T3 Blood

T3 Tests are performed to assess thyroid function. They are used to diagnose thyroid disorders like hyperthyroidism (elevated T3 levels) and hypothyroidism (low T3 levels). T3 Tests are also used to monitor the effectiveness of thyroid treatments.

The T3 Test involves drawing a blood sample, usually from a vein in the arm. The collected blood is then sent to a laboratory for analysis. Results are typically available within a few days.

Normal T3 levels typically fall within the laboratory reference range, which is usually between 80 to 200 nanograms per deciliter (ng/dL). It's important to note that reference ranges may vary slightly between different laboratories.
