The VeriLumenTM<\/sup>\u00a0FT4 Rapid Test is a fluorescence immunochromatographic\u00a0assay for the quantitative measurement of free thyroxine (FT4) in human whole blood, plasma, or serum samples. FT4 is the biologically active fraction of thyroxine and plays a key role in regulating metabolism, growth, and energy balance. Its concentration is widely used in the clinical assessment of thyroid function, reflecting circulating thyroid hormone availability. The assay provides rapid quantitative results to support timely clinical evaluation in laboratory and point-of-care settings.<\/p>

This test is mainly used in the clinical evaluation of thyroid function, supporting assessment of patients with suspected hypo- or hyperthyroidism. Quantitative FT4 measurement supports clinical decision-making when interpreted together with clinical findings and other thyroid function tests, helping to evaluate hormonal imbalance and treatment response.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
