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.
