The normal ranges of T3, T4 and TSH is actually depends on the type of assay and how the test is done in different labs. In most of the labs what they use is the nanograms per ml or micrograms per deciliter for T3 and T4 and for TSH are microintrernational units per ml.

Understand what your thyroid lab tests are telling you: 1. High TSH, normal T4, normal T3 = This is the pattern we've been discussing in this video and will usually present with hypothyroid symptoms. 2. High TSH, normal T4, low T3 = This pattern may be an indication that you are having issues with thyroid conversion and most often presents with hypothyroid symptoms. 3. Normal TSH, low T4, low T3 = This pattern is usually what is seen in those with chronic illness and in those who are taking mult
