Description
The Free T3 test measures the active form of the thyroid hormone T3 in your blood. It’s used to diagnose hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid) and to monitor ongoing thyroid treatment.
Why It Matters:
- Detects thyroid imbalances that can affect energy, metabolism, and overall health
- Helps monitor treatment effectiveness for thyroid disorders
- Low Free T3 levels, if left untreated, may contribute to serious conditions like heart disease or diabetes
Possible Symptoms of Thyroid Issues:
- Unexplained weight gain or loss
- Rapid or irregular heartbeat
- Hair thinning or loss
- Dry skin
- Fatigue or mood changes
- Menstrual irregularities in women
Fasting not required.
This test provides vital insight into your thyroid health and how well your body is converting and using thyroid hormones.
