Anti-human immunodeficiency virus type 1 immunoglobulin G in urine was detected by an immunoassay with reverse transcriptase as the antigen and beta-D-galactosidase as the label; this immunoassay was 30-fold more sensitive than the previous immunoassay with peroxidase as the label. The sensitivity and specificity were both 100%. The lowest signal for asymptomatic carriers was 20-fold higher than the highest signal for seronegative subjects.
以逆转录酶为抗原、β-D-半乳糖苷酶为标记,通过免疫测定法检测尿液中的抗1型人类免疫缺陷病毒免疫球蛋白G;该免疫测定法的灵敏度比之前以过氧化物酶为标记的免疫测定法高30倍。灵敏度和特异性均为100%。无症状携带者的最低信号比血清阴性受试者的最高信号高20倍。
