Unexplained Weight Change Tests
Experiencing unexplained weight gain or weight loss—even though your diet or routine hasn’t changed? These lab tests are designed to help you uncover what may be happening beneath the surface. This category includes lab panels that evaluate key systems known to affect body weight, including thyroid function, hormone balance, blood sugar regulation, adrenal stress response, and nutritional status. You’ll find tests that measure markers like TSH, cortisol, insulin, testosterone, estrogen, vitamin D, and more — all of which can influence unexplained shifts in metabolism, appetite, or energy level. Everything is available to purchase online, with no doctor’s visit required, and results that come quickly. Whether you’re investigating sudden weight changes or looking to provide information to your healthcare provider to rule out a possible cause, these tests offer an accessible way to get clarity and take control of your next steps.
