Human immunodeficiency virus (HIV) infection screening and diagnosis are critical to control the HIV epidemic. Testing for anti-HIV antibodies (Ab) and antigens (Ag) in blood samples is the first step to screen people who have been potentially exposed to the virus. This study aimed to evaluate the performance of the MAGLUMI HIV Ab/Ag Combi for detection of HIV antibodies and antigens. We used residual samples to assess the diagnostic specificity and sensitivity of the MAGLUMI HIV Ab/Ag Combi retrospectively. All samples that met the test criteria were tested with the MAGLUMI HIV Ab/Ag Combi according to manufacturer's instruction. Results of the MAGLUMI HIV Ab/Ag Combi were compared with the Architect HIV Ag/Ab Combo test. The specificity of the MAGLUMI HIV Ab/Ag Combi was 99.85% in 5,057 unselected blood donors and 100.00% in 213 hospitalized patient samples, respectively. The sensitivity of the Test in 614 HIV-1 Ab, HIV-1 Ag or HIV-2 Ab positive samples was 100.00%. Seroconversion sensitivity from results of 30 panels was comparable between the MAGLUMI HIV Ab/Ag Combi and the Architect assay. The reactivity of the MAGLUMI HIV Ab/Ag Combi test is comparable to the Architect HIV Ag/Ab Combo assay.
