Compare Celiac Disease Screening Test Ew Panel
This blood test panel screens for celiac-related antibodies and total IgA, helping you interpret patterns and decide what to do next with your clinician.
This panel bundles multiple biomarker tests in one order—your report explains how results fit together.

This is a multi-marker blood test panel that looks for immune signals linked to celiac disease. Instead of relying on one antibody, it compares several celiac-related antibodies side by side and includes total IgA so you can interpret the pattern more safely (because IgA deficiency can hide a positive result).
If you are dealing with ongoing GI symptoms, unexplained anemia, poor growth in a child, or autoimmune conditions that travel together, a celiac screening panel can be a practical first step before you change your diet.
Do I need this panel?
You may consider this celiac screening lab panel if you have symptoms that could fit celiac disease, such as chronic diarrhea or constipation, bloating, abdominal pain, nausea, unexplained weight loss, fatigue, mouth ulcers, or an itchy blistering rash (dermatitis herpetiformis). It is also commonly used when your labs show iron deficiency anemia, low folate, low vitamin D, elevated liver enzymes, or other signs that suggest malabsorption.
This panel can also be useful if you have a higher-risk medical history, even if your symptoms are subtle. Higher-risk groups include people with type 1 diabetes, autoimmune thyroid disease, a first-degree relative with celiac disease, Down syndrome, and selective IgA deficiency.
If you already started a gluten-free diet, your antibodies may fall and the panel can look “normal” even if celiac disease is present. In that situation, talk with your clinician before testing; you may need a supervised gluten challenge for results to be meaningful.
This panel supports clinician-directed care and diagnosis. It cannot confirm celiac disease on its own, and it should be interpreted alongside your symptoms, diet (gluten exposure), and—when indicated—endoscopy with small-bowel biopsy.
Celiac serology is typically measured by immunoassay; reference ranges and reporting (positive/negative vs numeric) vary by lab, so pattern interpretation matters more than any single cutoff.

Get this panel with Vitals Vault
Vitals Vault makes it straightforward to order a celiac screening blood test panel and review the results in context. Because this is a panel, you get multiple related markers from one blood draw—helpful when you want a clearer answer than a single antibody test can provide.
After your results post, you can use PocketMD to walk through what the overall pattern suggests (for example, whether the results look like classic celiac serology, whether IgA deficiency could be masking results, or whether follow-up testing is worth discussing). You can also use your results to plan next steps with your clinician, such as confirmatory testing, nutrition evaluation, or a careful plan for repeat testing.
If you are comparing options, ordering a bundled panel can reduce the chance that you miss an important companion marker (especially total IgA) and can make follow-up conversations more efficient because the key pieces are already on the table.
- One order, multiple celiac-related antibody markers plus total IgA
- Designed for pattern-based interpretation rather than a single datapoint
- PocketMD support to translate results into practical next steps
- Useful for baseline testing and for monitoring trends when clinically appropriate
Key benefits of Compare Celiac Disease Screening Test Ew
- Screens for celiac disease using multiple antibody markers instead of relying on a single test.
- Includes total IgA to help you avoid false reassurance when IgA deficiency is present.
- Helps distinguish “strongly suggestive” patterns from borderline or nonspecific results that need follow-up.
- Supports earlier evaluation of malabsorption-related issues like iron deficiency anemia or low vitamin levels.
- Provides a clearer starting point for clinician discussions about endoscopy/biopsy or additional testing.
- Can be used to track antibody trends over time when monitoring is clinically indicated (for example, after diagnosis and treatment).
- Reduces confusion by presenting the key celiac screening markers together so you can interpret them as a set.
What is the Compare Celiac Disease Screening Test Ew panel?
This lab panel is a group of blood tests that look for antibodies your immune system may produce when gluten triggers an autoimmune reaction in the small intestine. In celiac disease, exposure to gluten (proteins found in wheat, barley, and rye) can lead to inflammation and damage to the intestinal lining. That damage can interfere with nutrient absorption and cause symptoms that range from obvious GI complaints to fatigue, anemia, bone loss, fertility issues, or neurologic symptoms.
Most celiac screening strategies start with tissue transglutaminase IgA (tTG-IgA) because it is sensitive and specific in many people. But no single marker is perfect. Some people have selective IgA deficiency (more common in celiac disease than in the general population), which can make IgA-based tests look falsely negative. Others may have early disease, partial gluten avoidance, or results that fall into a gray zone.
A “compare” style panel is meant to reduce those blind spots by combining several antibody tests that complement each other. It typically includes:
• tTG antibodies (often IgA and sometimes IgG) • Deamidated gliadin peptide (DGP) antibodies (IgA and/or IgG) • Endomysial antibody (EMA) IgA, which is highly specific when positive • Total serum IgA to interpret IgA-based tests correctly
Your results are most meaningful when you are eating gluten regularly in the weeks leading up to the blood draw. If you have already eliminated gluten, antibody levels can drop, and a negative panel does not reliably rule out celiac disease.
What do my panel results mean?
Mostly negative (low) antibodies across the panel
When the antibody markers in this panel are negative or very low, it generally means there is no strong serologic evidence of celiac disease at the time of testing. The key caveat is gluten exposure: if you were eating little or no gluten, antibodies can normalize even when celiac disease is present. Another important caveat is immunoglobulin status—if total IgA is low, IgA-based tests (like tTG-IgA or EMA-IgA) may look negative even when disease exists, and IgG-based markers become more important. If symptoms persist despite a “low/negative” pattern, your clinician may consider repeat testing with adequate gluten intake, genetic testing (HLA-DQ2/DQ8) to help rule out celiac, or evaluation for other causes of your symptoms.
Clear, consistent pattern (results that “fit together”)
In a screening context, the most reassuring pattern is negative antibodies with a normal total IgA level while you are eating gluten regularly. That combination makes a missed positive less likely. On the other hand, a consistent positive pattern—such as clearly elevated tTG with a positive EMA and/or supportive DGP results—tends to be more clinically actionable because multiple markers point in the same direction. Your clinician will still interpret this alongside your symptoms and may recommend confirmatory testing (often endoscopy with biopsy) before you make major diet changes, because starting a gluten-free diet can complicate diagnosis and long-term monitoring.
One or more elevated (high) antibodies on the panel
Elevated celiac-related antibodies suggest your immune system is reacting in a way that can be seen in celiac disease, especially when elevations are strong and more than one marker is positive. A single mildly elevated marker can happen for several reasons—early disease, partial gluten restriction, lab variability, or less commonly other autoimmune/inflammatory conditions—so the overall pattern matters. If total IgA is normal and tTG-IgA is clearly elevated, the likelihood of celiac disease is higher than if only one marker is borderline. If total IgA is low, a “high” IgG-based marker (such as tTG-IgG or DGP-IgG) may carry more weight. High results are a reason to discuss next steps promptly, particularly if you have weight loss, anemia, growth concerns in a child, or symptoms of significant malabsorption.
Factors that influence celiac panel results
Gluten intake is the biggest driver: antibody tests are designed to detect an immune response to gluten, so avoidance can lower results and create false negatives. Total IgA level is another major factor; IgA deficiency can mask IgA-based markers and is one reason this panel includes total IgA. Age and clinical context matter too—some markers can perform differently in young children, and your clinician may choose follow-up tests accordingly. Certain autoimmune conditions can coexist with celiac disease and may increase the pre-test probability, but they can also complicate symptom interpretation. Finally, timing matters: if you are monitoring known celiac disease, antibodies typically decline after starting a strict gluten-free diet, but the rate varies, and persistent elevation can reflect ongoing gluten exposure, cross-contact, or less commonly refractory disease—topics best handled with a clinician who can interpret trends alongside symptoms and nutrition status.

