Coeliac DQ2/DQ8 analysis

Coeliac disease testing (HLA DQ2/DQ8 genotyping) is performed by real time PCR using an Andiatech DQ2/DQ8 kit. Approximately 99% of patients with coeliac disease have either the HLA-DQ2 molecule, the HLA-DQ8 molecule or a combination of both. Possessing these genotypes does not necessarily mean that the individualwill develop coeliac disease as other environmental and genetic factors need to be present to activate the disease. Therefore this test has a high negative predictive value and a low positive predictive value.
