    It depends on what hormones are being tested for. There is T3, T4, TSH and sometimes thyroid bodies are also measured.

    The typical values, which may vary in individual cases are :

    T3 – normal values is 100 to 200 ng/dL
    T4 – normal range is 4.5 to 11.2 mcg/dL
    TSH – Normal values are 0.4 – 4.0 mIU/L

    Remember that differences in methodology among labs and the standards of measurement in your country may be different. You should discuss this with your doctor rather than attempting to decipher this on your own.
