Can I donate blood?

The basic rules in India, set by the National Blood Transfusion Council and the Drugs & Cosmetics Act. The final word is always the medical check at the blood centre, these are the gates before it.

The basics (most people pass)

  • Age between 18 and 65.
  • Weight 50 kg or more.
  • Haemoglobin 12.5 g/dL or more (tested free at the centre).
  • Normal temperature and pulse; blood pressure roughly 100–140 over 60–90.
  • Generally healthy, no fever, cold or infection today.

How often?

Men: every 3 months (90 days). Women: every 4 months (120 days). Our platform hides you from matching automatically until your interval clears, you'll never be asked too early.

Common deferrals (temporary, come back later)

  • Fever or infection, wait until fully recovered (usually 2 weeks).
  • New tattoo or piercing, 6 months.
  • Recent surgery, pregnancy or breastfeeding, as advised by the centre (childbirth: typically 1 year after delivery, once lactation has stopped).
  • Malaria, 3 months after treatment in endemic areas (check with the centre).
  • Recent vaccination, varies; most are fine after 24–48 hours, some need 2–4 weeks.
  • Antibiotics, usually 5–14 days after the course ends.
  • Alcohol in the last 24 hours.

Can I donate if…

The quick answers. When the answer is “ask the centre”, that is the honest answer — the doctor at the blood centre decides on the day.

…I'm 17, or over 65? 18–65 is the standard window in India. First-time donors above 65 are usually not accepted; regular donors may continue with the centre's approval.

…I weigh less than 50 kg? Not yet — 50 kg is the floor for a safe standard donation (350–450 ml by weight).

…I got a tattoo or piercing? After 6 months, once healed. See deferrals.

…I'm on medication? Often yes — controlled thyroid, BP and similar conditions are commonly fine. Bring your prescription list; the centre doctor decides.

…I have diabetes? Well-controlled diabetes without complications is usually acceptable. The centre makes the call.

…I'm pregnant or breastfeeding? Not while pregnant or breastfeeding. Typically 1 year after delivery, once lactation has stopped.

…I had dengue, malaria or fever recently? Fever: ~2 weeks after full recovery. Malaria: 3 months after treatment in endemic areas. Dengue: once fully recovered and cleared by your doctor — tell the centre.

…I smoke or drink? Smoking doesn't disqualify. No alcohol in the 24 hours before donating.

…I'm vegetarian? Yes — iron and protein from lentils, spinach, jaggery, dates with vitamin C keep haemoglobin donation-ready.

…I've had surgery? Wait until fully recovered and cleared, usually a few months depending on the surgery — ask the centre.

Rare blood groups matter most. O− can help every patient but only 1 in ~20 Indians has it. Negative groups (O−, B−, A−, AB−) are chronically short in Assam's banks. If you're negative, the network needs you specifically.

Eligibility questions

I donated 2 months ago, can I donate again for a friend?

No, the safe minimum is 3 months for men, 4 for women. But you can register and be matched after your interval clears, or bring another donor.

I take regular medication, can I donate?

Often yes (e.g. thyroid or BP medication when controlled), but the doctor at the blood centre decides. Bring your prescription list.

Can I donate if I have diabetes?

Well-controlled diabetes without complications is usually acceptable. The centre doctor makes the call.

Does donating blood hurt or make me weak?

The needle pinch lasts a second; 350–450 ml is drawn (by weight) and replaced by your body within days. Eat and drink normally before and after.

How long does a donation take?

About 10 minutes on the couch, 30–45 minutes at the centre including check-up, snack and rest.

I'm under 50 kg but healthy — why not?

The volume drawn is calibrated to body weight; below 50 kg the safe draw becomes too small to process. The floor protects you.

Can I donate if I had dengue last month?

Only after full recovery and your doctor's clearance — tell the centre about it. Post-viral deferrals are decided case by case.

I'm 66 and donated for years — can I continue?

Regular donors above 65 are assessed individually by the centre. Register anyway; the interval rules keep you safe either way.
