Celiac disease damages the villi, which are finger-like projections in the small intestine. Villi are responsible for absorbing nutrients from food. Because of this, it is highly likely that people with celiac disease will be deficient in essential vitamins and nutrients when diagnosed. Laboratory tests should be done within three to six months following a diagnosis and annually for the rest of your life.
Laboratory Tests for Celiac Disease Management After Diagnosis
Regular monitoring with blood tests can help to answer the following questions:
- Is the small intestine healing?
- Am I being followed and screened for common nutritional deficiencies and associated diseases?
- Am I getting better?
- Am I being exposed to gluten?
Laboratory tests to include in celiac disease management include:
- Celiac disease antibodies (IgA-tTG)
- Nutritional anemia profile (hemoglobin, hematocrit, folate, ferritin, vitamin B12)
- Vitamin profile (thiamin, vitamin B6, 25-hydroxy vitamin D)
- Mineral profile (copper, zinc)
- Lipid profile
- Electrolyte and renal profile
- Complete blood count (CBC)
- Thyroid stimulating hormone (TSH)
Adults with celiac disease should have a bone mineral density scan within the first year after diagnosis.
The specific tests you receive will vary depending on your situation and your doctor's advice. Please use these tests as a guide to your lifelong management of celiac disease.
While blood tests are extremely helpful, visiting a registered dietitian knowledgeable of celiac disease and the gluten-free diet is considered the "gold standard" for understanding how to know if you are accidentally being exposed to gluten (even if symptoms are not present).
At-Home Monitoring Test
imaware™ has developed the most comprehensive home-based celiac disease monitoring test that provides actionable insights and information that can help you take control of your health.
Beyond Celiac has partnered with imaware™ to bring awareness to their home-based celiac disease test and to increase celiac disease awareness and diagnosis rates.
Want to know if your gluten-free diet is effective?
Making major lifestyle and dietary changes after diagnosis is difficult, especially for those recently diagnosed. A majority of people do not follow-up with their doctors after invoking the gluten-free diet, and healing may not fully take place.
Studies have shown that it can take between 15-20 months of strict gluten-free diet before complete internal healing can take place. It is critical to be monitored during this phase to ensure your diet and lifestyle are providing you the needed benefits.
imaware™ helps you monitor and track the effectiveness of your gluten-free diet.
