General instructions for Serum antitransglutaminase, antigliadin, and antiendomysium antibodies
Blood test to detect specific antibodies and help diagnose coeliac disease.
- Fasting: No fasting is required for this test. If the blood sample is taken together with other tests, you may need to come fasting.
- Medication: Some drugs that suppress the immune system can alter the amount of antibodies in the blood. However, any decision to stop, continue or adjust your usual medication must always be discussed with your doctor.
- Clothing and Accessories: We suggest wearing comfortable clothing, preferably short-sleeved or with loose sleeves that can easily be rolled up above the elbow to give access to the vein. There are no restrictions on jewellery, piercings or watches.
- Specific Requirements: Before the test it is essential that you are eating gluten regularly as part of your diet (bread, pasta, biscuits or other foods containing wheat, barley or rye). If you have removed or reduced gluten, tell your doctor before having the test, because without gluten the result could be falsely negative. There is no need to come with a full bladder or with a companion.
- Discomfort or pain after the test: You will feel a slight, brief prick when the needle is inserted into the vein. After the blood draw, it is completely normal for a small bruise to form or to feel very slightly dizzy for a moment.
