Verified facts about blood and donation, the shareable kind, each one checked, none invented. ## The honest answer One donation can be split into red cells, plasma and platelets for up to three patients. Blood has no substitute. India needs tens of millions of units yearly; voluntary donors supply the gap. The full list lives on this page: storage limits (red cells ~35,42 days, platelets ~5 days, plasma a year frozen), the O− emergency rule, the Rh pregnancy story, Assam’s replacement-donor problem, and more. ## If this is your moment Blood cannot wait for curiosity to settle, patients wait in hours, not weeks. If you are healthy and between 18 and 65, register as a donor (two minutes, phone OTP) and let the system call you only when someone near you actually needs your group.
