Essential thyroid function screening panel including TSH, total T4, and total T3. Provides fundamental assessment of thyroid hormone production and pituitary-thyroid axis function. Ideal for initial thyroid screening, routine monitoring, and detecting common thyroid disorders.
Your thyroid sets the pace for your metabolism, influencing energy production, body temperature, heart rate, and how efficiently you convert food into fuel. This panel measures the three markers that form the core of thyroid assessment: TSH is the pituitary signal that tells your thyroid how hard to work, while Total T4 and Total T3 reflect the actual circulating hormones your body produces in response. Looking at them together is far more informative than any single value—for example, a high TSH alongside low T4 points to a different picture than a normal TSH with altered T3, helping distinguish where in the pituitary-thyroid axis a change may be occurring. From these results you can learn whether unexplained fatigue, changes in weight, cold or heat intolerance, or shifts in energy warrant a conversation with your clinician about thyroid function. Ordering these three markers as one panel means a single blood draw and a coordinated snapshot, rather than piecing together individual tests that only tell part of the story.
For athletes & active people
For athletes, thyroid hormones directly affect metabolic rate, energy availability, and recovery, and prolonged high training loads or low energy intake can influence thyroid signaling over time. This panel offers a useful baseline check when training performance, recovery, or energy levels feel off in ways that nutrition and sleep alone don't explain, giving you objective data to discuss with a healthcare provider.
