Question: What Are Normal ACTH Test Results?

What should my cortisol level be?

Normal cortisol levels are usually highest early in the morning and lowest about midnight.

Normal ranges vary depending on the type of test.

For most tests, normal ranges are: 6 to 8 a.m.: 10 to 20 micrograms per deciliter (mcg/dL).

What are the symptoms of high ACTH?

Why do I need an ACTH test?Weight gain.Buildup of fat in the shoulders.Pink or purple stretch marks (lines) on the abdomen, thighs, and/or breasts.Skin that bruises easily.Increased body hair.Muscle weakness.Fatigue.Acne.

What does too much ACTH do?

With Cushing disease, the pituitary gland releases too much ACTH. ACTH stimulates production and release of cortisol, a stress hormone. Too much ACTH causes the adrenal glands to make too much cortisol. Cortisol is normally released during stressful situations.

What causes high levels of ACTH?

High levels of ACTH may be caused by: Emotional or physical stress (such as recent surgery or severe pain). Diseases such as Addison’s disease (failure of the adrenal glands), Cushing’s disease (a tumor of the pituitary gland), or a tumor outside the pituitary (such as in the lung).

What is the normal range for morning levels of ACTH?

Normal Results Normal values for a blood sample taken early in the morning are 9 to 52 pg/mL (2 to 11 pmol/L). Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or may test different specimens. Talk to your doctor about the meaning of your specific test results.

How long do ACTH test results take?

You will typically get the results of your ACTH stimulation test in one to two weeks.

What does a low ACTH result mean?

A decline in the concentration of ACTH in the blood leads to a reduction in the secretion of adrenal hormones, resulting in adrenal insufficiency (hypoadrenalism). Adrenal insufficiency leads to weight loss, lack of appetite (anorexia), weakness, nausea, vomiting, and low blood pressure (hypotension).

What is the normal range of ACTH?

ACTH is measured in picograms per milliliter (pg/mL). Test results are influenced by the time of day the test was done. Normal results are: Adults: 6-76 pg/ml (1.3-16.7 pmol/L)

What does low cortisol feel like?

Low levels of cortisol can cause weakness, fatigue, and low blood pressure. You may have more symptoms if you have untreated Addison’s disease or damaged adrenal glands due to severe stress, such as from a car accident or an infection. These symptoms include sudden dizziness, vomiting, and even loss of consciousness.

What cortisol level indicates Addison’s disease?

A low sodium, high potassium or low cortisol level may indicate Addison’s disease. You may need to see a hospital hormone specialist (endocrinologist) for your blood to be tested for the following: a low level of the hormone aldosterone. a high level of adrenocorticotrophic hormone (ACTH)

Is ACTH high or low in Addison’s disease?

The normal response is a peak in ACTH levels followed by a peak in cortisol levels. People with Addison disease (underactive or damaged adrenal glands) produce a high level of ACTH but no cortisol. People with secondary adrenal insufficiency have absent or delayed ACTH responses.

How do you test for ACTH deficiency?

Blood testsACTH stimulation test. The ACTH stimulation test is the test used most often to diagnose adrenal insufficiency. … Insulin tolerance test. … CRH stimulation test. … Antibody blood tests. … Computed tomography (CT) scan. … Tests for TB. … Magnetic resonance imaging (MRI)

What are normal levels of ACTH and cortisol?

Normal ranges for ACTH are fairly broad and like cortisol levels are time-dependent. They also vary from assay to assay. A typical normal range for an 8AM sample using the new assays is 10 to 50 picograms per milliliter (pg/ml); levels are usually less than 20 pg/ml at 4 PM and less than 5-10 pg/ml at midnight.

What is a high level of ACTH?

An increased ACTH result can mean that a person has Cushing disease, Addison disease, overactive, tumor-forming endocrine glands (multiple endocrine neoplasia), or ectopic ACTH-producing tumors. A decreased ACTH result can be due to an adrenal tumor, steroid medication, or hypopituitarism.

What level of cortisol is considered low?

When a technician carries out the cortisol level test between 6 a.m. and 8 a.m., the results will typically be within the range of 10–20 micrograms per deciliter (mcg/dL) in a healthy person. A doctor will generally consider measurements outside of this range to be abnormally low or high.
