NOTE: 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.

Ferritin is a protein that stores iron. Red blood cells need iron to form normally and carry oxygen around your body. Low levels of ferritin lead to iron deficiency anemia, which means you have too few red blood cells. High levels of ferritin can damage your joints, heart, liver, and pancreas.

This test measures the amount of dihydrotestosterone (DHT) in the blood.  Low DHT has been associated with low libido and high DHT has been linked to acne, hair loss and benign prostatic inflammation in a minority of men.

A complete blood count CBC with differential test panel measures several components of your blood including:Red blood cells, which carry oxygen, White blood cells, which fight infection, Hemoglobin, the oxygen-carrying protein in red blood cells, Hematocrit, the proportion of red blood cells to the fluid component in your blood (which correlated with blood thickness), and Platelets, which help with blood clotting. This is also called Complete Blood Count (CBC) with Differential and Platelets Blood Test

Renin, also known as angiotensinogenase, is an enzyme that the kidneys produce to regulate aldosterone production. It’s also essential in the renin–angiotensin aldosterone system (RAAS) which maintains your body’s fluid balance and blood pressure. Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. Aldosterone tends to promote sodium and water retention, and lower plasma postasium concentrations.
