【摘要】 目的 :探讨前列腺特异性抗原 (PSA)及其相关指标在前列腺病变诊断中的价值。方法 :采用放射免疫分析法 ,对180例前列腺病变患者联合测定PSA、WPSA、F/T比值。结果 :TPSA及F/T比值可有效区分BPH和CAP ,尤其在论断灰区(PSA为 4 0～ 10 0ng/ml)中效果更明显 ,以TPSA >4 0ng/ml及F/T <0 10为界值时 ,CPA筛选敏感度为达 96%。 结论 :PSA各指标的联合检测对诊断CPA更有效 ,尤其在诊断灰区时 ,可明显提高CPA诊断的准确性。更多还原

【Abstract】 Objective:To evaluate PSA and its correlation index as an indicator for the diagnosis of prostatic disease.Methods:PSA、FPSA、F/T ratio in 180 cases of prostatic disease patients were assayed with radioimmunoassay.Results:All the subjects detected by both PSA and F/T rato were significantly different between patients CAP and patients with BPH,especially TPSA within 4 0～10 0ng/ml(the diagnostic gray zone)as F/T<0 10 was taken as the cut-off value,the sensitivity was as high as 96%.Conclusion:The correlation index of PSA is more useful in the diagnosis of CAP,especially when the PSA is within the diagnostic grayzone更多还原
