![]() Preparing for this Test Medications May Impact ResultsĬertain medications may impact test results. Genova offers an interpretive algorithm to aid in assessing likelihood of disease: 5 Genova does not offer the HLA-DQ2/DQ8 genetic markers. According to this guideline, children can be diagnosed with CD without a duodenal biopsy when presenting with suspicious symptoms, a strongly elevated tTG-IgA (>10 confirmed cut-off value), confirmed by a positive EMA-IgA on a separate occasion, and positive genetic testing (HLA-DQ2 and /or HLA-DQ8). The European Society for Pediatric Gastroenterology Hepatology and Nutrition (ESPGHAN) introduced a revised guideline for CD in children based on the optimization of antibody assays. International guidelines suggest that measuring immunologic analytes and genetic markers are favored to increase detection of CD. Intestinal biopsy is considered the gold standard for the diagnosis of Celiac disease. What advantage does the Celiac Profile offer compared to other diagnostics? Celiac Profile - Total IgA, tTG IgA & IgG, DGP IgA & IgG, EMA IgA.IgE Inhalants - 14 inhalants specific to 18 North American geographic regions plus total IgE.IgE Food Antibodies - 19 foods plus total IgE.IgG Vegetarian - 21 foods plus total IgE.Profiles that can be ordered together include: Often times, clinicians will order several smaller profiles together in order to see a more complete picture of the patient's immune mediated response. The Celiac Profile can be ordered as a stand-alone profile or ordered together with other profiles. 1 The exception is follow-up testing for monitoring treatment efficacy. Testing should be performed while the patient is still on a gluten-containing diet. Malabsorption with nutrient deficiencies (iron, B12, calcium).2Ĭonditions and symptoms associated with Celiac disease 1, 3, 4 This mucosal injury will eventually reduce the intestinal absorptive area and interfere with uptake of micronutrients. In susceptible individuals, gluten ingestion generates an inflammatory reaction predominantly centered in the upper parts of the small intestine. What is Celiac Disease and when should testing be considered?Ĭeliac disease is defined as an autoimmune enteropathy of the small intestine, caused by exposure to dietary gluten in genetically pre-disposed individuals. The markers include Total IgA, Anti-Tissue Transglutaminase IgA (tTG IgA) and IgG (tTG IgG), Anti-Deamidated Gliadin IgA (DGP IgA) and IgG (DGP IgG), and reflex Anti-Endomysial IgA (EMA IgA). The Celiac Profile is a blood test that uses widely accepted immunologic biomarkers to aid in the diagnosis of Celiac disease (CD). ![]()
