There's no one PSA level that's considered normal. In general, PSA levels are higher in older people than in younger people, even in those who don't have prostate cancer or other prostate conditions. Most doctors and medical organizations don't use age-specific PSA ranges because there's ...
(1988) “Measurement of gastrointestinal pH profiles in normal ambulant human subjects”, Gut 29: 1035-1041). The bile salt binding performance of test polymers was evaluated at a polymer concentration of 2.5 mg/ml in the manner described in Protocol 1 above, with the exception that the ...
ｆＰＳＡ／ｔＰＳＡ结果呈明显的偏态分布，并存在年龄依赖性。ｔＰＳＡ和ｆＰＳＡ的参考区间上限值（９５％分位点）在３０～４０岁最低，随后升高，呈“Ｕ”型分布；ｆＰＳＡ／ｔＰＳＡ的参考区间下限值（５％分位点）整体呈降低趋势。结论 分位数回归模型对于建立ＰＳＡ等 非正态分布检验指标的参考区间有...

To determine the sensitivity, the prepared immunosensor was used to detect different concentrations of PSA ranges from 2.5 to 11.0 ng/mL. The exponential plot inFigure 11a shows that the analyte of interest has reached a saturation point.Figure 11b is the linear regression plot, with the linear...
They were classified in three different PSA concentration ranges (0, <4 and ≥4 ng/mL). Cells membrane-engineered with 0.25 µg/mL anti-PSA antibody demonstrated a statistically lower response against the upper (≥4 ng/mL) PSA concentration range. In addition, the cell-based biosensor ...
