TTG IgA Test

TTG IgA Test

TTG IgA test is done to detect the Transglutaminase IgA antibodies in the blood. It is done on the patient who is suffering from the clinical symptoms of celiac disease. If you are someone with the compatible clinical symptoms, patients with atypical symptoms, and individuals at increased risk (family history, previous diagnosis with the associated disorder, positivity for HLA DQ2 and/or DQ8), then this test is for you.

There is no special preparation required before the test. All you need to do is consult with your doctor. Based on the different instructions given by them, you should plan your medical health (medications and other drug-related schedules) before the test. Moreover, there is no fasting or dietary change required before the test. Eat and drink healthy. It is a blood test, so it is important for you to wear loose clothing on the test day. It will help the doctor to take your blood easily and quickly.

Different reference values help in understanding the test result and these values are same for every age and sex group. The test result with value <4.0U/mL is considered to be negative. The test result with value lying between 4.0 to 10U/mL is considered to be weak positive. The test result with the value > 10U.mL is considered to be positive. Once the test result is positive, it is important for the patient to undergo treatment. Before that, a biopsy is done for the complete diagnosis of the celiac disease.

An IgA test is performed on the blood sample to measure the level of Tissue Transglutaminase Antibodies - IgA in the blood. It is done by using the ELISA method. Your Skin and the needle are cleaned using alcohol. An elastic band is wrapped above the elbow so that the veins can grow and can be easily seen. The needle is injected into the skin, and the blood sample is collected in the tube attached to the needle. The needle is ejected from the skin, and the blood sample with your name is sent to the laboratory for analysis.
