Thyroid function tests are having a wide range in the result and most of the time the lowest result also is taken for normal as well as the highest for normal. The thyroid function tests which are done normally are T3: 80-180 ng/dl T4: 4.6-12 ug/dl TSH: 0.5-6 uU/ml FT3:230-619 pg/d FT4: 0.7-1.9 ng/dl There are various views regarding the interpretation and testing as conventional and interpretive ways.in the literature. In my experience, the best form of interpretation is taken the middle level in every test and if the result is below the middle level it denotes hypo and if nearing upper limit it should be taken for hyper depending on the symptomatology and also ECG heart rate. and voltage.
If the T4 is 80 to 180 as normal range, take the difference say 100 and divide it by 2 and the resultant 50 to be added to 80 to make the middle result say 130. 180-80 = 100/2=50 +80 = 130. If the…
