How endocrinologists test adrenal function usually starts with blood work. The two most common methods are the ACTH stimulation test and cortisol panels. Imaging for testing adrenal function may follow if a scan is needed. Together, these tools reveal whether your adrenal glands are working the way they should.
Your body has been sending signals that something is off. Maybe you feel drained all the time, or your weight keeps changing without reason. These symptoms are frightening when the cause stays hidden. Very often, the answer sits in two small glands above your kidneys.
This guide walks you through how endocrinologists test adrenal function, step by step. You will learn what each test looks for, what to expect during the process, and what happens after a diagnosis. Knowing what lies ahead can ease the worry that comes with the unknown. You are not alone, and clear answers are within reach.
How Endocrinologists Test Adrenal Function
An endocrinologist uses a few reliable tools to check adrenal health. Each one measures a different part of the picture. Together, they show whether your glands make the right amount of key hormones.
ACTH Stimulation Test
The ACTH stimulation test checks how well your adrenal glands respond to a signal. Your doctor gives you a small dose of a hormone called ACTH. Then they measure your cortisol before and after.
Healthy glands raise cortisol in response. If the levels stay low, it can point to an adrenal problem. This test is a common way to confirm adrenal insufficiency.
Cortisol Panels
Cortisol panels measure how much cortisol your body makes. Cortisol helps control stress, blood sugar, and blood pressure. Too much or too little can cause real trouble.
Your doctor may check cortisol at different times of day, since levels shift from morning to night. Blood, saliva, or urine samples can all be used. These panels give a clear view of your hormone balance.
Imaging for Testing Adrenal Function
Sometimes blood tests are not enough on their own. Imaging for testing adrenal function lets your doctor look at the glands directly. A CT scan or MRI can spot a tumor, growth, or unusual size.
Imaging often follows abnormal blood results. It helps confirm the cause and guide the next steps. Not everyone needs a scan, so your endocrinologist will decide based on your results.
What to Expect During Testing
The unknown is often the hardest part. Knowing the steps ahead can calm those nerves. Most adrenal tests are simple and low risk.
- Blood draws: Quick and routine, done in a clinic or lab.
- ACTH stimulation test: Takes about an hour, with a short wait between blood draws.
- Imaging: Painless scans that usually last under an hour.
Your care team will explain each step before it begins. You can ask questions at any point. Clear communication is part of good care.
Treatment Paths After Diagnosis
A clear diagnosis brings relief. Once your endocrinologist knows the cause, treatment can begin. The goal is always to bring your hormones back into balance.
- For low cortisol: Daily hormone replacement to restore what your body lacks.
- For high cortisol: Medication to lower levels, or surgery to remove a tumor.
- Ongoing support: Regular check-ins to keep your hormone levels steady.
Most people respond well to care and return to daily life with confidence. The right plan makes a real difference.
