患者信息 男,33岁 病情描述 Free-PSA/PSA低 患者咨询 我的Free-PSA/PSA指标低了一点点,有问题吗?正常值是0.25-0.099,这个指标低了0.03。 不会影响,这个指标低是正常的。平时注意饮食规律,少吃辛辣刺激、油腻寒凉生冷的食物,服药忌食萝卜绿豆,戒烟戒酒按时吃饭,定时作息,适度运动,保持心情愉悦。 他平时在健身,...
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...

Results PSA,PSAD of PCa were significantly higher than that of BPH (PSA:46.3±33.8μg/Lvs7.04±6.91 μg/L,P=0.000021;PSAD:1.43±1.21μg.L-1.ml-1vs0.14±0.15ng.ml-1.ml-1,P=0.000055).There's no difference of F/TPSA ratio between BPH and PCa cases (0.22±0.18vs 0.18±0.11,P=...
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 ...

We studied whether adding percent free PSA to total PSA improves prediction of clinically significant prostate cancer and fatal prostate cancer.#A total of 6,727 men within the intervention arm of PLCO (Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial) had baseline percent free PSA. ...
PSA是前列腺特异性抗原(Prostate-Specific Antigen)的缩写。它是一种由前列腺细胞产生的蛋白质,通常通过血液检测来检测前列腺癌的存在。FPSA则是“自由前列腺特异性抗原比值”(Free Prostate-Specific Antigen Ratio)的缩写,是一种PSA的变体,通常用于评估前列腺癌的危险性。PSA和FPSA在哪些方面应用?PSA...
free psa,即游离前列腺特异性抗原,是 PSA 的一种形式,与总 PSA(t-PSA)相对。free psa 主要存在于血浆中,而 t-PSA 既存在于血浆中,也存在于前列腺组织中。研究表明,free psa 与前列腺癌的关联性更强,因此,检测 free psa 水平对前列腺癌的筛查和诊断具有重要意义。 当free psa 高于正常值时,可能的原因有以...
