A member asked:

Is it true that in united states, the tsh from thyroid is in normal range between 0.2 and 3 ? more than that could be too much for a boy ?

A doctor has provided 1 answer

It depends on lab: Most labs publish their normal ranges along with patient results. Normal ranges vary from lab to lab due to different testing methods. If your lab is using the ultrasensitive TSH test, here is a good reference broken down by patient age. http://www.questdiagnostics.com/hcp/intguide/endometab/endomanual_atoz_pdfs/tsh_ultrasensitive.pdf.
