This test is aslo known as PSA Free and Total Test, PSA Free Test,free to total PSA test.
PSA is found in two forms in the blood. One form, complex PSA, attaches itself to proteins in blood cells. The other, called free PSA, circulates freely in the bloodstream. A percent-free PSA test measures the percentage of free PSA. Results in lower percentages are associated with prostate cancer and may help the doctor decide whether a biopsy is needed.
Free PSA is more common in non-cancerous prostate conditions. So, if you have higher levels of free PSA compared to total PSA you are more likely to have a condition known as benign prostatic hyperplasia (BPH), which is not cancer and can be treated with medications and sometimes surgery.
But if your free PSA levels are low compared to total PSA, then there is a greater chance you may have prostate cancer and you will need further testing to work out if you have the disease.
Input your data
The "Free PSA test" is usually recommended if your PSA test results show that your PSA level is elevated for your age. The result from this test can help your doctor determine if your elevated PSA level could be due to prostate cancer or to a non-cancerous enlargement of your prostate (BPH, benign prostatic hyperplasia).
Your doctor may recommend a free to total PSA test if Prostate Specific Antigen (PSA) - Total testing shows that:
- your PSA level was high (>2 ng/mL for men with family history, or >3 ng/mL for men 50 – 70 years of age) on one or more repeated tests
- your PSA level was just above the normal range, you are a younger man and/or you have a family history of prostate cancer.
The results from this test will help guide your doctor on whether you need further testing and if you need to be referred to a urologist.
