How to Collect the Sample for a Saliva Cortisol Test

Cortisol is the most abundant circulating steroid and the major glucocorticoid secreted by the adrenal cortex.  It helps the body use sugar (glucose) and fat for energy (metabolism). It also helps the body manage stress. Cortisol testing helps diagnose Cushing syndrome, primary and secondary adrenal insufficiency as well as other malfunctions of the adrenal and pituitary glands.

The following are collection guidelines of saliva cortisol test.

• Wash your hands with soap and warm water. Dry them well with a clean towel.
• Remove the top cap of the tube. You will see the swab.
• Place the swab directly into your mouth by tipping the tube so that the swab falls into your mouth.
• Do not touch the swab with your fingers.
• Keep the swab in your mouth for 2 minutes. Roll the swab around in your mouth. (If you cannot roll the swab, keep it under your tongue.)
• Do not chew the swab.
• Put the swab back into the container without touching the swab.
• Put the cap back on the tube. Make sure it is closed tightly.
• Write your name, date of birth and the time the sample was collected on the label.
• Bring the sample back to your clinic the next day.
