What is prostate specific antigen (PSA)?

Prostate specific antigen is a protein produced by the prostate gland and detected through blood work. When measuring PSA levels, doctors assess whether the prostate is healthy or showing signs of enlargement, inflammation, or other changes that require monitoring.

For men considering or undergoing testosterone replacement therapy, PSA testing is a standard baseline measurement. TRT can affect prostate health, so clinics in Florida typically order a PSA blood test before starting treatment and then at regular intervals during therapy to track any changes. This allows providers to spot potential issues early and adjust treatment if needed.

Current screening guidance suggests baseline PSA testing for men beginning TRT, with follow-up tests determined by your provider's clinical judgment and your individual health profile. Results are usually expressed in nanograms per milliliter (ng/mL), though what constitutes "normal" varies by age and individual factors. If you are starting TRT or need to find a provider who can order appropriate PSA monitoring, qualified diagnostic labs in Florida can handle baseline and ongoing testing as part of your treatment protocol.
