Voltage is analogous to pressure, so the voltage rating is the same thing as the pressure rating on a pressurized tank. If you apply too much pressure, both a capacitor and a tank will explode.
Speaking roughly, normal levels of thyroid-stimulating hormone (TSH) are in the range of 0.4 to 4.0 mIU/L. However, each laboratory and test manufacturer identifies its own normal TSH range. This is based on the test, the equipment being used, and the patients being tested.
Normal Thyroid Lab Test Reference Range Here are the normal ranges for thyroid tests according to Rush University Medical Center: TSH = 0.350 - 4.940 ÂµIU/ml. Total T3 = 0.6 - 1.6 ng/ml. Total T4 = 4.9 - 11.7 mg/dl. Free T3 = 1.7 - 3.7 pg/ml.
