However, the diagnostic window prior to antibody development limits the utility of conventional serological assays. Conventional laboratorybased nucleic acid testing (LABT) is often hindered by operational complexity and long turnaround times. Point-of-care nucleic acid testing (POCT) provides a rapid alternative.  \nMethods: This multicenter cross-sectional study enrolled 1,829 adults from 13 cities in Jiangsu Province and Kunming, Yunnan Province, who had reactive screening results but negative or indeterminate Western blot outcomes. The diagnostic accuracy, quantitative correlation, and agreement of the POCT (Xpert® HIV-1 Viral Load point-of-care test) were compared with LABT using the Roche COBASTaqMan v2 .0 or Abbott RealTime HIV-1 assays, with follow-upseroconversion serving as the reference standard. Turnaround time from initial screening to NAT result reporting was compared using Kaplan–Meier analysis. Laboratory staff perceptions of POCT usability were evaluated via questionnaire. Results: Using follow-up seroconversion as a reference, POCT demonstrated a sensitivity of 98. 87% and specificity of 100.00%, with almost perfect agreement with LABT (99.76%, Cohen’s κ = 0.994) . Quantitative viral load results exhibited strong correlation between POCT and LABT (r = 0. 89), with 94.64% of paired measurements falling within the limits of agreement.
