Reverse T-3 (rT3) is a thyroid hormone metabolite test supplied by Nutripath. This test measures levels of reverse T-3, which can provide additional insight into thyroid hormone activity beyond standard TSH and free T4 tests. The result helps healthcare practitioners better understand thyroid function and assist in complex cases involving metabolism and thyroid hormone regulation. Testing is done via a simple blood collection and processed by specialist laboratories to ensure accurate and reliable results.
