About Anti Tissue Transglutaminase (IgM)
Anti tTG IgM completes the celiac antibody panel and can add useful information in specific cases where the IgA and IgG results are unclear or borderline.
No fasting is required, and as with the other tTG tests, maintaining your normal gluten intake before the blood draw matters for an accurate result.
How to Prepare
- No fasting required.
- Keep eating gluten as usual before testing.
