Coritsol Blood Test

Coritsol Blood Test; The Stress Hormone

The hormone cortisol can be tested through a Cortisol blood test. This simple blood testing series can detail disorders or problem functioning of the adrenal glands, as well as the pituitary gland. The levels of the hormone rise and fall during the day; however there are other factors that can lead to abnormal levels that should be monitored. Because cortisol plays a vital role in the body’s metabolism and managing stress it is important to have a Cortisol Blood test to ensure proper functioning.

When The Cortisol Blood Tests Are Ordered

This blood test is commonly ordered when a physician suspects problems with either the pituitary or adrenal glands. Either of the glands may not be producing hormones in correct numbers, therefore causing other health problems. Other suspected disorders such as Cushings Syndrome are common reasons for ordering the blood test as well. Certain medications can affect cortisol levels and physicians will use the blood test to monitor them as well. It is notable to mention that some prescription medications, as well as over the counter medications can affect the cortisol blood test.

Normal Range For The Blood Testing

The range of cortisol differs between the time of day and age groups. It is common for the levels to be elevated in the morning and then drop throughout the day. Normal blood test levels for an adult in an AM test are between 5 and 23 mcg/dL, and PM tests normal ranges are between 3 and 13 mcg/dL. The normal range for a child in an AM test are between 3 and 21 mcg/dL, and 3 to 10 mcg/dL for an PM test. Newborns range from 1 to 24 mcg/dL, at any time of the day.
