Adrenal Insufficiency and Addison Disease

Are you or someone you know suffering from adrenal insufficiency?

Our adrenal insufficiency testing can give you an accurate reading of the health of your adrenal glands, with results sent confidentially online in 1 to 2 days. 

Adrenal insufficiency is an autoimmune disease that causes the adrenal glands to stop producing enough cortisol. It can be caused by genetic mutations, autoimmune diseases, and infections. The most common symptoms of Addison's Disease are fatigue, muscle weakness, weight loss, and low blood pressure. If left untreated, it can lead to shock and death. We offer lab tests for Addison's Disease and Adrenal Insufficiency, so you can quickly understand your health!

The Aldosterone/Plasma Renin Activity (PRA) Ratio test is a diagnostic test that measures the ratio between aldosterone and plasma renin activity in the blood. This test is used to assess the renin-angiotensin-aldosterone system (RAAS), which plays a crucial role in regulating blood pressure, fluid balance, and electrolyte levels in the body.

Also Known As: CRP Test, Inflammation Test

The C-Reactive Protein (CRP) test measures the levels of C-reactive protein, a substance produced by the liver in response to inflammation in the body. It is a non-specific marker of inflammation and is used to evaluate the presence and intensity of inflammation. The CRP test helps healthcare providers assess the severity of an inflammatory condition and monitor response to treatment.

Also Known As: Cortisol Total Test, Cortisol Saliva Test, Cortisol 4 Specimen Test, 4 Specimen Cortisol Test, Cortisol Free Test, Cortisol Kit Test
The Cortisol 4 Point Saliva, 4 Samples test is a diagnostic test that measures cortisol levels at four specific times throughout the day using saliva samples. Cortisol is a hormone produced by the adrenal glands that plays a crucial role in the body's stress response, metabolism, immune function, and maintaining blood pressure. This test is ordered to assess the diurnal variation of cortisol levels, which refers to the natural fluctuation of cortisol levels throughout the day.

Also Known As: Morning Cortisol Test

The Cortisol AM Test measures morning cortisol levels in the blood to assess adrenal gland function. It helps diagnose disorders like Addison’s disease, Cushing’s syndrome, and other conditions affecting stress response and hormone balance.


: Serum
Also Known As: Cortisol PM Test, Cortisol Total Test, Cortisol Test, Cortisol Blood Test
The Cortisol PM test measures the level of cortisol, a hormone produced by the adrenal glands, in the afternoon or evening. Cortisol plays a crucial role in regulating various bodily functions, including metabolism, immune response, and stress response.

: Serum
Also Known As: Cortisol Blood Test

The Cortisol Total Test measures the overall level of cortisol in the blood, a hormone produced by the adrenal glands. It helps assess adrenal function and diagnose conditions like Cushing’s syndrome, Addison’s disease, and other disorders affecting stress response.

Also Known As: DHEA Sulfate Test, Dehydroepiandrosterone Sulfate Test

The DHEA-S test measures the level of dehydroepiandrosterone sulfate in your blood. DHEA-S is a hormone produced mainly by the adrenal glands, which are small glands located above your kidneys. This hormone is important because it serves as a building block for other hormones, including estrogen and testosterone.

Also Known As: Gamma Glutamyl Transferase Test, Gamma Glutamyl TransPeptidase Test, GGTP Test, GTP Test

The Gamma Glutamyl Transferase (GGT) test measures the levels of the enzyme gamma glutamyl transferase in the blood. GGT is primarily found in the liver, bile ducts, and kidneys. The GGT test helps assess liver function and is used to diagnose and monitor liver diseases and conditions that affect the biliary system.


: Blood
Also Known As: A1c Test, HbA1c Test, Glycated Hemoglobin Test

The Hemoglobin A1c (HbA1c) test measures the average blood sugar levels over the past two to three months by assessing the percentage of glucose bound to hemoglobin in red blood cells. It is commonly used to diagnose prediabetes and diabetes, and to monitor how well blood sugar is being controlled in individuals with diabetes. Unlike a single glucose reading, the HbA1c provides a long-term view of blood sugar management.

: Serum
Also Known As: Homocysteine Cardiac Risk Test

The Homocysteine test measures the level of homocysteine, an amino acid in the blood that is influenced by vitamin B6, B12, and folate levels. Elevated homocysteine levels may increase the risk of cardiovascular disease, blood clots, and stroke, and can also be a marker for vitamin deficiencies or inherited metabolic disorders. This test is often ordered to assess heart disease risk, investigate vitamin status, or evaluate unexplained blood vessel or clotting problems.

Adrenal glands are small but play a big role in everyday life. They produce several hormones, most notably cortisol. Cortisol handles the "fight or flight" response and is how the body responds to stress.

Early Adrenal Disease Tests can track your hormone levels and determine if your hormones are out of balance. These tests are convenient and provide you with the health information you need.

Understanding the Adrenal Glands

The adrenal glands are located in the midsection of the body near the top of the kidneys. Each of the two parts of the glands—the medulla and the cortex—produces a different set of hormones.

These hormones include cortisol, aldosterone, DHEA and androgenic steroids, and epinephrine, and norepinephrine.

When the adrenal glands are not working correctly, several health issues can arise. These can include adrenal insufficiency, congenital adrenal hyperplasia, Cushing Disease, ... See more
