Prostate-Specific Antigen (PSA) details
Description
Prostate-specific antigen (PSA) is a protein produced by the prostate gland, and this test is used mainly to help screen for and monitor treatment response in prostate cancer. However, PSA isn't specific to cancer — it also commonly rises with benign prostate enlargement (very common with age), prostate inflammation or infection, and even recent ejaculation or vigorous exercise — so an elevated result doesn't automatically mean cancer, and screening decisions (whether and how often to test) are typically individualized based on age, family history, and a discussion of the test's benefits and limitations with a doctor.

Explore available tests to better understand your results and gain deeper insights into your health.
Single marker
Prostate-Specific Antigen (PSA)
$14.99
This test measures total PSA (Prostate-Specific Antigen) in the blood. It is useful for monitoring recurrence and response to treatment in patients with a history of prostate cancer. Elevated levels have been reported in inflammatory conditions of the prostate, benign prostatic hypertrophy, and prostate cancer.
Biomarkers
- Prostate-Specific Antigen (PSA) A protein made by the prostate gland. Used to help screen for and monitor prostate cancer, though it can also rise with benign prostate conditions.
PSA, Total (2.5 ng/mL cutoff)
$10.99
This test measures the level of PSA (Prostate-Specific Antigen) in the blood to help identify conditions like prostate cancer, benign prostatic hypertrophy (enlargement of the prostate), and inflammation of the prostate. Elevated PSA levels can indicate these conditions, making this test a crucial part of prostate health screening.
Biomarkers
- Prostate-Specific Antigen (PSA) A protein made by the prostate gland. Used to help screen for and monitor prostate cancer, though it can also rise with benign prostate conditions.
Panel
Functional Health Panel (Male)
$753.99
This comprehensive panel assesses biomarkers related to hormonal health, thyroid function, metabolism, cardiovascular health, inflammation, nutrient status, and environmental exposures. The results can help provide a broader picture of overall health and support personalized wellness and treatment strategies.
Biomarkers
- Free Testosterone The small portion of your testosterone that's unbound and biologically active, considered a more accurate reflection of usable hormone than total testosterone.

- GGT Gamma-glutamyl transferase, a liver enzyme sensitive to bile duct problems and alcohol use, often used alongside other liver tests.
- Thyroid-Stimulating Hormone (TSH) A pituitary hormone that signals your thyroid to produce hormone. The primary screening test for both underactive and overactive thyroid conditions.
- Prostate-specific antigen (PSA), Free
- SHBG (Sex Hormone-Binding Globulin) A protein that binds and transports testosterone and estrogen in your blood, determining how much hormone is 'free' and active. Important for interpreting sex hormone results.
- Leptin A hormone released by fat cells that helps regulate appetite and energy balance. Levels generally rise with increased body fat.
- T3, Free (fT3) The unbound, biologically active portion of triiodothyronine (T3), the more potent thyroid hormone. Used to evaluate thyroid function.
- Homocysteine An amino acid byproduct of protein metabolism. Elevated levels are linked to increased cardiovascular risk and can reflect low B vitamin (B12, folate, B6) status.
- Apolipoprotein B The main protein found on LDL and other 'bad' cholesterol particles. Considered a strong indicator of cardiovascular risk, since each particle carries one ApoB molecule.
- Rheumatoid factor
- Prostate-specific antigen (PSA), % Free
- Lipase An enzyme that helps digest fat, produced mainly by the pancreas. Elevated levels are a key marker for pancreatitis.
- Lead (Venous) Measures lead levels in your blood, used to assess exposure to this toxic heavy metal.
- LDL Small
- Albumin The main protein made by your liver, which helps balance fluids and carries hormones, vitamins, and medications through your blood. Low levels can point to liver, kidney, or nutrition issues.
- Uric Acid A waste product from the breakdown of purines. Elevated levels are linked to gout and kidney stones, and can also reflect metabolic health.
- Zinc Measures zinc, a trace mineral essential for immune function, wound healing, and taste/smell.
- Total Iron Binding Capacity (TIBC) Total Iron-Binding Capacity — reflects how much transferrin (the iron-carrying protein) is available in your blood, used with iron and ferritin to evaluate iron status.
- Iron % Saturation The percentage of transferrin (your iron-carrying protein) that's currently occupied by iron — a key marker for detecting iron deficiency or overload.
- Large VLDL-P Counts the largest VLDL particles, which carry a high amount of triglycerides and are associated with greater cardiovascular risk.

- Ferritin Reflects your body's stored iron levels. Low levels point to iron deficiency; high levels can indicate iron overload or, since it's also an inflammation marker, other conditions.
- LDL Size Measures the average size of your LDL ('bad' cholesterol) particles; smaller, denser particles are considered more likely to contribute to artery plaque.
