Used in research settings to accurately measure levels of human thyroid-binding globulin (TBG) in serum or plasma samples. This ELISA kit enables the quantification of TBG, which plays a key role in transporting thyroid hormones in the bloodstream. It is widely applied in studies related to thyroid function, hormonal imbalances, and disorders such as hypothyroidism or hyperthyroidism. The assay supports clinical research and laboratory investigations by providing a reliable, sensitive, and specific method for monitoring TBG concentrations, helping to assess thyroid status and liver function, as TBG levels can be influenced by hormonal, genetic, and pathological conditions.
