Understanding the "normal range." What is TSH, T4 and T3? Has your doctor checked your Vitamin D and Cholesterol?
Key Thyroid Lab Tests - T3, T4 and TSH
Helps to explain the T4, T3 and the TSH lab tests. What they mean by themselves and together.
Understanding T4 and T3
The video explains the basic function of T3. **TOTAL T4** is the amount of T4 in the blood. **FREE T4** is the amount of T4 that can be converted into T3. Not all T4 can be converted into T3 that is why most doctor's will order the Free T4 lab work. **T3 - TOTAL T3** provides the body with energy by taking an atom from T4 and converting it into energy. **RT3 - REVERSE T3** slows the body down and reduces the energy. The body takes a different atom from the T4 which puts a halt on the production of energy. ---- If the lab work results show a normal level of Free T4 but a VERY LOW FREE T3, it could indicate a problem with the body converting T4 into T3 - in which case typically a person will take a small amount of T3 along with Synthroid or Levoxyl (T4).
Cholesterol Management in Graves' Disease
"Cholesterol management is not really specific to Graves disease, but rather to the hypothyroidism which can result from the treatment of Graves disease. Hypothyroidism can lead to an elevation in serum cholesterol. Because serum cholesterol levels are affected by thyroid function, therapy for high cholesterol levels should be made once normal thyroid function has been achieved in patients with Graves disease."
