## Indications for use
EliA anti-TG Immunoassay is intended for the in vitro quantitative measurement of IgG antibodies directed to thyroglobulin (TG) in human serum and plasma (Li-heparin, EDTA) as an aid in the clinical diagnosis of autoimmune thyroiditis and Graves' disease in conjunction with other laboratory and clinical findings. EliA anti-TG uses the EliA IgG method on the instrument Phadia 250. EliA anti-TG Immunoassay is intended for the in vitro quantitative measurement of IgG antibodies directed to thyroglobulin (TG) in human serum and plasma (Li-heparin, EDTA) as an aid in the clinical diagnosis of autoimmune thyroiditis and Graves' disease in conjunction with other laboratory and clinical findings. EliA anti-TG uses the EliA IgG method on the instrument Phadia 2500/5000. EliA anti-TPO Immunoassay is intended for the in vitro quantitative measurement of IgG antibodies directed to thyroid peroxidase (TPO) in human serum and plasma (Li-heparin, EDTA) as an aid in the clinical diagnosis of autoimmune thyroiditis and Graves' disease in conjunction with other laboratory and clinical findings. EliA anti-TPO uses the EliA IgG method on the instrument Phadia 250. EliA anti-TPO Immunoassay is intended for the in vitro quantitative measurement of IgG antibodies directed to thyroid peroxidase (TPO) in human serum and plasma (Li-heparin, EDTA) as an aid in the clinical diagnosis of autoimmune thyroiditis and Graves' disease in conjunction with other laboratory and clinical findings. EliA anti-TPO uses the EliA IgG method on the instrument Phadia 2500/5000. EliA Thyroid Positive Control 250 is intended for laboratory use in monitoring the performance of in vitro measurement of antibodies against thyroid peroxidase (TPO) and thyroglobulin (TG) with Phadia 250 using the EliA IgG method.
