Free Prostate Specific Antigen (PSA) Component
About Test
The Free Prostate Specific Antigen (PSA) test is a laboratory test used to measure the level of free PSA in a person's blood. Prostate Specific Antigen (PSA) is a protein produced by the prostate gland, and it is used as a marker for prostate cancer and other conditions that affect the prostate.
The Free PSA test specifically measures the amount of PSA in the blood that is not bound to other proteins. The amount of free PSA in the blood can provide important information about the risk of prostate cancer and the likelihood of having a cancer that needs treatment.
The Free PSA test is usually done along with a Total PSA test, which measures the total amount of PSA in the blood. The results of both tests can be used together to estimate the risk of prostate cancer and determine the need for further evaluation, such as a biopsy.
It's important to note that the Free PSA test is not a definitive diagnostic test for prostate cancer, and a positive result should be confirmed with other tests such as a biopsy. The results of the Free PSA test should be considered along with a person's overall health status, age, family history, and other factors that may affect PSA levels. A healthcare provider should be consulted to interpret the results of the test and determine the best course of action based on the individual's specific needs and circumstances.
