A member asked:

What is a "tsh reflex" test?

A doctor has provided 1 answer

Weird terminology: As best i can tell, it is just a TSH with ft4. Not sure why someone calls it "tsh reflex". Maybe the lab does the tsh, and then does the ft4 if the TSH is abnormal.

Dr Friedlander and another doctor agreed
