What it is
The free PSA test measures the part of PSA in the blood that is not bound to proteins. It is usually done along with a total PSA; the ratio of free to total PSA can help a doctor decide whether further testing, such as a biopsy, is needed.
What the price covers
The price covers the free PSA test only. The total PSA (84153) and the blood draw are billed separately.
