h-TTG /Dgp (Tissue Transglutaminase Dgp) Screen

This test is performed to help diagnose celiac disease, especially in individuals who have symptoms such as abdominal pain, bloating, diarrhea, or malabsorption. It can also be used to monitor individuals with celiac disease and evaluate their response to a gluten-free diet.

This test is performed using a sample of blood. The blood sample is sent to a laboratory, where it is analyzed for the presence of tTG and Dgp antibodies.

No, fasting is not typically required before this test.

No specific preparation is needed for this test. However, it is important to inform your doctor of any medications or supplements you are taking as these may affect the test results.

The frequency of testing will depend on your symptoms and the recommendations of your healthcare provider.

High levels of tTG and Dgp antibodies in the blood can be an indication of celiac disease. However, further diagnostic tests may be needed to confirm the diagnosis.

There are minimal risks associated with this test as it simply involves a routine blood draw.

No, this test requires a blood sample to be taken by a healthcare professional and needs to be analyzed in a laboratory.

Certain factors such as recent gluten consumption, use of certain medications, and other autoimmune conditions can affect the test results.

If your test results are positive, it means that you may have celiac disease. Your doctor will likely recommend additional tests to confirm the diagnosis and discuss potential treatment options with you.

The main treatment for celiac disease is a strict, lifelong gluten-free diet.

Yes, other conditions such as type 1 diabetes, thyroid disease, and liver disease can also cause elevated tTG or Dgp levels.

tTG antibodies are produced by the immune system in response to tissue transglutaminase, an enzyme found in the gut. Dgp antibodies are produced in response to deamidated gliadin peptides, a component of gluten. Both types of antibodies are commonly elevated in people with celiac disease.

Both tests measure the levels of specific antibodies in the blood that are commonly elevated in people with celiac disease, but they are not the same test. The tTG test measures anti-tissue transglutaminase antibodies, while the Dgp test measures Deamidated Gliadin Peptide antibodies.

The h-TTG/Dgp Screen is considered very reliable for diagnosing celiac disease, especially when combined with other diagnostic methods such as a small intestine biopsy.

Yes, it is possible to have celiac disease even if your test results are negative. If you have symptoms of celiac disease and your test results are negative, your doctor may recommend further testing.

Yes, it is actually recommended to continue eating a normal diet that includes gluten before this test. If you stop eating gluten before the test, it can affect the test results.

No, this test cannot diagnose non-celiac gluten sensitivity. It is specifically designed to detect antibodies associated with celiac disease.

While there is currently no cure for celiac disease, the condition can be effectively managed with a strict, lifelong gluten-free diet.