Frequently Asked Questions
Do I need to be eating gluten for this panel to work?
Yes. Celiac antibody tests are most reliable when you are eating gluten consistently. If you have already reduced or eliminated gluten, antibody levels can fall and the panel may look negative even if celiac disease is present. If you are gluten-free, talk with your clinician before testing about whether a supervised gluten challenge is appropriate.
Do I need to fast before this blood test panel?
Fasting is not usually required for celiac antibody testing. If you are combining this panel with other labs (like lipids or glucose), fasting instructions may come from those tests instead.
Why does the panel include total IgA?
Many first-line celiac markers are IgA-based (like tTG-IgA and EMA-IgA). If your total IgA is low (selective IgA deficiency), those IgA tests can be falsely negative. Total IgA helps you and your clinician decide whether IgG-based markers should be emphasized or whether additional testing is needed.
If one marker is positive but the others are negative, do I have celiac disease?
Not necessarily. A single positive—especially if it is borderline—can occur in early disease, with partial gluten avoidance, or due to nonspecific reactivity. The overall pattern (how strongly positive, whether multiple markers agree, and whether total IgA is normal) plus your symptoms determines how concerning it is. Your clinician may recommend repeat serology with adequate gluten intake, additional tests, or confirmatory endoscopy/biopsy.
Can this panel diagnose celiac disease without a biopsy?
In many adults, diagnosis still commonly involves endoscopy with small-bowel biopsy, especially if results are not clearly positive or if the clinical picture is complex. In some pediatric pathways, very high antibody levels plus confirmatory testing may allow diagnosis without biopsy under specific guidelines. Your clinician will decide what applies to you.
Should I start a gluten-free diet before I get tested?
If celiac disease is a possibility, it is usually better not to start a gluten-free diet until testing is complete and you have a plan with your clinician. Going gluten-free can make blood tests and biopsies harder to interpret and can delay a clear diagnosis.
Is this panel the same as food allergy testing (IgE)?
No. This panel looks for autoimmune-type antibodies associated with celiac disease, not IgE antibodies that are used to evaluate immediate-type food allergy and anaphylaxis risk. If your concern is hives, wheezing, or rapid reactions after eating, ask your clinician about IgE-based allergy testing and an emergency plan.
