This test is aslo known as percent-free PSA (%fPSA), free/total PSA ratio (f/t PSA).
The ratio of free PSA to total PSA aids your doctor for assessing the prostate cancer risk, where a higher ratio often means lower risk and a lower ratio may indicate higher risk.
Free PSA is a specific part of the prostate-specific antigen PSA that circulates in the blood, not bound to proteins. This analysis provides important information for men being investigated for prostate cancer. PSA is produced by the prostate gland and small amounts occur naturally in the blood. An increased PSA value can indicate prostate cancer, but high values can also occur in other conditions such as prostate enlargement. By analyzing the ratio between free PSA and total PSA, you can get an even better basis for assessing the risk of prostate cancer, with special limit values for different age groups. Symptoms of prostate cancer include changes in urination patterns and blood in the urine, but these symptoms can also have other causes., but these symptoms can also have other causes.

The free to total PSA test is a comparison between the total and free PSA levels in the blood & your doctor may recommend when standard PSA tests show high PSA levels for your age.
Free PSA levels may help identify benign prostatic hyperplasia, as free PSA is more commonly associated with non-cancerous prostate conditions.
It uses a ratio of free PSA to total PSA to predict prostate cancer risk. Your doctor will talk to you about what the test results mean for you & will also discuss if further examinations or tests are recommended.
Your doctor may also order this ration test based on the following systems:
1. Symptoms of stage 1 prostate cancer: The early stages of prostate cancer usually don’t have warning signs.
2. Warning signs of prostate cancer: As prostate cancer progresses, you may develop the following symptoms:
- Peeing changes - This may include urinary incontinence (including urge incontinence), a weak urine flow and pain or burning when you pee (dysuria).
- Pain in your lower back, hips or chest - This may indicate that prostate cancer has spread to other areas of your body.
- Blood in your pee or semen - Prostate cancer can affect areas of your urinary and reproductive systems, which can cause blood in your pee (hematuria) or semen (hematospermia).
- Bone pain - Advanced prostate cancer can spread to your bones and cause pain.
- Unexplained weight loss - Losing weight without trying can be a sign of cancer.
- Erectile dysfunction and painful ejaculation (dysorgasmia or orgasmalgia) - Prostate cancer may affect your ability to get and maintain an erection. It may also cause pain when you ejaculate.
