Salivary Cortisol, 2 Samples
Late-night cortisol that loses its normal dip is the first clue to Cushing syndrome.
Consider this test if:
- Weight gain, easy bruising, purple stretch marks, high blood pressure, or muscle weakness suggesting cortisol excess
- Screening for endogenous Cushing syndrome with a convenient at-home sample
- Monitoring for recurrence of Cushing disease after pituitary surgery
- Tracking treatment response during medical therapy for Cushing disease
- Suspected cyclic Cushing syndrome requiring multiple samples over time
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
Timing is the whole point: collect late at night, usually around 11 pm or when instructed, since the test depends on cortisol being at its low point. Do not eat, drink, or brush your teeth shortly before collecting, and avoid foods or supplements with licorice. Keep a normal day-night routine in the days before testing; this test is not valid for shift workers or anyone without a regular sleep-wake cycle. Use both Salivette devices as directed and keep samples refrigerated until return.

What this test is for
Cortisol follows a circadian rhythm: it peaks in the morning and falls to its lowest point late at night. This test measures cortisol in saliva at two collection points, typically late at night, when a healthy level should be at its nadir. The main use is screening for endogenous Cushing syndrome, since people with it lose that late-night low, and two or more elevated late-night results help confirm it. Saliva is easy to collect at home over multiple nights, which makes it well suited to catching cyclic Cushing syndrome and to monitoring for recurrence after pituitary surgery or during medical therapy. Levels can also be raised by obesity, heavy alcohol use, depression and other psychiatric conditions, and PCOS, so results are read against your clinical history.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
