In a thyroid function test (TFT), "AM" typically refers to the time of day the blood sample is taken, usually in the morning. This is important because thyroid hormone levels can fluctuate throughout the day. The key components measured in a TFT include Thyroid-Stimulating Hormone (TSH), Free T4, and sometimes Free T3, which help assess thyroid function and diagnose conditions like hypothyroidism or hyperthyroidism. An abnormal result can indicate an underactive or overactive thyroid.
