像你说的这种情况,这个是前列腺癌的特异性抗体,升高还是需要结合病人前列腺超生
回答:病情分析: 你好,PSA的正常值小于4ug/ml.前列腺肥大与前列腺炎这两种良性疾病,会造成PSA升高,浓度通常在4至10ug/ml之间.如果PSA浓度大于10ug/ml,发生前列腺癌的机会就增加,要进一步做直肠超声波检查支持诊断. 指导意见: 一般血清中f-PSA/t-PSA大于或等于0.15可能为前列腺肥大,小于0.15前列腺癌可...
Reports on how the ratio of free to total (percent free) prostate specific antigen (PSA) can be used to monitor prostate cancer in men taking finasteride. Finasteride's ability to lower free and ...
你好,患者化验的PSA结果异常,正常值小于4,建议先行直肠指诊,再行前列腺超声及前列腺核磁检查,肠道...
总前列腺特异抗原(total PSA)是指在血液中测量到的所有前列腺特异抗原的总和。游离前列腺特异抗原(free PSA)是指未与其他蛋白质结合的前列腺特异抗原分子。 如果总PSA正常但游离PSA升高,可能是以下几种情况: 1.早期前列腺癌:前列腺癌通常会导致游离PSA的升高,而总PSA可能仍在正常范围内。 2.直肠指检或前列腺按摩...
▲4Kscore Test. The 4Kscore test takes into account four different prostate-specific biomarkers, namely, total PSA, free PSA, intact PSA, and human kallikrein 2, as well as the patient’s age, prior biopsy history, ...
To ascertain when the serum determination of the free prostate-specific antigen (PSA)/total PSA (fPSA/tPSA) ratio is clinically useful, and whether the identification of PSA or prostate-specific membrane antigen (PSM) mRNA in circulating cells has diagnostic advantages over the determination of ...
游离PSA比值(Free PSA Ratio)是一种用于判断前列腺癌风险的指标。它是通过测量血液中的游离前列腺特异性抗原(Free PSA)和总前列腺特异性抗原(Total PSA)的比值来计算得出的。 前列腺特异性抗原(Prostate-Specific Antigen,简称PSA)是一种由前列腺细胞分泌的蛋白质,其主要功能是液化精液,帮助精子在射精时更好地游动...
We examined intermethod differences in total PSA (tPSA) and free PSA (fPSA) measurements. We tested 157 samples with tPSA concentrations of 2 to 10 ng/mL (2-10 mug/L) using 6 PSA/fPSA method pairs and 1 tPSA method: ADVIA Centaur (complexed and total; Siemens Diagnostics, Tarrytown,...
Unlabelled:The normal distribution of values was determined and the age-related reference ranges were established for free PSA, total PSA and free PSA/total PSA ratios. Methods:A total of 414 healthy males (14 to 84 years old) were randomly chosen from the Chinese residing in the central area...
