Can You Donate Blood If You Have an STD?
Blood donation eligibility around STDs depends on which specific infection, and whether it's active, treated, or in your history — there isn't one blanket rule that covers every situation.
What generally disqualifies a donation
A currently active bacterial STD (like chlamydia, gonorrhea, or syphilis) typically requires waiting until treatment is completed before donating. HIV-positive status is a permanent disqualification for blood donation in the US, regardless of treatment status or viral load. Hepatitis B or C, active or with certain history, generally disqualifies donation as well, with specifics depending on the exact situation.
What changed in 2023
The FDA finalized a significant policy change in May 2023, moving away from blanket time-based deferrals that had specifically targeted men who have sex with men and women who have sex with those men. Blood centers now use the same individual, behavior-based risk questions for every donor regardless of gender or sexual orientation — asking about new or multiple sexual partners and specific higher-risk activities in the past three months, rather than categorically deferring based on sexual orientation. Most blood centers implemented this by the end of 2023.
The honest bottom line
If you're unsure whether a past or current STD affects your eligibility, the blood donation center's own screening questionnaire (completed before every donation) is the authoritative source — eligibility criteria are specific and do change, so it's worth checking directly with the organization you're donating through rather than relying on older general assumptions.
