    TSH reflexive standard range: 0.27 - 4.2 uU/mL
    T4 Free standard range: 0.9-1.7 ng/dL

    (obtained the numbers from my lab results that my doctor has online)

    Different labs use different ranges. I go to LabCorp. Their normal range for free T4 is 0.82-1.77. and the normal range for TSH is 0.45-4.50.
