Diagnosis And Evaluation
The journey toward a definitive diagnosis of adrenal failure begins with a meticulously structured evaluation. Because the symptoms overlap with many common issues, a physical exam alone is not enough. When you visit a specialist at Liv Hospital, the process starts with a detailed medical history where the clinician asks about your history of autoimmune disease and the timing of your fatigue. The goal of this evaluation is to provide objective evidence of low hormone levels and to identify whether the problem is primary or secondary.
The “gold standard” for answering how is Addison’s disease diagnosed is the ACTH stimulation test. This procedure involves measuring the response of the adrenal glands to a synthetic version of the brain’s signaling hormone.
In a healthy person, cortisol levels will jump significantly. In a patient with this condition, the damaged glands will show little to no response, providing definitive clinical proof of adrenal insufficiency.
Blood work provides a “look under the hood” at your body’s internal chemistry. While many tests are performed, specialists look for specific biochemical markers of the disease.
Since the most common cause is an autoimmune attack, the clinical diagnostic journey often includes testing for specific antibodies.
Finding these antibodies confirms that the immune system is the cause of the gland destruction. This is a vital diagnostic step at Liv Hospital because it alerts the clinician to look for other associated autoimmune conditions that the patient might develop in the future.
While blood tests confirm the hormonal failure, imaging allows clinicians to see the physical structure of the adrenal glands.
Visualizing the glands helps the medical team at Liv Hospital rule out tumors or active infections like tuberculosis that might require additional targeted treatments.
A critical part of the evaluation is the differential diagnosis, which means ruling out other conditions that look like adrenal failure.
By systematically ruling out these “lookalikes” through laboratory tests and clinical history, our expert team ensures that the diagnosis is 100% accurate, preventing the use of unnecessary medications.
In complex clinical cases where the source of the insufficiency is unclear, a more intensive test may be required.
Because this test is physically demanding, it is performed in the high-tech diagnostic suite at Liv Hospital under constant medical supervision, ensuring the patient’s safety while gathering vital data about their stress-response system.
While cortisol is the focus, the diagnosis must also evaluate the hormones that control blood pressure and minerals.
Identifying a deficiency in this area is a hallmark of primary adrenal insufficiency. This data allows the specialists to create a balanced replacement plan that addresses both energy and blood pressure stability.
Because autoimmune diseases often come in clusters, a comprehensive evaluation at Liv Hospital includes screening for associated conditions.
Treating the adrenal glands without addressing these other potential issues is only half the battle. A full diagnostic overview ensures that your whole body is supported throughout the recovery process.
At the end of the evaluation phase, you will sit down with your specialist to review all the visual findings and test results. At Liv Hospital, we believe in a transparent diagnostic process. We show you the data and explain the biological “why” behind the recommendations, ensuring you are an active participant in your care plan.

The primary tests include measuring morning cortisol and ACTH levels from a blood sample. The diagnosis is confirmed with an ACTH stimulation test (Synacthen test), which checks if the adrenal glands can produce cortisol in response to a signal.
ACTH stimulation test preparation usually involves fasting for 8-12 hours overnight. You will likely need to stop taking any steroid medications (like hydrocortisone) for at least 24 hours before the test. Always follow your specific doctor’s instructions regarding current medications.
No, the test is not painful beyond the minor discomfort of a needle prick for the blood draw and the injection. Some patients report a mild flushing sensation or warmth shortly after the ACTH injection, but this passes quickly.
The ACTH stimulation test is the gold standard and is highly accurate for diagnosing primary Addison’s disease. However, it may sometimes miss mild or recent-onset secondary adrenal insufficiency, which is why the Insulin Tolerance Test (ITT) is sometimes used as a backup.
You need advanced imaging, such as a CT scan of the adrenal glands or an MRI of the pituitary, after the blood tests confirm adrenal insufficiency. The imaging helps doctors identify the cause, such as a tumor, hemorrhage, or infection, rather than the disease itself.
