Why donate blood
Small effort. Huge impact.
India needs millions of units of blood every year, and much of it depends on voluntary donors. Here is why giving blood is good for others — and for you.
Free health check
Every donation includes a mini check-up — haemoglobin, blood pressure, pulse — and screening of the blood.
Your body replenishes
Plasma is replaced within a day or two and red cells within weeks. Healthy adults can donate whole blood every 3 months.
Takes under an hour
The actual donation takes about 10 minutes. Registration, check-up and refreshments make it under an hour.
Emergencies can’t wait
Accidents, surgeries, childbirth, thalassemia and cancer care all depend on blood being available on time.
Feel genuinely good
Few things match knowing that a stranger is alive because you showed up. Be that reason.
