- Prostate-Specific Antigen (PSA), Total and Free, Serum - Mayo . . .
When total prostate-specific antigen (PSA) concentration is below 2 0 ng mL, the probability of prostate cancer in asymptomatic men is low, further testing and free PSA may provide little additional information
- What is the difference between PSA and free PSA?
I tend to order a free-PSA test when a total PSA yields borderline results and when the PSA seems to be rising quickly, even if the actual number is relatively low So, while the free-PSA test isn't essential, the results may sway your decision on whether to have a biopsy when combined with other tests
- PSA, % Free - Lab Results explained | HealthMatters. io
A lower % free PSA suggests a higher likelihood of prostate cancer, whereas a higher % free PSA is more indicative of benign conditions like BPH The correlation among these markers lies in their combined use to enhance diagnostic accuracy Total PSA gives an overall measure, while free PSA and % free PSA help refine the interpretation:

- Systematic Differences Between Total and Free Prostate . . .
The free total (f t) PSA ratio has been described to improve specificity of tPSA, in the PSA range of 4–10 µg L (“grey zone”) without affecting its sensitivity [7, 8] Moreover, (f t) PSA ratio calculation improves differentiation of benign prostatic disease (BPH) from prostate cancer, reducing the number of unnecessary biopsies [9, 10]
