Thyroid Panel (TSH & FT4)
Evaluation of thyroid-stimulating hormone and free thyroxine.
Clinical Relevance
The thyroid gland controls basal metabolic rate, body temperature, cardiovascular activity, and energy levels. Measuring TSH alongside FT4 helps differentiate early primary hypothyroidism from transient changes.
Why It Varies
Impacted by autoimmune reactions, severe caloric restriction, stress, selenium/iodine mineral deficiencies, and system recovery cycles.
Longevity & Lifestyle Pointers
- Ensure sufficient intake of trace minerals, particularly Selenium and Zinc.
- Avoid extreme or prolonged low-calorie dieting, which can suppress active hormone conversion.
- Implement stress-reduction techniques to manage high cortisol, which blocks thyroid pathways.
Clinical Governance & Disclaimer
If TSH is elevated and FT4 is low, this indicates underactive thyroid performance. All biomarker results are signposted to qualified practitioners for medical evaluation when abnormal.
