Test Overview

Test Methodology

Molecular Typing (SSOP)

Test Usage

The HLA class II antigens DQ2 (DQA1*05/DQB1*02) and DQ8 (DQA1*0301/DQB1*0302) are the major risk factors predisposing individuals to Celiac Disease and account for over 35% of the genetic risk. Close to 90% of patients with Celiac Disease express the HLA-DQ2 molecules with most of the remainder expressing the HLA-DQ8 molecule. The DQ variant DQA1*02/DQB1*02 is associated with weak/equivocal risk of Celiac Disease.

Reference Range

Interpretive report will indicate presence or absence of HLA-DQ2 and DQ8.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
