A 4-point cortisol test, often referred to as a “diurnal cortisol test,” measures cortisol levels at four different times of the day to assess the adrenal gland’s function and the body’s stress response: after waking, before lunch, before dinner and before bed. The 4-point salivary cortisol test may be more beneficial for those who are looking to confirm the presence of abnormalities or underlying diseases through repeat testing throughout the day compared to a blood test. Ultimately, the main difference between the saliva and blood tests is that the four-point test is more diagnostic in nature, especially for conditions that affect cortisol rhythm, while the fingerprick test is more suited for general monitoring. Collect each of your saliva samples on the same day and within the time ranges specified on each tube. How to collect:
Prepare: Start with the Morning collection tube. Fill out the collection tube with your name, today’s date, and the time of your collection. Twist off the cap to open the tube.
Fill the tube halfway with saliva
Hold the tube up to your lips, and purse your lips to gently guide saliva into the opening of the tube. Fill the tube halfway, not counting bubbles.
Tightly recap the collection tube and place it into the barcoded biohazard bag.
