What is a good free PSA score?
What is a good free PSA score?
Safe. Zero to 2.0 ng/mL. Your chance of prostate cancer is very low. Checking your free PSA level may be unneeded.
What is the normal percentage of free PSA?
Below is a table outlining the likelihood of finding prostate cancer based on the percentage of free PSA in men with a total PSA between 4ng/mL and 10 ng/mL, according to the Journal of American Medical Association ….Free PSA.
| Percentage of free PSA | Probability of prostate cancer |
|---|---|
| 20% –25% | 16% |
| Greater than 25% | 8% |
What are the results of the free PSA test?
The free-PSA test measures the percentage of unbound PSA; the PSA test measures the total of both free and bound PSA. Prostate cancer can raise PSA levels, but so can other conditions. These include an enlarged prostate, prostatitis, and advancing age.
Can a total PSA test help diagnose prostate cancer?
Free and total PSA are not the only biomarkers that can help diagnose prostate cancer. Free and total PSA tests can help diagnose prostate problems, including cancer. However, the results are only meaningful when compared with those of a total PSA test. A doctor may order a free PSA test if total PSA levels are high.
What does it mean if your PSA is 2.0?
The same is applied for PSA 2.0 or 3.0: means you’re a cancer free or have your treatment course succeeded and lowered the PSA percentage. A problem with prostate production of prostate specific antigen can lead to very low PSA level. Diminished free PSA with normal PSA total is not fully understood.
Do you need a biopsy after a free PSA test?
Free PSA vs. biopsy. On average, free PSA testing can reduce the need for 20 percent of unnecessary biopsies. It also can help determine if there’s a greater likelihood you have prostate cancer. If your results suggest that you may have prostate cancer, you’ll still need a biopsy to confirm the prostate cancer diagnosis.

How long does it take for a PSA blood test?
This blood test measures the level of freely circulating prostate-specific antigen (PSA) and provides a calculation of the ratio of “free” PSA to total PSA. Test results may take 1-3 business days. What is the prostate and prostate-specific antigen? The prostate is a small gland of the reproductive system of men.
Which is better a high PSA or low PSA?
Free PSA ratio A high total PSA level and a low free PSA level generally indicate a risk for prostate cancer. Free PSA ranges can vary, but in general, a higher ratio of free PSA to total PSA is healthier.
