CLEIA - ChemiLuminescent Enzyme Immunoassay
Test principle: Two-Step sandwich assay
Clinical backgroundTSH - Thyroid Stimulating Hormone stimulates the thyroid gland to secrete the hormone thyroxine (T4).
T4 is converted to triiodothyronine (T3), which is the active hormone that stimulates metabolism.
About 80% of this conversion is in the liver and other organs, and 20% in the thyroid itself.
Blood TSH levels closely reflect changes in thyroid function.
The TSH assay can play an important role as a primary marker in the diagnosis of thyroid disease.
Simultaneous assays of TSH and other thyroid hormones may help reveal anomalies in the feedback mechanism, making it possible to distinguish thyroid diseases from pituitary and hypothalamus abnormalities or resistance to thyroid hormone.
