Question: is a tsh level of 2.7 normal?
Answer: In most clinical laboratories in the U.S., the “normal” reference range for the TSH is 0.4 to 4.50 mIU/liter. If the TSH is above the “normal” reference range, this may indicate hypothyroidism. In hyperthyroidism, the TSH is below the “normal” range or not detected at all.
