Tissue Transglutaminase Antibody and Celiac Disease- What You Need to Know


You probably don't hear about tissue transglutaminase very often. Despite that, you should know that this substance is fundamental to detecting celiac disease and other similar illnesses. Celiac disease is increasingly prevalent, and this ailment can be life-threatening.

Please keep reading to find out more about the tissue transglutaminase antibody test, auto-immune diseases, and other information related to them.

What are TTG Antibody and Gluten?

Tissue transglutaminase antibody refers to a particular substance that your body makes when it becomes sensitive to gluten. Gluten is a type of protein commonly found in most foods such as bread, cookies, etc.

In small quantities, gluten shouldn't be harmful to your body. However, some people develop sensitivities to this protein for various reasons. Gluten tends to stick to the internal lining of the stomach and small intestine. When this happens, the immune system creates antibodies to try to remove them from there. During this process, the body attacks its healthy tissues, and this is how celiac disease develops.

What is Celiac Disease?

Celiac disease is one of the later stages of gluten sensitivity. Not everyone sensitive to gluten develops celiac diseases, but the risk is still pretty high.

When you have celiac disease, the body triggers a response similar to an allergic reaction. It tries to remove gluten from the lining of your intestines, which will give you unpleasant symptoms. Let's take a look at a few symptoms of celiac disease.

  • Fatigue
  • Diarrhea and weight loss
  • Bloating and gas
  • Constipation
  • Nausea and vomiting
  • Stomach pain
  • Irritation and confusion

Celiac disease can be life-threatening if the right treatment isn't administered correctly. In most cases, people with celiac disease should avoid gluten at all costs. This will prevent any allergic reaction, and the symptoms mentioned above won't appear.

Other types of auto-immune diseases can also develop in people who have gluten sensitivity. For example, dermatitis herpetiformis another type of manifestation of celiac disease. It usually manifests as listers filled with water that appear on the skin. These blisters are usually itchy, and they are accompanied by other unpleasant symptoms.

Diagnosing celiac disease and other auto-immune diseases can be done with the help of a tissue transglutaminase antibody. If these antibodies are detected in high quantities in your system, it means that your body is actively fighting inflammation that might be caused by celiac disease.

Based on this result, your doctor might follow a strict diagnosis protocol to discover if you really have celiac disease or not. The TTG antibody test is an inexpensive and accessible way of finding out if you're dealing with a life-threatening illness.

Even if you have a negative TTG antibody result, this doesn't necessarily mean that you don't have a gluten sensitivity. You might be at a lower risk of developing celiac disease, and your doctor might order additional tests to make sure that gluten is not harmful to your body.

What Are the Normal Ranges of Tissue Transglutaminase?

TTG is present throughout the entire human body but in small quantities. For example, anything under 20 units is considered to be a negative result. This means that the person in question might have certain symptoms, but these are not caused by celiac disease. This is also true if the person being tested didn't consume gluten in the last weeks.

A test result between 20 and 30 units is labeled as "weak positive." This is not a confirmed diagnosis of celiac disease, but the patient might be affected by this condition. Further tests are necessary to see if the person in question has severe gluten sensitivity or celiac disease is indeed developing in his body.

Lastly, anything over 30 units is a positive result. This means that the patient is likely to have celiac disease. If you get this result, your doctor will order an intestinal biopsy to confirm the diagnosis of celiac disease. There is a strict protocol to be followed to diagnose celiac disease, but it all starts with a simple tTG antibody test you can order online.

Who Should Order the TTG Antibody Test for Celiac Disease?

Celiac disease is not something to take lightly. Apart from the fact that it gives you horrible symptoms, it can be a life-threatening ailment. That's why you should order the test and see if you're at risk, especially if you regularly consume products containing gluten. This protein is present in most foods and beverages available on the market, so everyone ingests a small quantity of gluten daily.

If you experience the symptoms mentioned above, you are strongly encouraged to order the test. Multiple illnesses can cause fatigue, abdominal pain, and diarrhea, but you need to make sure celiac disease is not the culprit.

Lastly, celiac disease tends to run in families. If your parents or other close relatives have celiac disease, auto-immune illnesses, or gluten sensitivity, you are at a higher risk of developing this condition. A simple tissue transglutaminase blood test will reveal how big of a risk you're facing.
