We compared the values obtained by double-antibody radioimmunoassay (RIA) and immunoenzyme assay (IEA) for measuring the prostatic acid phosphatase (PAP) in human serum. Mean PAP value of IEA in normal persons was 0.582 +/- 0.228 ng/ml (M+2SD, 1.038 ng/ml). Correction of two methods in benign prostatic hypertrophy (BPH) and prostate cancer patients was excellent [r = 0.9504, Y (IEA) = -0.4378 + 0.6529X (RIA)]. False positive cases were two by IEA and one by RIA in BPH patients.
我们比较了采用双抗体放射免疫测定法（RIA）和免疫酶测定法（IEA）测定人血清中前列腺酸性磷酸酶（PAP）所获得的值。正常人IEA法测定的PAP均值为0.582±0.228 ng/ml（M + 2SD，1.038 ng/ml）。在良性前列腺增生（BPH）和前列腺癌患者中，两种方法的校正效果良好[r = 0.9504，Y（IEA）= -0.4378 + 0.6529X（RIA）]。BPH患者中，IEA法有2例假阳性病例，RIA法有1例假阳性病例。
