Is it allowed to drink coffee before a 84153 Assay of psa total?

It is generally recommended to avoid coffee and other caffeinated beverages before a PSA (prostate-specific antigen) test, as they can potentially affect the results. Drinking coffee may lead to temporary fluctuations in PSA levels, which could result in inaccurate readings. To ensure the most accurate results, it's best to follow your healthcare provider's specific instructions regarding dietary restrictions prior to the test.
