Bloated after every meal, anemic no matter how much iron you take, and still no diagnosis?
If your gut symptoms, fatigue, or unexplained iron deficiency have no clear cause, gluten could be the trigger your immune system is quietly reacting to. The Tissue Transglutaminase IgA & IgG Test in Dubai is the first-line blood panel used to screen for celiac disease. At Enfield Blood Test Dubai, you can book it through a DHA-licensed laboratory with home collection and results in 24–48 hours.
This blood test looks for antibodies linked to celiac disease, specifically ones your immune system makes when it reacts to gluten. In someone with celiac disease, eating gluten triggers an immune response that mistakenly targets tissue transglutaminase, an enzyme found in the lining of the small intestine. Left unaddressed, this reaction gradually damages the gut, leading to inflammation and problems absorbing nutrients.
Doctors typically start with the tTG-IgA test, since it’s the most sensitive and specific option available for initial screening. However, if a patient has low overall IgA levels, this test can produce a false negative. In that case, the tTG-IgG test is used instead of or alongside it. Together, these two tests offer one of the more reliable ways to screen for celiac disease and help distinguish it from non-celiac gluten sensitivity. Depending on the results, a doctor may recommend further evaluation through an endomysial antibody (EMA) test, a deamidated gliadin peptide (DGP) test, or an endoscopy.
Consider a tissue transglutaminase antibody test if you experience any of the following:
The Cost of Celiac Disease Blood Test in Dubai starts from 350 AED. The price might fluctuate and depend on which markers and panels are ordered. That’s why the exact final price will be decided after your consultation. Below is an indicative celiac disease blood test cost in Dubai 2026 breakdown:

| tTG-IgA & IgG Combined Panel | tTG-IgA + tTG-IgG + Total IgA | 500 AED to 650 AED |
| Comprehensive Celiac Panel | tTG-IgA/IgG + CBC + Iron Studies + Vitamin D | 750 AED to 950 AED |
| Home Collection Add-On | Nurse visit, any package | 50 AED to 150 AED |
The tissue transglutaminase antibody test can identify or point to several conditions and risk factors:
Key benefits of this test include:
Keep the following in mind before your appointment:
Below is what to expect during the testing process:
You can book online on our website or via WhatsApp. Choose a clinic visit or home collection. Make sure your markers confirm what your doctor has requested (tTG-IgA, tTG-IgG, or the combined celiac panel).
A staff member of our team will confirm you’re still eating gluten normally and review current medications. They also check whether any fasting tests are being combined with your tTG antibody test.
A phlebotomist draws a small venous blood sample from your arm into a standard serum tube. The tTG test sample type is always venous blood, not a finger prick. The draw takes about 5 to 10 minutes.
Your sample is transported under temperature-controlled and chain-of-custody conditions to the accredited lab in case of home collection. The overall accuracy is identical to an in-clinic draw in the blood test at home.
The lab uses immunoassay technology to detect and quantify tTG-IgA and/or tTG-IgG antibody levels, alongside total IgA where ordered.
Results are checked against standard reference ranges and released digitally. The tTG test turnaround time is typically 24 to 48 hours.
Your results are reviewed alongside symptoms by our doctor or gastroenterologist and advises on next steps such as an EMA test, DGP test, or endoscopy for celiac disease.
Once your sample is collected, here’s what typically happens next:
Your report will show measured tTG-IgA and tTG-IgG antibody levels alongside the laboratory’s reference range, plus your total IgA level if it was tested. Results are generally read as normal, borderline, or positive. Your results are also always interpreted alongside your symptoms, not in isolation.
Reference ranges for this panel are as follows:
| Marker | Typical Reference Range |
| tTG-IgA | Less than 20 U/mL (negative) |
| tTG-IgG | Less than 20 U/mL (negative) |
| Total IgA | 0.7 to 4.0 g/L (adult reference) |
The celiac disease normal range varies slightly between laboratories and assay methods. You need to always interpret your result against the range printed on your own report.
