IgA and IgG antibodies to deamidated gliadin-derived peptides (DGP) and human tissue transglutaminase (h-tTG) in human serum
2 - 5 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
0.25 mL (Note: This volume does not allow for repeat testing.)
Red-top tube or gel-barrier tube
Serum separated from clot
Microbially-contaminated, heat-treated, or specimens containing visible particulate; grossly hemolyzed or lipemic serum specimens
For detection of IgA and IgG antibodies to deamidated gliadin-derived peptides (DGP) and human tissue transglutaminase (h-tTG) in human serum. The presence of these antibodies can be used in conjunction with clinical findings and other laboratory tests to aid in the diagnosis of IgA-sufficient and IgA-deficient celiac disease.
