Prostate-specific antigen, or PSA, is a protein produced by normal, as well as malignant, cells of the prostate gland. The PSA test measures the level of PSA in the blood. For this test, a blood sample is sent ...
The PLS test showed a near-perfect sensitivity (98.51%) and an intermediate specificity (62.75%). The quantitative model through PLS regression showed a good correlation between PSA values and the spectral features (r = 0.605). This preliminary study suggests that Raman spectroscopy could be ...

Among the 291 men with abnormal value, 40% had values return to the normal range on at least one subsequent occasion.GramlingDepartment of Family MedicineRobertDepartment of Family MedicineJournal of Family PracticeGramling, R. 2003. "Many Abnormal PSA Test Results Normalize over Time." The ...
If your test shows you have a high PSA, that doesn't necessarily mean you have cancer. Your doctor will likely have you take another PSA test to make sure your level is higher than normal. Your doctor can also order other tests to help figure out why your PSA levels are high, such ...
It is estimated that normal values are around 0.7 ng/ml in men under 50 years, 0.9 ng/ml in men between 50 and 60 years of age, 1.2 ng/ml in men from 60 to 70 years, and 1.5 ng/ml in men older than 70. Clearly the natural aging process increases the size of the prostate ...
Phi test: The Prostate Health Index (PHI or Phi) combines three blood tests for prostate-specific antigen (PSA), total PSA, free PSA, and pro-PSA. These are different fractions of PSA antigens found in the blood. Experts believe that these values give a more accurate Phi score and better...
The PSA screening blood test measures the levels of PSA circulating in the blood. Both normal prostate cells and cancer cells make PSA. While prostate cancer cells tend to produce less PSA than normal cells, they allow PSA to more easily pass through the cell wall and eventually wind up in...
Population-based Analysis of Normal Total PSA and Percentage of Free/Total PSA Values: Results From Screening Cohort To examine the distribution of total prostate-specific antigen (tPSA) and percentage of free/total PSA (%f/tPSA) values in patients undergoing prostate can... U Capitanio,P ...
4, DCA was performed to compare the clinical utility of PSA, MRI, 68Ga-PSMA PET/CT and SUVmax-based prediction models in assisting prostate biopsy decisions at PSA values in the gray zone. The 68Ga-PSMA PET/CT and prediction models had comparable and obviously higher net benefits than the...
