Diagnostic Value of Persistently Low Positive TGA-IgA Titers in Symptomatic chIldren with Suspected Celiac Disease
Objectives:
While the algorithm to diagnose celiac disease (CD) in children with elevated anti-transglutaminase IgA (TGA-IgA) titers (> 10 times upper limit of normal, ULN) is well defined, the management of children with low TGA-IgA values represents a clinical challenge. We aimed to identify the diagnostic value of persistently low positive TGA-IgA titers in predicting CD in children.
