## Indications for use
UniCAP Thyroglobulin ImmunoCAP™ is a device for the in vitro quantitative measurement of IgG antibodies specific for Thyroglobulin (TG) in human serum and plasma. UniCAP Thyroglobulin ImmunoCAP is intended to be used with the instrument UniCAP together with reagents as stated in the Directions For Use provided with UniCAP Specific IgG. It is intended for in vitro diagnostic use as an aid in the clinical diagnosis of certain thyroid diseases, such as autoimmune thyroiditis and Graves’ Disease and is to be used in clinical laboratories, as well as, physician office laboratories. UniCAP Specific IgG is an in vitro test system for the quantitative measurement of antigen specific IgG antibodies. The corresponding antigen for the specific antibody to be measured by UniCAP Specific IgG is bound to the Antigen ImmunoCAP solid phase component of the UniCAP Specific IgG System. UniCAP Specific IgG assay is to be used with the instrument UniCAP. It is intended for in vitro diagnostic use in conjunction with other clinical findings, and is to be used in clinical laboratories, as well physician office laboratories. UniCAP Thyroglobulin IgG Antibodies Controls are intended for laboratory use in monitoring the performance of in vitro quantitative measurement of IgG antibodies specific for Thyroglobulin in human serum. UniCAP Thyroglobulin IgG Antibodies Controls are intended to be used with the instrument UniCAP.
