Every donation earns a certificate and a donor card, here is what they contain, why they matter, and the one thing they are not (proof of blood group for others). ## The honest answer Certificates record your donation date and centre, useful for leave rules at offices, proud proof for you, and a tracking aid for your intervals. Your donor card or app record shows your last donation date; NBTC intervals (men 90 days, women 120) count from it. The certificate is not a medical report, it does not certify your blood group to hospitals. ## 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.
