Few possibilities: These labs seem at odds, with TSH suggesting overactive thyroid and ft4 underactive thyroid. Free T4 tests can be inaccurate in some people who have interfering substances present. Another possibility is a tumor in the pituitary secreting too much TSH resulting in thyroid overactivity, and high thyroid hormone levels. This is quite rare, however. Your doctor can help sort this out. ...Read more
Tsh 5.4, T4 7.6 plus low red blood cell count, high ldl, hdl, vldl & triglycerides r high. What other test can tell me what caused my thyroid to stop?
It doesn't matter: A test of antithyroid antibodies may suggest that thyroiditis caused your decline in thyroid level, but it doesn't matter since the appropriate therapy is brand name T4 replacement, no matter what the cause.

An old women with very low f.T4=.2 and high level of tsh>100 and tpo = 471 and ldh = 1121 and ESR = 50 what is the most likely cause for that ?
Hypothyroidism: Sed rate is not the key here. She probably has autoimmune thyroiditis / hashimoto's because of anti-thyroid peroxidase antibodies. She needs to be treated for her hypothyroidism or it will be a disaster. The high ldh might be due to concurrent pernicious anemia, folate deficiency, or any of a few hundred other possibilities. The key is as usual the history and physical exam. ...Read more
