Prostate-Specific Antigen Test - PSA Test
Prostate-Specific Antigen Test
The Prostate-Specific Antigen Test or PSA test is a common screening for prostate cancer. The PSA test measures a protein that is produced by the prostate gland. Elevated PSA levels from a prostate cancer test may indicate a higher likelihood of having prostate cancer. The PSA test is also used to monitor a person's response to cancer treatment.
It is important to note that not all cases of prostate cancer will show elevated levels on a prostate-specific antigen test and there are other conditions that may cause higher PSA levels besides cancer.
The PSA test is often recommended as a yearly screening for men over the age of 50. Those with a family history of prostate cancer may wish to begin screening earlier. The Prostate-Specific Antigen Free: Total Ratio test is also available for customers looking for a more comprehensive screening.
Turnaround for the prostate-specific antigen test is typically 1 business day.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.
Results may be falsely elevated after a transrectal biopsy.
