What is a free PSA test and what is it?

The free prostate antigen test, known as the free PSA test, is used to help detect prostate cancer signs. The test measures the level of the prostate, which is not affected by the prostate in the blood, which can help doctors diagnose problems such as prostate inflammation or cancer.
Free PSA tests are often used in conjunction with other PSA tests to confirm diagnosis or test results. Free PSA tests can be used instead of biopsies if the doctor suspects prostate cancer, but a biopsy may be necessary.

In this article, we study when a free PSA test is used, how it differs from the overall PSA test, and what results mean. What is the difference between PSA and PSA free?
Free PSA test
Doctors can use the prostate specific antigen test to detect signs of prostate cancer.
Prostate Specific Antigen (PSA) is a protein made mainly in the prostate. PSA is released slightly into the blood stream during each ejaculation, and PSA in ejaculation facilitates semen to transfer sperm to the fallopian tubes during pregnancy.

PSA can be two basic conditions. It can be binding to another protein or float freely.

Total PSA and free PSA tests measure PSA levels in the blood. The results help doctors diagnose problems such as prostate cancer and prostate inflammation.

The tests are a bit different. The overall PSA test measures all PSAs, including attached antigens and those that float freely.

A free PSA test measures only the amount of PSA that floats freely in the bloodstream, without being associated with a different protein.

Both tests are used to diagnose prostate problems. A person may be more likely to develop prostate cancer when they have higher levels of total PSA and lower PSA free levels.

In some cases, normal test results do not rule out prostate cancer. Even when PSA levels are too low to indicate a problem, a person may develop prostate cancer. People can also have high levels of PSA without cancer.

Because of this, PSA tests are often only part of the complete diagnosis. If the results are not quite clear, many doctors still recommend biopsies or additional tests to help diagnose.

Does the person need both tests?
The overall PSA test and the free PSA test are often arranged together. This is because the free PSA test measures the amount of PSA being released, and this result is best understood when compared to the total amount of PSA in the bloodstream. Seven reasons for high PSA are not cancer

When total PSA levels are higher than the appropriate range, a person may be at risk of developing prostate cancer.
Doctors explain the results according to several factors, including:

Total PSA

The overall PSA ranges may vary slightly. According to the review of studies, the natural ranges of total PSA in nanograms per milliliter (ng / ml) are:

49 years or less: 0.0-2.5 ng / mL
From 50 to 59 years: 0.0-3.5 ng / mL
From 60 to 69 years: 0.0-4.5 ng / mL
70 years or older: 0.0-6.5 ng / mL
When total PSA levels are higher than the appropriate range, the person has an increased risk of prostate cancer. It does not show conclusively that a person has cancer. After that, doctors will compare the results of this test with the results of a free PSA test.
