This drop in TSH is an attempt to return circulating thyroid hormone levels to normal. So, a test to measure the amount of TSH in your system will usually show lower than normal TSH when the thyroid is overactive. So, in general, LOWER TSH = OVERACTIVE THYROID / HYPERTHYROIDISM.

This test measures the level of thyroid stimulating hormone (TSH), a kind of master hormone that regulates the work of the thyroid gland. If TSH is high, it typically means that your thyroid function is too low (hypothyroid).
