It’s important to understand blood test results for celiac disease. This condition harms the small intestine and makes it hard to absorb nutrients.
We look for celiac disease antibodies to see how the body reacts to gluten. The tissue transglutaminase IgA (tTG-IgA) blood test is key. It finds celiac disease in most people with great accuracy.
At Liv Hospital, we aim for top medical care. Knowing how to read celiac test results is vital for doctors and patients.

Understanding Celiac Disease and Diagnostic Testing
Celiac disease is an autoimmune disorder caused by gluten. It affects the small intestine and is triggered by gluten in wheat, barley, and rye.
What is Celiac Disease?
Celiac disease causes inflammation and damage in the small intestine. This happens when gluten is eaten. It can lead to not being able to absorb important nutrients, causing health problems if not treated.
Symptoms of celiac disease vary from person to person. They can include stomach pain, diarrhea, feeling very tired, and losing weight.
The Importance of Accurate Diagnosis
Getting a correct diagnosis of celiac disease is key. It helps prevent serious health issues. It also starts the process of following a gluten-free diet, which is the main treatment.
The tissue transglutaminase IgA antibody (tTG-IgA) test is often used. It has a high sensitivity and specificity, making it a reliable test.
Several blood tests help diagnose celiac disease. Here’s a look at some:
| Test | Sensitivity | Specificity |
| tTG-IgA | 78-100% | 90-100% |
| EMA-IgA | 85-98% | 97-100% |
| DGP | 88-95% | 90-95% |
It’s important for both healthcare providers and patients to understand celiac disease and its tests. Accurate diagnosis helps people live a better life by following a gluten-free diet.
Common Blood Test for Celiac Sprue Types and Markers
To find out if someone has celiac disease, doctors use special blood tests. These tests look for certain markers in the blood. They help find antibodies linked to the disease.
Tissue Transglutaminase IgA Antibody (tTG-IgA)
The tTG-IgA test is a top choice for spotting celiac disease. It checks for antibodies against tissue transglutaminase, an enzyme in the gut. High levels of these antibodies suggest celiac disease.
The National Institute of Diabetes and Digestive and Kidney says this test is very reliable. It has high sensitivity and specificity.
Endomysial Antibodies (EMA-IgA)
Endomysial antibodies are also tested for celiac disease. The EMA-IgA test is very specific. A positive result means you likely have the disease.
But, it’s not as sensitive as the tTG-IgA test. This means it might miss some cases of celiac disease.
Deamidated Gliadin Peptides (DGP)
The DGP test looks for antibodies against deamidated gliadin peptides. It’s useful for kids under two or those with IgA deficiency. DGP antibodies are linked to celiac disease, helping confirm a diagnosis.
Knowing about these blood tests and markers is key. It helps doctors understand test results and make accurate diagnoses. By combining test results, doctors can give a clear diagnosis and suggest the right treatment.
How to Interpret Your Celiac Test Results
Understanding your celiac blood test results can be tricky. But knowing what they mean is key to getting a diagnosis. When you get your results, there are a few things to look at to see if you have celiac disease.
Understanding Positive Test Results
A positive test means you have certain antibodies linked to celiac disease. These include Tissue Transglutaminase IgA Antibody (tTG-IgA), Endomysial Antibodies (EMA-IgA), and Deamidated Gliadin Peptides (DGP). If tTG-IgA is positive, it’s a strong sign of celiac disease. But, a biopsy of your small intestine is usually needed to confirm it.
It’s essential to consult with a healthcare professional to fully understand your results. They can guide you on what to do next and help make sense of your health.
Making Sense of Negative Results
Negative results can be reassuring. But, it’s important to remember that they don’t rule out celiac disease, mainly in people with IgA deficiency. Sometimes, more tests are needed to confirm the diagnosis.
The Impact of IgA Deficiency on Testing
IgA deficiency can make celiac tests less accurate. This is because some tests look for IgA antibodies. People with IgA deficiency might need tests for IgG antibodies to get a correct diagnosis.
Next Steps After Receiving Results
Whether your results are positive or negative, talking to your healthcare provider is key. They can suggest what to do next. This might include more tests, changes in your diet, or further checks.
| Test Result | Implication | Next Steps |
| Positive tTG-IgA | Strong likelihood of celiac disease | Consult healthcare provider, consider intestinal biopsy |
| Negative | Celiac disease less likely, but not ruled out in IgA deficiency | Discuss with healthcare provider, consider alternative tests if IgA deficiency is suspected |
| Positive EMA-IgA or DGP | May indicate celiac disease | Further evaluation and consultation with healthcare provider |
Understanding your celiac test results is a big step in managing your health. By working with your healthcare provider and following their advice, you can get a correct diagnosis and the right treatment.
Conclusion
Living with celiac disease means sticking to a gluten-free diet for life. This can greatly lessen symptoms and stop serious problems. Knowing about celiac disease antibodies and how to read test results is a big step towards better health.
Getting a correct diagnosis through blood tests is key to finding out if you have celiac sprue. We talked about how to understand celiac panel results. This includes the role of tissue transglutaminase IgA antibody (tTG-IgA) and endomysial antibodies (EMA-IgA).
Following a strict gluten-free diet can help most people with celiac disease feel better or even symptom-free. We aim to have given you useful tips on reading celiac blood test results. This should help you manage your condition well.
FAQ
What is a celiac blood test, and how does it work?
A celiac blood test looks for antibodies in your blood linked to celiac disease. It checks for levels of antibodies like tTG-IgA, EMA-IgA, and DGP. These antibodies are made when your body reacts to gluten.
What does a positive celiac blood test result mean?
A positive result might suggest you have celiac disease. But, it’s not a sure sign. You might need more tests, like a biopsy, to confirm it.
Can I stil have celiac disease if my blood test results are negative?
Yes, you could have celiac disease even with negative test results. This is more likely if you have IgA deficiency. You might need more tests then.
How long does it take to get celiac blood test results?
Getting your test results can take a few days to a week. It depends on the lab and the tests you had.
What is the tTG-IgA test, and why is it used?
The tTG-IgA test checks for tissue transglutaminase IgA antibodies in your blood. It’s very accurate for finding celiac disease.
What is IgA deficiency, and how does it affect celiac disease testing?
IgA deficiency means your body doesn’t make enough IgA antibodies. This can mess up celiac disease tests, like the tTG-IgA test. Tests like DGP might be used instead.
How do I interpret my celiac panel results?
Understanding your celiac panel results needs a good grasp of the markers and what they mean. It’s best to talk to a healthcare professional about your results.
What is the significance of EMA-IgA and DGP in celiac disease diagnosis?
EMA-IgA and DGP are markers for celiac disease. EMA-IgA is very specific. DGP is helpful, like in kids or those with IgA deficiency.
Can genetic testing help diagnose gluten sensitivity or celiac disease?
Genetic testing can show if you’re at risk for celiac disease. But, it can’t directly diagnose it. It’s used with other tests to help figure out if you have it.
What are the next steps after receiving celiac blood test results?
After getting your test results, talk to a healthcare professional. They’ll help you understand what it means and what to do next. This might include more tests, starting a gluten-free diet, or other steps.
