The free PSA percent (%) test is performed to detect the presence of prostate cancer in individuals. It measures the levels of free and total PSA (prostate specific antigen) and their ratio.
PSA or the prostate specific antigen is an enzyme that is mainly produced by the prostate gland, which is a part of the male urinary and reproductive systems. PSA is mainly found in the semen, which is also produced by the prostate, though trace amounts of the enzyme can also be found in the blood. PSA binds itself to the protein present in semen and breaks them down. Based on whether it is bound to any proteins, PSA is categorised into two types – free PSA and bound PSA. The free PSA percent (serum) test measures the levels of free PSA and total PSA in the blood, which are used to calculate the ratio of free to total PSA. The results of the free and total PSA test, along with their ratio, can help doctors analyse one’s risk of developing prostate cancer. Based on the results, a doctor may prescribe further tests as well for a more detailed diagnosis.....Read More

The free PSA percent (%) test is performed to detect the presence of prostate cancer in individuals.
The free PSA percent test can be prescribed to screen for prostate cancer or other conditions, like an inflamed or enlarged prostate, by measuring the levels of free and total PSA. The test may also be prescribed to check how effective a treatment plan is or to screen for the recurrence of cancer. Some of the symptoms that indicate a condition of the prostate include:
If a person is displaying these symptoms, a ratio of free to total PSA can help doctors detect prostate conditions without having to resort to a biopsy, which may still be required in case the results show elevated PSA levels and a low free to total PSA ratio. There are also several risk factors that increase the chance of developing prostate cancer. These include:
The free prostate specific antigen percent test can be booked online at Max Lab. The report for the same will be generated within 24 hours of sample collection. As there are several factors like age, UTIs, surgery, prostatic injuries, etc. that can affect the PSA levels, it is always best to consult a doctor who will be able to properly analyse the results and suggest any further testing, if required.
