A saliva test designed to measure the levels of the hormone cortisol, taken four times in a 24-hour period (morning, noon, evening, and nighttime). The adrenal gland produces the hormone cortisol in response to stress. Prolonged high cortisol production can lead to chronic fatigue, "adrenal burnout" and other health problems. This test samples cortisol levels at 4 times throughout a day, revealing a complete daily cycle.
Same as the Diurnal Cortisol 4x Stress test, which measures a complete daily cortisol cycle, plus DHEA-S which is also an indicator of adrenal health. Low DHEA-S can lead to chronic fatigue and weight gain. High DHEA-S levels can promote androgen (male) features in women, and is an indicator of adrenal tumors and PCOS.
The best overall assessment for your thyroid. Combines the four most clinically useful thyroid function tests, giving a more thorough assessment compared with monitoring TSH alone. Measures fT4, fT3, TSH, TPO.
The test includes 6 collections of cortisol throughout the day. To capture this response, three – rather than one – morning saliva collections are needed to properly chart the diurnal cortisol curve within 60 minutes of awakening.
