Product

Autoimmune EIA Anti-Tissue Transglutaminase (tTG) IgA Test; Material Number 425-2260; Lot number 18200A - Product Usage: The assay is an aid in the diagnosis of celiac disease (gluten-sensitive enteropathy) and should be used in conjunction with other serological tests and clinical findings.

Reason

An elevated lot-to-lot bias was observed for Autoimmune EIA Anti-Tissue Transglutaminase (tTG) IgA when compared to a previous lot of product. The observed elevated bias between these two lots is largely due to samples with higher levels of antibodies. With the cut-off for the assay being 15 U/mL, the clinical classifications for most samples would remain unchanged.
