Frequently Asked Questions

Most donors feel a small pinch when the needle is inserted; the collection itself is not painful and takes only a few minutes.

Whole blood donors typically wait 8–12 weeks between donations depending on local regulations. Platelets and plasma have different intervals.

Some medications defer donation for a period of time; others are acceptable. Always disclose medicines during screening so the blood center can advise.
