My mother has hypothyroidism and these are her recent private blood results. We haven't got the antibody results yet. Her TSH was 4.3 a month ago and then she was put on an extra 25 mg of thyroxine so now she takes 125mg. Do these results look normal? Is it even possible for TSH to drop so low so quickly?
