ACID PHOSPHATASE

You should get an acid phosphatase test if your doctor suspects advanced prostate cancer, especially with bone pain, or needs additional information alongside PSA testing. It may also be advised for unexplained bone disease, suspected Gaucher disease, and monitoring prostate cancer treatment. It is also used in forensic investigations of sexual assault.

Fasting is usually not required for an acid phosphatase test, though some labs may advise it. Avoid prostate examination, prostate massage, catheterization, cystoscopy, or biopsy for at least 48 hours beforehand, as these can raise levels. Also avoid ejaculation and cycling for 48 hours. Inform your doctor about any hormonal medicines you take.

Fasting is usually not required for an acid phosphatase test. You can eat and drink normally, though some labs may recommend fasting, so follow their instructions. More importantly, avoid prostate examination, procedures, ejaculation, and cycling for 48 hours beforehand, as these can falsely raise results.
