The prostate specific antigen test can usually be taken for breakfast.
The Prostate Specific Antigen (PSA) test is a clinically important tumor marker for screening for prostate cancer and assists in determining the need for a prostate biopsy; the term specific refers to antigenic proteins that are synthesized and secreted by the glandular epithelial cells of the prostate gland. The test is not usually affected by eating, so you can usually eat breakfast before the test.
However, when performing the PSA test, it is important to be aware that it is best not to have had sexual intercourse in the last 3 days of the test, as sexual intercourse may result in a mild elevation of the test result and lead to clinical misinterpretation.
Since the patient may need to check other items, it is recommended to consult with the examination hospital for specific examination-related matters to avoid affecting the examination results.
