A 3-point cortisol test, often referred to as a “diurnal cortisol test,” measures cortisol levels at three different times of the day to assess the adrenal gland’s function and the body’s stress response. The 3-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 three-point test is more diagnostic in nature, especially for conditions that affect cortisol rhythm, while the fingerprick test is more suited for general monitoring.Method: saliva
