What does TPSA mean by total prostate specific antigen?

Prostate specific antigen, also known as PSA, is a single-chain glycoprotein secreted by the prostate gland and mainly exists in epithelial cells in the prostate tract. If the patient has prostate cancer, it can show a significant increase in serum PSA, that is, serum prostate specific antigen levels. It is suggested that patients must pay attention to it in time. If they go to the hospital for relevant examination and find that the patient has total prostate specific antigen positive or elevated, they must do further relevant examination in time, such as puncture to take a small amount of prostate pathological tissue for pathological examination, so as to make sure whether there is prostate cancer, and then carry out symptomatic treatment according to the doctor's guidance.
