Cortisol test — at-home AM cortisol & adrenal panel for women.
Cortisol is your master stress hormone — and the first hormone to misbehave when sleep, perimenopause or chronic stress collide. A single morning blood draw between 7–9am gives the cleanest read on whether your HPA axis is running too hot or too flat.
Her Form draws AM cortisol at your home, runs it alongside DHEA-S, full thyroid, sex hormones and metabolic markers, then our health specialists reads it against your symptoms (sleep, energy, weight, mood, cycle).
Signs your cortisol may be off
- ✺Wired-but-tired — exhausted by 3pm, second-wind at 10pm
- ✺Waking at 2–4am and unable to fall back asleep
- ✺Belly weight that won't shift despite training and diet
- ✺Salt or sugar cravings, low blood pressure on standing
- ✺Anxiety, racing thoughts, short fuse
- ✺Period changes layered on top of burnout
- ✺Hair shedding, brittle nails, slow wound healing
What an AM cortisol blood test actually shows
Cortisol follows a daily rhythm — high at waking, falling through the day, lowest at midnight. A 7–9am venous draw captures the peak. Too high = stress system stuck on; too low = adrenal output flattened.
Cortisol alone is a snapshot, not a story. Pairing it with DHEA-S (adrenal reserve), TSH, free T3/T4 and sex hormones is how our health specialists separates 'just stressed' from perimenopause, thyroid drag or genuine HPA-axis dysregulation.
How to test cortisol levels (at home)
Book the home draw between 7–9am. Don't exercise that morning, don't drink coffee before the draw, sleep as normally as possible the night before.
If you're on hydrocortisone or oral steroids, tell us when you book — those mask the result. Birth control raises total cortisol-binding globulin and can inflate the number.

How to test cortisol levels?+
The gold-standard is an 8am venous blood draw. Her Form sends a nurse to your home between 7–9am, samples go straight to our accredited lab, and our health specialists reviews the result alongside DHEA-S, thyroid and sex hormones.
How to test cortisol levels at home?+
Two routes: (1) an early-morning blood draw at home (most accurate single number) — what Her Form does; or (2) a four-point saliva curve across the day (cheaper, less precise). For women in perimenopause or with burnout symptoms, the AM blood draw plus DHEA-S is the panel our health specialists recommends.
Can you test cortisol levels?+
Yes — cortisol is one of the most commonly tested adrenal markers. You don't need a GP referral with Her Form; we draw at home, the lab runs it, our health specialists writes up the result.
How to test for high cortisol?+
An AM serum cortisol above the upper end of range, especially paired with low DHEA-S, central weight gain, poor sleep and high blood sugar, points toward elevated cortisol. Persistent high cortisol warrants follow-up (24-hour urinary cortisol or low-dose dex suppression) — our health specialists flags when a referral is indicated.
What does a cortisol test show?+
It shows the total cortisol your adrenal glands are producing at that moment. Read in context (time of day, cycle, medications, symptoms, DHEA-S, thyroid), it tells you whether your stress axis is over-firing, under-firing or healthy.
Will birth control or HRT change my cortisol result?+
Combined oral contraceptives raise cortisol-binding globulin, which inflates total cortisol. HRT can shift it too. Our health specialists factors this in when reading your result.
