Blood donation eligibility in Assam, the complete checklist

Full eligibility rules for donating blood in Assam, including intervals, deferrals and what disqualifies you.

Cold, fever, infection, when sickness delays your donation

Fever needs about 2 weeks after recovery. Antibiotics, 5–14 days after the course. Why sick-day blood is never accepted, and when to come back.

Deferred from donating? Here's what it means

Most deferrals are temporary. What to do after common deferrals and when you can return.

Diabetes, blood pressure and medication, can you still donate?

Well-controlled diabetes, blood pressure and thyroid conditions are commonly acceptable for blood donation. What the centre checks, and why declaring everything matters.

Donating blood after a tattoo or piercing

Got a tattoo or piercing? The standard wait is 6 months, once fully healed. Why the rule exists, what counts as healed, and how to donate freely after.

Donating blood after surgery or dental work

Healing comes first. Major surgery commonly means months before donating; dental work ranges from same-day cleaning to days after an extraction.

Donating blood after vaccination

Most routine vaccines, including COVID-19 shots, need only 24–48 hours before you can donate. Which vaccines need longer, and why honesty at the checklist matters.

How often can you donate blood?

Men every 3 months, women every 4, why the interval exists and how we enforce it for you.

Travel and blood donation, why 'where have you been?' matters

Recent travel can affect donation because of infections carried without symptoms, malaria above all. What the questionnaire asks, and how Assam fits in.

Under 50 kg, why the scale says wait

The 50 kg minimum isn't bureaucracy, the donation volume is calibrated to body weight, and below 50 kg the safe draw is too small to process.

Who can donate blood in India, the basic rules

Age, weight, haemoglobin and health requirements per national standards, in plain language.
