No common urgent flag from this test alone
This test looks for special fighters in your blood. They are called tissue transglutaminase IgA, or tTG-IgA. Your body makes these fighters when it reacts to gluten.
Your doctor orders this test to help find out if you have celiac disease. This is a condition where eating gluten hurts your small intestine. It's also used to check on people who already know they have celiac disease.
Reference ranges for tTG-IgA can vary between different laboratories. The interpretation of your results also depends on factors like your age and overall health.
