What Are Thyroid Panel Tests?
Thyroid panel tests measure hormones that control your body's metabolism, energy levels, and temperature regulation. TSH (Thyroid Stimulating Hormone) is produced by the pituitary gland to regulate thyroid function. T4 (Thyroxine) is the main hormone produced by the thyroid gland. T3 (Triiodothyronine) is the active form of thyroid hormone that directly affects metabolism.
These hormones work together to regulate heart rate, body temperature, energy production, and weight management. Our AI-powered report interpreter online analyzes these complex interactions, providing comprehensive thyroid function insights and personalized optimization strategies for metabolic health.
TSH: The Master Controller
TSH acts as the body's thermostat for thyroid function. When thyroid hormone levels drop, TSH increases to stimulate more production. When levels are high, TSH decreases. This feedback loop is crucial for maintaining metabolic balance and detecting thyroid disorders early.
- Primary screening tool: First test ordered for suspected thyroid problems
- Sensitive indicator: Changes before T3 and T4 in early disease
- Treatment monitoring: Tracks response to thyroid medications
- Inverse relationship: High TSH indicates low thyroid function (hypothyroidism)
- Early detection: Identifies subclinical thyroid dysfunction
T4: The Storage Hormone
T4 (thyroxine) makes up about 90% of thyroid hormone production but is relatively inactive. It serves as a reservoir that's converted to the active T3 hormone as needed. Free T4 measures the unbound, biologically available portion that can enter cells.
Key Functions
Hormone storage, T3 conversion precursor, metabolic regulation
Imbalance Signs
Fatigue, weight changes, temperature sensitivity, mood issues
T3: The Active Powerhouse
T3 (triiodothyronine) is the most metabolically active thyroid hormone, about 3-4 times more potent than T4. Free T3 directly controls cellular metabolism, energy production, and body temperature. It's the hormone that actually drives metabolic processes at the cellular level.
Metabolic Effects
Energy production, protein synthesis, fat burning, heart rate regulation
Clinical Importance
Detects T3 toxicosis, peripheral conversion issues, optimal function
