How to Prepare for a Cortisol Saliva Test

Cortisol is a hormone that is produced by the adrenal glands. The hormones plays an integral role in many of the body's metabolic functions, including blood pressure levels, glucose management and building muscle. Cortisol levels can be measured in three bodily fluids: blood, urine, and saliva. A few easy steps can help you prepare for a cortisol saliva test.

Instructions

• 1

  Read the directions that are included in the cortisol saliva test kit you will be using. You might be given the kit from a lab or might need to purchase the kit from a medical supply store. Be sure all of the parts that are listed on the instructions are included with the kit.

  Find out from your doctor when you should take the cortisol saliva test. According to the American Association for Clinical Chemistry, most people experience their lowest level of cortisol between 11 p.m. and midnight, and might be required to test their saliva at this time. Prepare for the test by resting early in the evening if you are not usually awake late at night.

  Relax prior to the cortisol saliva test, and try to refrain from any stressful activity. Cortisol levels rise when you are stressed, Dr. David Zava said in an interview in the John R. Lee, M.D. Medical Letter reprinted in Virginia Hopkins Health Watch. Try to remain calm to secure an accurate reading for the test.

  Perform the test as required. You will chew on piece of cotton material for a couple of minutes until it is saturated with your saliva. Place the cotton in the test tube included with your kit. Ready the test kit for delivery to the lab.
