The normal value for prostate PSA is 0-4ng/mL, but this value may vary due to different testing methods.
PSA refers to prostate-specific antigen, which is a protein. If high levels of PSA can be detected, this may indicate the presence of prostate cancer. If the PSA value is higher than 10 ng/mL, the risk of prostate cancer is significantly higher and the patient will need to undergo a further puncture biopsy to confirm the diagnosis.
If the PSA value is between 4 and 10 ng/mL, it needs to be combined with other data, such as the ratio of free PSA to total PSA, and if the ratio is low, the possibility of prostate cancer needs to be considered. However, many other conditions, such as an enlarged or inflamed prostate, can also increase PSA levels.
If an elevated PSA value occurs, it is recommended to visit a urologist for a definitive diagnosis and prompt treatment.
