General description

Reverse T3 or rT3 is a biologically inactive form of the thyroid hormone T3 and is produced in the body particularly during periods of stress. Under certain conditions such as fibromyalgia, liver disease, and chronic fatigue syndrome (CFS), more rT3 is produced which inhibits the desirable conversion of thyroxine (T4) to T3. This internal standard and Certified Spiking Solution® is suitable for quantitation of reverse T3 serum concentrations by LC-MS/MS to monitor impact of these and other diseases on thyroid hormone levels.

Online Solid Phase Extraction and LC-MS Analysis of Thyroid Hormones in Human Serum

Thyroid hormones play critical roles in the regulation of biological processes, such as growth, metabolism, protein synthesis, and brain development. For a clinical laboratory, fast and reliable measurements of total hormone levels are important for the diagnosis and monitoring of thyroid diseases.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