Antibody levels are higher than the reference range when the tTG antibody test is positive. Celiac disease is strongly suggested by this elevated level. Since this is one typical Tg antibody positive result, other autoimmune diseases may also occasionally result in a positive result. An upper endoscopy and small intestine biopsy are usually necessary for confirmation. The preferred method of diagnosing celiac disease is still a biopsy rather than a blood test. Prior to this confirmation step, do not begin a gluten-free diet.
The standard tTG antibody negative result indicates that celiac disease is unlikely if both markers are negative. A tiny percentage of people with actual celiac disease may still test negative, especially if they have an undiagnosed IgA deficiency or have already cut back on gluten before the test. In the event that symptoms persist following a supervised gluten challenge prior to celiac testing, your doctor may suggest a DGP test, EMA test, HLA-DQ2/DQ8 genetic testing, or repeat testing.
Below is how the two markers compare:
| Aspect | tTG–IgA | tTG–IgG |
| Role | First-line, primary celiac disease test | Secondary marker, used when IgA is deficient |
| Sensitivity | High in people with normal IgA | Lower specificity alone, useful as a backup |
| Best used for | General celiac disease screening | IgA deficiency and celiac testing cases |
| Requires Total IgA? | Yes, to rule out deficiency | Often ordered because Total IgA is already low |
| Typical cost (AED) | 350 AED | 350 AED |
Here’s how this panel compares to other celiac disease tests:
| Test | Purpose | Notes |
| tTG-IgA / IgG | First-line antibody screening | Most sensitive and widely used celiac disease test |
| Endomysial Antibody (EMA) | Confirms a positive or borderline tTG result | Highly specific, more expensive, manual technique |
| Deamidated Gliadin Peptide (DGP) | Used in IgA-deficient patients and young children | Often combined with tTG-IgG |
| HLA-DQ2/DQ8 Genetic Test | Rules out celiac disease if negative; doesn’t confirm it if positive | Useful for family screening |
| Endoscopy with Biopsy | Confirms diagnosis | Diagnostic gold standard after a positive blood test |
A negative result paired with no ongoing symptoms usually means repeat testing isn’t necessary. For those already diagnosed with celiac disease, doctors often recheck tTG IgA levels every 6 to 12 months to monitor progress on a gluten-free diet. Antibody levels are expected to decline gradually as the intestine heals with strict gluten avoidance.
Below are the reasons why patients choose us for celiac disease testing:
Don’t let unexplained bloating, fatigue, or iron deficiency go uninvestigated. Booking your Tissue Transglutaminase IgA & IgG Test in Dubai is simple with Enfield Blood Test Dubai. You can choose a clinic visit or home collection. Your sample is drawn in minutes, and you receive doctor-reviewed results straight to your email or WhatsApp.
The cost for a tTG-IgA and tTG-IgG test starts from 350 AED. A combined tTG-IgA & IgG celiac panel cost is higher. Pricing varies by lab and whether home collection is added or not.
tTG-IgA is the primary and first-line antibody test. tTG-IgG is used mainly when IgA deficiency and celiac testing overlap. Low total IgA can cause a false-negative result.
Most results are available within 24 to 48 hours through an accredited Dubai laboratory.
No. A referral is usually not mandatory to book directly. We suggest you review your results with a doctor or gastroenterologist afterward.
Yes. Celiac disease in children is often investigated with tTG-IgA and tTG-IgG testing. It is performed particularly for faltering growth or chronic diarrhea and a family history of celiac disease.
It suggests an autoimmune reaction to gluten consistent with celiac disease. Diagnosis is usually confirmed with an endoscopy and small intestine biopsy. The celiac disease biopsy vs. blood test remains the standard pathway.
Yes. All results are handled under strict celiac disease test data privacy protocols and released only to you and the doctor you choose to share them with.
No. Keep eating gluten normally. Starting a gluten-free diet early is a gluten challenge issue that can normalize antibody levels and cause a false-negative celiac disease test result.
Yes. A DHA-licensed nurse collects a venous blood sample at your home or office anywhere in Dubai, with the same accuracy as an in-clinic tTG test.
