About Total T4 Test | Thyroxine Blood Test - Thyroid Testing in Owensboro
Thyroxine is a hormone the thyroid gland releases to help regulate metabolism, heart rate, body temperature, and many other processes. The Total T4 test reports both the protein-bound and free portions of this hormone in a blood sample.
The thyroid gland produces two main hormones: thyroxine (T4) and triiodothyronine (T3). T4 is the more abundant of the two, and much of it travels through the blood attached to carrier proteins. The Total T4 test measures all of the thyroxine present, whether bound to proteins or circulating freely.
Because T4 influences the pace of cellular activity throughout the body, abnormal levels can produce noticeable effects. Elevated total thyroxine may accompany an overactive thyroid, while low levels may accompany an underactive thyroid. Results are usually interpreted alongside other thyroid markers, such as TSH and T3, to build a fuller picture.
The test involves a routine blood draw, and the sample is analyzed in a laboratory. Turnaround is typically one to three business days. Preparation instructions should be followed as provided by the laboratory performing the collection.
