【摘要】目的:对比酶联免疫吸附法(酶免法)和胶体金法检测丙肝抗体的价值。方法:选择2023年8月—2023年12月919例参与检验的病例,对研究对象进行血液样本采集。对所采集的血样均分别进行酶免法检测和胶体金法检测,以丙肝病毒核酸检测结果为诊断的金标准,比较不同检测方式对丙肝抗体的阳性检出情况,此外比较不同检测方式的检测时间及重复采样情况。结果:金标准证实其中20份为阳性,阳性率为2.18%。酶免法与胶体金法的阳性检出率分别为95.00%与90.00%,对比差异无统计学意义(P0.05)。胶体金法的检测时间为(8.84±1.21)min,明显短于酶免法的(31.15±4.26)min,差异有统计学意义(P0.05);胶体金法重复采样率为0.76%,低于酶免法的2.50%,对比差异有统计学意义(P0.05)。结论:对于丙肝抗体检测,应用酶免法与胶体金法的阳性检出率均较高,但胶体金法的检测速度快,重复采样率低,因此可作为大规模筛查丙肝的首选方法。
