Test Comments: (Allele frequency varies by ethnic population)
Methodology: Multiple
Clinical Significance: Analyzes a patient's genetic profile for genes specifically associated with celiac disease.  Advanced high-resolution DNA probe analysis of HLA-DQ haplotypes allow for disease risk stratification depending upon which HLA genes are detected.  Also, testing can predict with a 95% to 100% negative predictive value (NPV) that the patient will not develop celiac disease if HLA-DQ2 and HLA-DQ8 haplotypes are not present.
