Notes

  • Based on feedback from local specialists, Pathlab has changed its testing protocols for coeliac disease. From 12th May 2021, Pathlab will perform a total IgA and IgA anti-tissue transglutaminase (TTG) as the initial screening tests for coeliac disease for both adults and children. IgG anti-deamidated gliadin peptide (DGP) will only be performed automatically if the total IgA is less than 0.5g/L

    IgG DGP or IgA endomysial antibodies (EMA) will otherwise only be performed if a request is made from a specialist or by primary care on behalf of a specialist. Requests can be made through immunology@pathlab.co.nz within one week of testing the sample.
