- Prostate-Specific Antigen (PSA), Total and Free, Serum - Mayo . . .
The total PSA range of 4 0 to 10 0 ng mL has been described as a diagnostic "gray zone," in which the free PSA:total PSA ratio helps to determine the relative risk of prostate cancer (see table) Therefore, some urologists recommend using the free PSA:total ratio to help select which men should undergo biopsy
- PSA, % Free - Lab Results explained | HealthMatters. io
Low PSA, % Free: The % Free PSA is the ratio of free (unbound) PSA to total PSA A low % Free PSA (especially below 10%) is associated with a higher risk of prostate cancer Levels between 10-25% indicate moderate risk Interpreting the Combination: Normal PSA Total + Low % Free PSA
- Free total PSA ratio is a powerful predictor of future . . .
Objectives: To evaluate the usefulness of measuring the free total prostate-specific antigen (PSA) ratio (%fPSA) in men with initial PSA levels of 4 1 to 10 0 ng mL as a predictor of the future risk of developing prostate cancer
- Free total PSA ratio | Radiology Reference Article . . .
The free total PSA ratio (f t PSA) is the simple mathematical ratio of the free prostate specific antigen (PSA) in blood serum over the total PSA in blood serum 1,2 It is expressed as a dimensionless quantity 4
- Using the Free-to-total Prostate-specific Antigen Ratio to . . .
The free-to-total PSA ratio has been recommended as an effective strategy to improve the specificity of total PSA for “gray zone” values between 2 0 and 10 0 ng ml Our meta-analysis showed that using the investigator-selected free-to-total PSA cut point yielded modest revisions of probability estimates for cancer
- Free PSA and Prostate Cancer: What You Should Know - Healthline
Free PSA is measured as the proportion of free PSA to total PSA According to older research still used as guidance right now, in men with a total PSA between 4ng mL and 10 ng mL:
- Free to Total PSA Testing | PCFA
The report will show your levels of free PSA and total PSA as well as a calculated ratio showing the difference between the two (free PSA total PSA) If you have less free PSA than total PSA in the blood, the free to total ratio will be low and your risk of prostate cancer is higher
- Free PSA: Test, results, and prostate cancer - Medical News Today
Free PSA ranges can vary, but generally, a higher ratio of free PSA to total PSA indicates a lower risk of prostate cancer On the other hand, a low ratio of free PSA to total PSA indicates a
