Eligibility
Can You Donate Blood After Surgery?
Healing first; the timeline depends on the operation.
Minor procedures
Tooth extractions, minor skin procedures and endoscopies typically defer days to a few weeks — fully healed and off antibiotics is the bar.
Major surgery
Expect 6–12 months, and 12 months if you received a transfusion yourself. Your body needs its full resources for recovery before sharing them.
Come back when cleared
Post-surgical patients often become the most committed donors — they've seen the receiving end. Register now, set yourself 'paused', and flip to available when cleared.
Frequently asked questions
Does anesthesia itself defer?
It's the surgery and recovery that matter; the anesthetic is long gone within days.
Who decides my exact wait?
