Do Plasma Centers Drug Test?
Evidence-based answer reviewed against SAMHSA cutoffs and FDA assay documentation · Updated September 2026
Quick answer: Plasma centers screen donations for infectious markers — not donor lifestyle; methadone/buprenorphine maintenance donors donate routinely with disclosure.
What they actually screen
Plasma centers test YOUR PLASMA for communicable markers (HIV/HBV/HCV) — not your lifestyle. Pre-donation 'drug screening' myths persist; the protein/band/vein checks dominate eligibility.
Edge cases
Methadone/buprenorphine maintenance donors donate routinely (disclose medications honestly — anticoagulant interactions matter medically). Some centers refuse visibly-impaired donations case-by-case.
