Free T4 and Free T3 Thyroid Function Test
Comprehensive Thyroid Hormone Assessment
The Free T4 and Free T3 Thyroid Function Test represents a sophisticated diagnostic approach to evaluating thyroid health and metabolic function. This comprehensive panel measures the unbound, biologically active forms of thyroid hormones circulating in your bloodstream, providing clinicians with precise insights into your endocrine system’s performance and overall metabolic regulation.
What This Test Measures
Our advanced thyroid panel specifically evaluates:
- Free Thyroxine (FT4): The unbound, active form of T4 hormone that regulates metabolism, body temperature, and energy production
- Free Triiodothyronine (FT3): The biologically active form of T3 hormone that directly influences cellular metabolism and energy utilization
Who Should Consider Thyroid Testing
This comprehensive thyroid panel is recommended for individuals experiencing:
- Unexplained fatigue and low energy levels
- Significant weight changes without dietary modifications
- Temperature sensitivity and cold intolerance
- Hair loss, dry skin, or brittle nails
- Mood changes, depression, or anxiety
- Menstrual irregularities or fertility concerns
- Heart palpitations or rapid heartbeat
- Muscle weakness and joint pain
- Difficulty concentrating or brain fog

Understanding Your Test Results
Your Free T4 and Free T3 results will fall within specific reference ranges that indicate optimal thyroid function:
Normal Results
When both Free T4 and Free T3 levels fall within established reference ranges, this typically indicates normal thyroid function and balanced hormone production.
Elevated Levels
High Free T4 and Free T3 levels may suggest hyperthyroidism, Graves’ disease, thyroiditis, or excessive thyroid medication. Symptoms often include weight loss, anxiety, rapid heartbeat, and heat intolerance.
Low Levels
Reduced Free T4 and Free T3 levels typically indicate hypothyroidism, Hashimoto’s thyroiditis, pituitary gland disorders, or iodine deficiency. Common symptoms include fatigue, weight gain, depression, and cold sensitivity.
