目的:评价免疫印迹法检测胰岛自身抗体(GAD-A、ICA、IAA)与酶联免疫法测ICA、GAD-A放射免疫法测IAA结果的一致性。方法:采用免疫印迹法测定81例糖尿病患者胰岛自身抗体,将结果与酶联免疫法测定的GAD-A、ICA,放射免疫法测定IAA结果进行比较。结果:免疫印迹法阳性检出率为:GAD-A 51.8%,ICA 18.5%,IAA 27.1%;酶联免疫法(GAD-A、ICA)、放射免疫法(IAA)阳性检出率:GAD-A 32.1%,ICA 34.5%,IAA 30.8%;上述两组结果进行比较,两组相比ICA和GAD-A有统计学差异(P lt;0.05),IAA无统计学差异。两组结果一致率比较:GAD-A 50.6%,ICA 64.2%,IAA 69.1%。结论:与临床常用酶联免疫法检测GAD-A、ICA,放射免疫法检测IAA比较,免疫印迹法和酶联免疫法在ICA及GAD-A阳性检出率上的差异有显著性,和放射免疫法在IAA阳性检出率上差异无显著性。
