This enables the body to show up an autoimmune response to gluten, which can be picked up by the blood tests.įor young children, another method is to perform a genetic test. Ideally, children should have been consuming barley or wheat-containing food products for at least a year. If children below 3 undergo antibody tests, the results may not be accurate. It is necessary that a pediatric gastroenterologist examines your child who could be portraying symptoms of the celiac disease like persistent diarrhea. Usually, children who carry a risk of celiac disease undergo screening at age 3. IS EMA test performed on children and babies? The next step if you have the celiac disease could be a biopsy of your intestine to ascertain the extent of the disease. The titer of IgA-EMA is indicative of the extent of gluten-sensitive enteropathy. Your response to a gluten-free diet and relief in symptoms could also mean that you are a victim of celiac disease. Your symptoms are analyzed along with the blood test result to make a diagnosis. In case the blood tests show a high level of IgA EMA and tTG antibodies, it could be an indicator of celiac disease. Even those who have mild gluten-sensitive enteropathy could have a negative EMA test.Ĭirculating IgA endomysial antibodies are found in close to 70% to 80% of patients with dermatitis herpetiformis or celiac disease. A result portraying the absence of endomysial antibodies does not, however, confirm the absence of dermatitis herpetiformis or celiac disease. If the results of the EMA blood test are negative, it clearly means there were no EMA antibodies present in the blood. However, the EMA test scores are much lower in sensitivity than the tTG-IgA test. ![]() This test implies that anyone with a high titer of EMA is sure to be a victim of celiac disease. It is used as an accompanying test along with the routine tTG-IgA test to confirm the diagnosis of celiac disease. This test is expensive and involves a high degree of technical precision. The EMA-IgA test is an important marker for celiac disease, portraying a 99% accuracy rate. Total immunoglobulin A (IgA) and Anti-tissue Transglutaminase Antibody (tTG) are the two most important tests performed in the beginning to diagnose celiac disease. Victims of celiac disease are deficient in IgA as compared to the general population. ![]() Immunoglobulin A or IgA is a common antibody that plays a pivotal role in the immune function of mucous membranes. This leads to malabsorption of nutrients from the food and associated health conditions. In severe cases, especially where it has escaped timely detection, the lining of the small intestine is completely damaged. These antibodies cause harm, by triggering inflammation of the intestine. ![]() The body begins to create antibodies called as endomysial antibodies. The protein gluten, present in food products that contain rye, barley, and wheat does not get an appropriate response from the immune system, in those suffering celiac disease. ![]() The presence of these antibodies may be indicative of an autoimmune disease known as celiac disease or dermatitis herpetiformis (a gluten-sensitive condition which shows up on the skin). EMA test is an investigative blood examination to locate the presence of certain antibodies, called Endomysial antibodies or EMA-IgA in the blood.
