| Abstract | Background: We observed an increase in the frequency of false-positive (FP) human immunodeficiency virus (HIV) test results that correlated with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) prevalence. We measured FP rates of laboratory-based fourth-generation HIV antigen/antibody test among those with polymerase chain reaction (PCR)-confirmed infection with SARS-CoV-2 compared with FP rate of those who tested SARS-CoV-2 PCR-negative. Methods: All patients PCR tested for SARS-CoV-2 within 2 weeks of an HIV fourth-generation assay were selected. Positive HIV fourth-generation assays were reviewed and divided into groups of FP, true positive (TP), and presumptive negative (PN). Variables included age, race, ethnicity, gender, pregnancy, and Coronavirus Disease 2019 (COVID-19) immunization status. Associations with positive SARS-CoV-2 tests were assessed using linear logistic regression. Multivariate logistic regression was used to assess sets of variables. Results: There were 31 910 medical records that met criteria. The frequency of SARS-CoV-2 positive tests was calculated in groups of HIV TP, FP, and PN. In total, 31 575 patients had PN HIV test result, 248 patients had TP, and 87 patients had FP. Those with HIV FP tests had the highest percentage of COVID-19-positive test results at 19.5%, which was significantly higher than HIV PN (11.3%; P = .016) and HIV TP (7.7%; P = .002). After adjustment for all covariates, only FP HIV was significantly associated with COVID-19 (odds ratio, 4.22; P = .001). Conclusions: This study reveals that patients with positive SARS-CoV-2 PCR tests are significantly more likely to have an FP fourth-generation HIV test than those with negative SARS-CoV-2 PCR tests. |
