Description

Product Overview

The Free T3 Test Kit is a competitive fluorescence immunoassay designed for quantitative determination of circulating free T3 levels. Free T3 is the biologically active thyroid hormone that regulates metabolism, cardiovascular function and neurological development.

Intended Use

For in vitro quantitative determination of free triiodothyronine (fT3) in serum, plasma or whole blood as an aid in diagnosis of thyroid disorders.

Clinical Significance

Supports diagnosis of hyperthyroidism and hypothyroidism, thyroid function monitoring and endocrine disorder evaluation.

Test Principle

Competitive fluorescence immunoassay where free T3 in the sample competes with fluorescence-labelled T3 antigen for monoclonal antibody binding sites and signal intensity is inversely proportional to concentration.
