Consult your doctor or a gastroenterologist. They can order the appropriate blood tests and, if necessary, an intestinal biopsy to confirm the diagnosis. It's important to continue consuming gluten until testing is complete to ensure accurate results.

Understanding the Diagnostic Process for Celiac Disease
Diagnosing celiac disease typically involves a combination of blood tests and intestinal biopsies. These tests help to determine if an individual has an immune reaction to gluten and if there is damage to the small intestine.
Blood Tests for Celiac Disease
Initial screening often involves blood tests that measure certain antibodies. Common blood tests include:
- Tissue Transglutaminase IgA (tTG-IgA): This is the most common and reliable blood test for celiac disease.
- Endomysial Antibody IgA (EMA-IgA): Highly specific for celiac disease, but less sensitive than tTG-IgA.
- Deamidated Gliadin Peptide (DGP IgA and IgG): Useful for individuals with IgA deficiency, as IgA antibodies may be falsely negative.
- Total Serum IgA: To rule out IgA deficiency, which can affect the accuracy of IgA-based antibody tests.
It's crucial to continue consuming gluten while undergoing these blood tests to ensure accurate results. A gluten-free diet prior to testing can lead to false negatives.
Intestinal Biopsy
If blood tests suggest celiac disease, an intestinal biopsy is usually performed to confirm the diagnosis. This involves taking small tissue samples from the small intestine during an endoscopy. The samples are then examined under a microscope to look for damage to the villi, the small finger-like projections that line the intestine and help absorb nutrients.
Marsh criteria are often used to classify the degree of damage seen in the biopsy samples, ranging from Marsh 0 (normal) to Marsh 3 (severe villous atrophy).
Genetic Testing
Genetic testing for HLA-DQ2 and HLA-DQ8 genes can also be useful, as these genes are present in almost all individuals with celiac disease. However, having these genes does not guarantee the development of celiac disease; they simply indicate a genetic predisposition.
Differential Diagnosis
It is important to rule out other conditions that may cause similar symptoms, such as irritable bowel syndrome (IBS), Crohn's disease, and lactose intolerance.
Treatment Options
The primary treatment for celiac disease is a strict gluten-free diet. This means avoiding all foods and products containing wheat, barley, and rye. With proper dietary management, most individuals with celiac disease experience symptom relief and healing of the intestinal lining.
Preventive Measures
There is no known way to prevent celiac disease. Early diagnosis and adherence to a gluten-free diet are the best strategies for managing the condition and preventing long-term complications.

Frequently Asked Health Questions
Are pre-existing conditions covered?
Yes. Under modern healthcare laws (such as the ACA in the US or universal systems), insurers cannot deny coverage or charge you more due to a pre-existing medical condition.
What is an Out-of-Pocket Maximum?
It is the absolute most you will have to pay for covered medical services in a year. Once you hit this limit, your insurance pays 100% of all covered costs.
