区分HIV-1p24抗原和HIV抗体检测方法的临床应用
[Abstract]:Objective to study the clinical value of combined detection of (HIV)-1p24 antigen and antibody of HIV. Methods the clinical results of combined detection of HIV-1p24 antigens and antibodies from 2012 to 2016 were summarized, and the results were compared with those of four generations of enzyme-linked reagents which could not distinguish between antigen and antibody, and the results were compared with those of four generations of enzyme-linked reagents which could not distinguish between antigen and antibody. CD4 T lymphocytes and HIV ribonucleic acid (RNA) were detected in HIV-1p24 antigen positive samples. Results from 2012 to 2016, a total of 10 476 samples were tested for HIV-1p24 antigen and antibody. Among them, HIV antibody was positive in 777 cases, HIV-1p24 antigen was positive in 36 cases, both antigen and antibody were positive in 8 cases, and HIV-1p24 antigen alone was positive in 28 cases. Conclusion the combined detection of HIV-1p24 antigen and antibody has high sensitivity and specificity, especially it can distinguish the positive antigen from antibody, greatly shorten the window period and improve the detection rate of acute HIV infection.
