 How to diagnose Adrenal Insufficiency and Addison's Disease ? 
 After Addisons disease is diagnosed, health care providers may use the following tests to look at the adrenal glands, find out whether the disease is related to TB, or identify antibodies associated with autoimmune Addisons disease.
                
- Ultrasound of the abdomen. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images; a patient does not need anesthesia. The images can show abnormalities in the adrenal glands, such as enlargement or small size, nodules, or signs of calcium deposits, which may indicate bleeding.   - Tuberculin skin test. A tuberculin skin test measures how a patients immune system reacts to the bacteria that cause TB. A small needle is used to put some testing material, called tuberculin, under the skin. A nurse or lab technician performs the test in a health care providers office; a patient does not need anesthesia. In 2 to 3 days, the patient returns to the health care provider, who will check to see if the patient had a reaction to the test. The test can show if adrenal insufficiency could be related to TB.  To test whether a person has TB infection, which is when TB bacteria live in the body without making the person sick, a special TB blood test is used. To test whether a person has TB disease, which is when TB bacteria are actively attacking a persons lungs and making the person sick, other tests such as a chest x ray and a sample of sputumphlegm that is coughed up from deep in the lungsmay be needed.   - Antibody blood tests. A blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. The blood test can detect antibodiesproteins made by the immune system to protect the body from foreign substancesassociated with autoimmune Addisons disease.
                
After secondary adrenal insufficiency is diagnosed, health care providers may use the following tests to obtain a detailed view of the pituitary gland and assess how it is functioning:
                
- Computerized tomography (CT) scan. CT scans use a combination of x rays and computer technology to create images. For a CT scan, the patient may be given a solution to drink and an injection of a special dye, called contrast medium. CT scans require the patient to lie on a table that slides into a tunnel-shaped device where the x rays are taken. An x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia. A CT scan can show size and shape of the pituitary gland to find out if an abnormality is present.   - Magnetic resonance imaging (MRI). MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. An MRI may include the injection of contrast medium. With most MRI machines, the patient lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some machines are designed to allow the patient to lie in a more open space. A specially trained technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia, though people with a fear of confined spaces may receive light sedation, taken by mouth. MRIs can be used to produce a three-dimensional (3-D) image of the hypothalamus and the pituitary gland to find out if an abnormality is present.   - Hormonal blood tests. Hormonal blood tests can assess how the pituitary gland is functioning and its ability to produce other hormones.
