Lab Test Information

What Test Am I Buying?

-Cortisol, Serum

Why Do I Need These?

Measures the amount of cortisol present in the blood. Released by the adrenal glands, cortisol levels increase in the body when a perceived threat occurs, triggering the "fight or flight" stress response along with adrenaline.

Prolonged periods of cortisol in the blood can result in a lowered immune system response, growth processes, and even your digestive system.

Please be aware that drugs containing estrogen, androgens, synthetic glucocorticoids (Prednisone), and pregnancy can affect levels.

Is Fasting Required?

Fasting is not required prior to taking this test. An ideal time to take this test is in the morning, as cortisol levels will be at their highest.

When Will My Results Be Ready?

Results are typically ready in 7-10 business days or less.
