PSA, Free: Total Ratio Reflex$82
Learn MoreNOTE: This test can only be purchased by men with suspect PSA over 4 mg/dL. Free PSA will not be provided for PSA under 4 ng/mL.
PSA circulates through the body in two ways; bound to other proteins or by itself. Unbound PSA is called free PSA. A free-PSA test will measure the percentage of unbound PSA while a PSA test is used to measure the total of free and bound PSA in the blood. The free PSA is a defective variant of normal PSA that can no longer bind to other proteins and so circulates in the blood in the free form. Although the reason why this is the case is poorly understood - patients with prostate cancer may have lower free PSA levels than those with a benign prostate condition.

Immunoglobulin A Test$32
Learn MoreImmunoglobulin A (IgA) is a crucial antibody in the immune system, predominantly found in mucous membranes of the respiratory and gastrointestinal tracts. It helps protect against infections by neutralizing pathogens before they can cause harm. Testing IgA levels can provide insights into immune health, indicating potential issues such as chronic infections, autoimmune diseases, or immunodeficiency disorders. Elevated or decreased IgA levels can signal various health conditions, making this test valuable for diagnosing and managing immune-related issues. For those experiencing frequent infections or gastrointestinal issues, an IgA test can be an essential diagnostic tool.
