Sleep quality is directly affected by several measurable biomarkers. Thyroid dysfunction (TSH) can cause insomnia or excessive sleepiness. Cortisol dysregulation — tested with both AM and PM draws — reveals whether your natural cortisol rhythm is disrupted, a common cause of difficulty falling asleep or waking at 3 AM. Iron deficiency (Iron Panel + Ferritin) is the leading cause of restless leg syndrome. Low magnesium impairs GABA activity and muscle relaxation. Vitamin D deficiency is associated with shorter sleep duration and poorer sleep quality. Blood sugar instability (A1c) can cause nighttime awakenings from nocturnal hypoglycemia. This panel identifies the treatable conditions most often responsible for sleep problems.
Sleep-disruption screen: Cortisol AM + PM (diurnal rhythm), TSH (thyroid sleep impact), Iron Panel + Ferritin (restless legs), Vitamin D, Magnesium, A1c (metabolic context). The most common treatable causes of chronic insomnia or poor sleep quality.
Anyone with chronic insomnia, frequent night-waking, restless legs, fatigue despite adequate sleep duration, or sleep-quality changes during menopause/perimenopause.

What can throw off this result
Physician-reviewed “Before your test” pages — what each factor does, for how long, and what to do about it.
A Sleep Health Panel costs $129.99 at TestWell — $135.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
| Where you order | Price | One test, all-in | Notes |

Cortisol AM and PM (assesses HPA-axis stress rhythm), TSH (hyperthyroidism is a classic cause of insomnia), Iron Panel + Ferritin (low iron/ferritin causes restless legs and disrupts sleep architecture), Vitamin D and Magnesium (deficiencies impair sleep quality), plus A1c for metabolic context.
TestWell charges $129.99 — vs $279-$349 at Quest Direct and $400-$800 at integrative sleep clinics.
Yes for the AM draw (8 hours fasting, no caffeine before draw). PM cortisol draw is non-fasting; we'll send a kit with timing instructions if added.
No — sleep apnea requires a sleep study (in-lab polysomnography or at-home WatchPAT). This panel rules out the metabolic/hormonal contributors to poor sleep. If your sleep is still poor with normal labs, see a sleep medicine specialist.
Low ferritin (<50 ng/mL) is the most common reversible cause of restless legs syndrome and is implicated in fragmented sleep architecture. Often missed because standard CBC can be normal.
Sleep Health Panel results are typically ready in 3–5 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
Time of day, recent illness and recent blood donation can change a Sleep Health Panel result without anything being wrong. Time of day can shift Cortisol, TSH and Iron — A.M. cortisol at 7–9 a.m.; P.M. cortisol as the lab specifies. Recent illness can raise Ferritin and can lower Iron — wait 2 weeks — illness can mask iron deficiency. Recent blood donation can lower Ferritin and Iron and can raise TIBC — tell the clinician the donation date; a low ferritin soon after donating is expected, not a mystery. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
Order the Sleep Health Panel online from TestWell for $129.99 (plus a $6 per-order lab processing fee) — no doctor's visit, referral or insurance needed. A licensed physician authorizes the order, then you walk into any Quest or Labcorp patient service center near you for the draw (the lab locator on our site lists the closest ones by ZIP code), and results arrive in 3–5 business days.
