What is the significance of the TTG IgA serum test?
It is done either to diagnose celiac disease or to check on people with this condition.
What is celiac disease?
It is an autoimmune disorder of the digestive tract where the immune system reacts to food that contains gluten – a protein found in wheat, barley, rye, and oats. If you have celiac disease, your digestive system will react and can damage the small intestine.
Why should I get it done?
If you’re having symptoms of celiac disease, your healthcare provider will suggest you get this test done. If you have celiac disease, you may have any of the following symptoms:
- Distension of abdomen
- Abdominal pain
- Diarrhea
- Constipation
- Bad–smelling stool
- Gastric accumulation
- Nausea or vomiting
- Lactose intolerance
What is the normal range of tTg IgA?
If you’re blood tTg IgA levels are:
- < 4.0 U/ml – negative
- 4.0- 10.0 U/ml – weak positive
- >10.0 U/ml – positive
What if the tTg IgA serum test is positive?
The positive result indicates the presumptive celiac disease, and it should be followed by an intestinal biopsy to confirm the condition.
What if the tTg IgA serum test is negative?
The negative tTg IgA means all the symptoms observed are not caused by this condition and require further assessment.
Are celiac disease and wheat allergy the same?
Usually, people get confused between celiac disease and wheat allergy. Celiac disease is an autoimmune disorder caused by a specific protein (gluten) found in wheat, barley, oats, and rye whereas wheat allergy is an allergic reaction to the proteins found in wheat.
