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...
就你的情况看：PSA-fre 意见建议：e/PSA-total比率=0.30>0.15.同时直肠指检前列腺的质地不硬。
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
国内推荐f-PSA/t-PSA大于0.16为正常值。 血清t-PSA水平正常值不超过4ng/ml,如果血清t-PSA介于4-10 ng/ml之间的灰区时,血清f-PSA水平与前列腺癌的发生率呈负相关,f-PSA/t-PSA是提高t-PSA水平位于灰区时前列腺癌检出率的有效方法。当f-PSA/t-PSA大于0.16时前列腺穿刺阳性率约为11.6%,但当f-PSA/t-PSA小...
就是游离PSA和总PSA的比，是判断前列腺癌的一项辅助指标。
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...
free psa高于正常值free psa高于正常值 Free PSA,即游离前列腺特异性抗原,高于正常值可能意味着前列腺癌的风险增加。 PSA是前列腺特异抗原的英文简称,TPSA包括游离的前列腺特异抗原,及与蛋白结合的前列腺特异抗原,因此F/TPSA中文释义为游离PSA与总PSA的比值。临床上主要用来鉴别前列腺癌和前列腺增生,F/TPSA偏高说明...
Although total PSA (tPSA) has been reported to correlate with PV, the relationship between free PSA (fPSA) and PV has not been fully explored. Therefore, we compared tPSA and fPSA as a proxy marker to estimate PV in a large cohort. METHODS Of all 1680 men with no induration by ...
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,...
PSA is present both as free and complexed form. Many researchers have shown total PSA increases in all forms of breast disease, whether cancerous or benign lesions. Few scientists ?have demonstrated that the free form of PSA is the predominant form in breast cancer. 1,2 ?Also the ...
