Abstract Background A more time saving, convenient, reproducible, and scalable method is needed to assess total HIV-1 DNA levels. Methods Frozen whole blood and peripheral blood mononuclear cell (PBMC) samples both 200 μl at the same point were used to detect total HIV-1 DNA. Automatic extraction of total HIV-1 DNA was used to ensure the consistency of sample extraction efficiency. The detection reagent was HIV-1 DNA quantitative detection kit and real-time quantitative PCR was utilized. Results Of the 44 included patients, 42 were male and 2 were female, with a median age of 33 years. Thirty-three cases were collected after receiving antiviral treatment, with a median duration of treatment of 3 months, and the other 11 cases were collected before antiviral treatment. The median viral load was 1.83 log10 copies/mL, the median CD4 and CD8 count were 94 and 680 cells/μL, and the median CD4/CD8 ratio was 0.18. The results of the two samples were 3.02 ± 0.39 log10 copies/106 PBMCs in PBMC samples and 3.05 ± 0.40 log10 copies/106 PBMCs in whole blood samples. The detection results of the two methods were highly correlated and consistent by using paired t test (P = 0.370), pearson correlation (r = 0.887, P < 0.0001) and intra-group correlation coefficient (ICC = 0.887, P < 0.0001) and bland-altman [4.55% points were outside the 95% limits of agreement (− 0.340 ~ 0.390)]. Conclusions The results of the whole blood sample test for total HIV-1 DNA are consistent with those of PBMC samples. In a clinical setting it is recommended to use whole blood samples directly for the evaluation of the HIV reservoir.
