Method:This paper established the indirect enzyme linked immunosorbent assay(ELISA)technigue to detect ACA in the sera of 32 patients with RSA,and ANA,anti ss DNA,anti ds DNA,RF,as well as anti Sm were measured simultaneously.

• 方法：应用间接酶联免疫吸附试验（ELISA）法检测32例RSA患者血清中的ACA，同时也测定了抗核抗体（ANA）、抗单链DNA（抗s－DNA）、抗双链DNA（抗ds－DNA）、RF、抗平滑肌抗体（抗Sm抗体）。
