No Reticulan Antibodies will be resulted due to Reagent Backordered.
The Celiac Disease Evaluation Panel (EPIC Test Code IMO123) includes measurement of Reticulin IgA and IgG antibody through Quest Diagnostics. Quest Diagnostics experienced a disruption to their reagent supply for Reticulin IgA and IgG testing beginning in May 2022. Samples were held at a Quest laboratory with the anticipation that reagent would be available in mid-June 2022. The anticipated reagent supply was not received and currently has no estimated delivery date. An alternate lab for Reticulin IgA and IgG testing has not been identified at this time. Because future availability is unknown, current pending orders for Reticulin IgA and IgG are being cancelled. Quest Diagnostics recommends substituting tissue Transglutaminase IgA and IgG which are already included in the Celiac Disease Evaluation Panel. Future orders for the Celiac Disease Evaluation Panel will not include Reticulin IgA and IgG antibody until this reagent backorder has been resolved.
