Lab tests & results

The American Association of Clinical Endocrinologists changed the normal value range for TSH levels. The normal range was 0.5 to 5.0. Numbers above 5.0 were considered hypothyroid, and below 0.5 was considered hyperthyroid. The new values are 0.3 to 3.0, with anything above 3.0 being hypothyroid.

There are many labs today that continue to use the old numbers. The blood test is not exhaustive. If your TSH, Free T4, and Free T3 all show normal, the presence of antibodies indicate an autoimmune disorder.
