I just received my lab results for my thyroid and it marked at 1.57.  Does that mean it is normal?  I emailed my doctor about this but wanted to see if anyone here can assist me. Last year, I was diagnosed with under active thyroid, so I wanted to better understand my results. Im currently taking 500 mg of levothyroxine.

    Hi Stephanie 22448

    Is your dosage 50mg ? Ive never heard of anyone on 500mg. If it is 500mg how long have you been on this dosage?

    Is 1.57 your TSH reading,

    'The normal range of TSH levels is 0.4 to 4.0 milli-international units per liter. If you're already being treated for a thyroid disorder, the normal range is 0.5 to 3.0 milli-international units per liter. A value above the normal range usually indicates that the thyroid is underactive. This indicates hypothyroidism.20 Jan 2016'

      Wait so it means I'm still hypo? 😩 For some reason I thought it turn back to normal.

      1.57 means that your TSH is within normal range and you are on correct dosage of Thyroxine

      You are still hypothyroid as it is taking the dosage to keep you within normal range
