Since serological donor-screening tests for HIV were introduced in 1985, the safety of donated blood components has improved dramatically. However, these tests do not completely prevent the risk of transfusion-associated HIV infection related to the use of blood donated during the pre-seroconversion window period. Testing based on nucleic acid amplification is being implemented to screen for HIV-infected blood donated during this period, which has reduced the probability of transmitting HIV through transfusion by shortening the window period. This article describes a case of acute HIV-1 infection, detected using a nucleic acid amplification test (NAT) in a repeat blood donor who donated during the pre-seroconversion window period and whose antigen and anti-HIV antibody expression was observed after molecular marker detection. In addition, the possible route of infection is discussed based on the patient’s history, and finally, the need for NAT technology for blood donor screening is emphasized.
