Hi,
At least 1 miu/l. See units, sometimes they report in other units too , yes titration of doses accordingly done but Overt"
hypothyroidism is diagnosed when the
TSH is elevated and the T4 is low. "Subclinical" hypothyroidism is diagnosed when the TSH is elevated but the T4 is normal.
Hence, T4 is also important, (eat healthy food like antioxidants
multivitamin for week in month, fruits juices, steamed vegetables amla,
aloe vera, basil etc., are good in thyroid problems, in one research shown by breathing exercises like sky technique,
yoga, normalized thyroid hormones in month along with regular medical checkup and treatment, you can also combine all these).
Take care. Hope I have answered your question. Let me know if I can assist you further.
