The conventional PSA check measures the quantity of PSA, each free as well as bound. The majority of researchers believe that men along with prostate cancer have more bound PSA compared to free PSA in contrast to men who don’t have prostate cancer.
Men that have a superior regular PSA level tend to be candidates with this test. Exactly the same preparations employed for the standard PSA check are suggested for that free PSA check. A doctor can offer particular facts about planning for the check.

The simplest way to determine whether a man includes a low totally free PSA level would be to calculate the proportion of totally free PSA. This is achieved through dividing the worth reported free of charge PSA by the worth reported for that standard or even total, that is free in addition bound PSA. If the result obtained is
- more than 23%, the chance of cancer of the prostate is actually marginal
- under 10%, the chance of cancer of the prostate is higher or more most likely
- in between 10% – 23%, the potential risk of cancer of the prostate is not obvious or not nicely outlined
