Supplement Overview

Item Catalog Number: LC001156
Click for Blood Testing Information

T3 uptake is an indirect measurement of the available binding sites for the thyroid stimulatory hormones from the brain. T3 uptake is not a measurement of T3 and should never be used alone. It is best used in conjunction with T4.

T3 uptake can be abnormal with thyroid dysfunction, malnutrition, and kidney disease. Additionally, abnormal T3 uptake can be seen with use of oral contraceptives and hormone prescriptions such as testosterone and estrogen.

Fasting is not required. Take all medications as prescribed. Do not take your supplements the day of the test. This test is not included in any Life Extension panel.

The blood test services are for informational purposes only. It is not the intention of National Diagnostics, Inc, Life Extension, and DR Vitamin Solutions to provide specific medical advice but rather provide users with information to better understand their health. Specific medical advice including diagnosis and treatment will not be provided. Always seek the advice of a trained health professional for medical advice, diagnosis, or treatment.

Both the physician and the test laboratory are independent contractors with whom National Diagnostics, Inc makes arrangements for your blood tests. Neither National Diagnostics, Inc, Life Extension, nor DR Vitamin Solutions will be liable any acts or commissions of the physician, the testing laboratory, or their agents or employees.
