INTENDED USE

Diagnostic Kit for Total Thyroxine (fluorescence immunochromatographic assay) is a fluorescence immunochromatographic assay for the quantitative detection of Total Thyroxine (TT4) in human serum or plasma, which is mainly used to evaluate thyroid function.It is an auxiliary diagnosis reagent.All positive sample must be confirmed by other methodologies. This test is intended for healthcare professional use only.

SUMMARY

Thyroxine(T4) is secreted by the thyroid gland and its molecular weight is 777D. The total T4(Total T4,TT4) in the serum is 50 times that of the serum T3. Among them, 99.9 % of TT4 binds to serum Thyroxine Binding Proteins(TBP),and free T4(Free T4,FT4) is less than 0.05 %. T4 and T3 participate in regulating the body’s metabolic function. TT4 measurements are used to evaluate thyroid functional status and diagnosis of diseases. Clinically, TT4 is a reliable indicator for the diagnosis and efficacy observation of hyperthyroidism and hypothyroidism.
