रातो रक्तकोषिका अन्य अधिकांश कोषिकाभन्दा फरक हुन्छन्।
परिपक्व रातो रक्तकोषिकामा केन्द्रक (Nucleus) हुँदैन। यसको आकार बीचमा अलिकति पातलो र किनारामा बाक्लो हुने "बाइकोन्केभ डिस्क" (Biconcave Disc) जस्तो हुन्छ।

यस प्रकारको बनावटले तीन महत्वपूर्ण फाइदा दिन्छ:
✓ अक्सिजन आदानप्रदान गर्न बढी सतह उपलब्ध हुन्छ
✓ साना-साना रक्तनलीहरूबाट सजिलै यात्रा गर्न सक्छ
✓ हेमोग्लोबिनका लागि बढी ठाउँ उपलब्ध हुन्छ
एउटा रातो रक्तकोषिकाको आकार करिब ७–८ माइक्रोमिटर मात्र हुन्छ। त्यसैले यसलाई नाङ्गो आँखाले देख्न सकिँदैन।

रातो रक्तकोषिका कहाँ बन्छन्?
रातो रक्तकोषिका हाम्रो शरीरको हड्डीभित्र रहेको बोन म्यारो (Bone Marrow) मा उत्पादन हुन्छन्।
यस प्रक्रियालाई "एरिथ्रोपोएसिस" (Erythropoiesis) भनिन्छ।
जब शरीरमा अक्सिजनको मात्रा कम हुन्छ, मिर्गौलाले "एरिथ्रोपोइटिन" (EPO) नामक हर्मोन उत्पादन गर्छ। यसले बोन म्यारोलाई थप रातो रक्तकोषिका बनाउन संकेत दिन्छ।
स्वस्थ रातो रक्तकोषिका बनाउन निम्न पोषक तत्त्वहरू आवश्यक हुन्छन्:
• आइरन (फलाम)
• भिटामिन B12
• फोलेट (भिटामिन B9)
• भिटामिन B6
• प्रोटिन
यी पोषक तत्त्वहरूको कमी भएमा रक्तअल्पता (Anemia) हुन सक्छ।
नेपालमा रक्तअल्पता किन ठूलो समस्या हो?
नेपालमा विशेष गरी:
• गर्भवती महिलाहरू
• किशोरीहरू
• बालबालिकाहरू
• वृद्ध व्यक्तिहरू

मा आइरनको कमीका कारण हुने रक्तअल्पता धेरै देखिन्छ।
यदि तपाईंलाई बारम्बार:
✓ थकान लाग्छ
✓ चक्कर आउँछ
✓ अनुहार फिक्का देखिन्छ
✓ सास फुल्छ
✓ मुटु छिटो धड्किन्छ
भने रगत जाँच गराउनु उपयुक्त हुन्छ।
समयमै पत्ता लगाउन सके रक्तअल्पताको उपचार सम्भव हुन्छ।
