What constitutes permanent rejection status for a blood donor?

Permanent rejection status for a blood donor is primarily based on the risk of transmitting infectious diseases through blood donations. In this case, a confirmed positive test for HBsAg (Hepatitis B surface antigen) indicates that the individual was infected with the Hepatitis B virus. This finding suggests that the individual is potentially infectious and poses a risk to recipients of the blood.

Once a donor has a confirmed positive test for HBsAg, they are often permanently deferred from donating blood, as the presence of HBsAg indicates that the virus is still active in the body, or there is a strong risk that it could be. This measure is a critical part of blood safety protocols, as it helps prevent the transmission of Hepatitis B, a serious and potentially fatal liver infection.

In contrast, a tattoo done 5 months previously, close contact with a hepatitis patient, or receiving 2 units of blood transfused 4 months ago would not typically result in permanent rejection. These situations are generally subject to time-limited eligibility criteria and do not represent an ongoing risk of infectious disease transmission in the same absolute manner as a confirmed positive HBsAg test. Consequently, donors with these histories may be eligible to donate once the deferral period has passed, as they
