广东省临床检验中心组织广州市九间三级甲等医院的免疫检验专家，抽样调查了九个有生产批文的试剂厂家出品的乙肝检测ＥＬＩＳＡ试剂。结果显示：不同厂家试剂的灵敏度相差１－５个稀释度，精密性为１．２８～６６．３％；九厂家试剂的平均特异性为８９．４～１００％、敏感性为７５～９４％、符合率为８６．５～９５．９％；五种品名试剂的平均特异性ＨＢｓＡｇ９８．８％、抗－ＨＢｓ９７．０％、ＨＢｅＡｇ９９．１％、抗－ＨＢｅ９６．２％、抗－ＨＢｃ８６．５％、平均敏感性ＨＢｓＡｇ８５．５％、抗－ＨＢｓ７８．６％、ＨＢｅＡｇ９０％、抗－ＨＢｅ７０．２％、抗－ＨＢｃ９３．１％，平均符合率ＨＢｓＡｇ９０％、抗－ＨＢｓ８９．９％、ＨＢｅＡｇ９５．１％、抗－ＨＢｅ８６．１％、抗ＨＢｃ９０．６％。
Guangdong Provincial Clinical Laboratory Center organized nine immunization test experts in three Grade A hospitals in Guangzhou to sample and survey nine hepatitis B detection ELISA reagents produced by nine reagent manufacturers with production approval. The results showed that the sensitivities of reagents from different manufacturers differed by 1-5 dilutions and the precision was 1.28-66.3%. The average specificity of the reagents of nine factories was 89.4-100% and the sensitivity was 75-94% , The coincidence rate was 86.5 ~ 95.9%. The average specific HBsAg98.8%, anti-HBs97.0%, HBeAg99.1%, anti-HBe96.2%, anti-HBc86.5 %, The average sensitivity of HBsAg85.5%, anti-HBs78.6%, HBeAg90%, anti-HBe70.2%, anti-HBc93.1%, the average coincidence rate of HBsAg90%, anti-HBs89.9%, HBeAg95.1 %, Anti-HBe86.1%, anti-HBc 90.6%.
