Can I donate blood?
Sixty seconds, a dozen questions, an honest answer: ready now, wait until a date, or ask a doctor. Your answers stay on your phone, nothing is sent anywhere.
The basics
Right now / recently
Health background
What the checker checks, and what it cannot
The four gates above are the national NBTC basics: age 18,65, weight 50 kg or more, the donation gap (3 months for men, 4 for women), and no recent fever or infection. They are the same questions the camp doctor asks.
What it cannot check: everything a doctor must see, your haemoglobin on the day, your veins, your medicines, your past illnesses. Answer the deeper questions with the guides below, then let the centre's screening make the final call. Nothing here is stored or sent anywhere.
Common "no" answers, and what to do
Under 50 kg? Eat well and train for it, the underweight donor guide. Recent fever or antibiotics? Wait 14 days after full recovery, the rules on fever and colds. Diabetes or BP on tablets? Usually fine, details here. Tattoo in the last 6 months? Wait it out, tattoo rules.
Every deeper rule lives in the full eligibility page and the FAQ.
