摘要 目的探讨血清前列腺特异性抗原(PSA)和血清游离前列腺特异性抗原在前列腺疾病中的诊断价值。方法应用化学发光免疫测定法(CLIA)对前列癌患者(Pca)36例、前列腺增生患者(BPH)81例以及52名无前列腺疾病的正常男性血清的TPSA和FPSA比值进行了检测和分析。结果单独以血清TPSA大于4.0ng/mL作为诊断前列腺的标准,其灵敏度和特异性分别为81.4%、76.7%,若以血清TPSA大于4.0ng/mL为阈值,同时结合FPSA/TPSA并以15%为阈值,诊断前列腺的灵敏度为95.6%,特异性为92.1%。结论联合TPSA、FPSA/TPSA的检测,对前列腺癌诊断的准确率可以大大提高。
