Elimination Diet and Challenge Testing

EDACT
Description
"Elimination Diet and Challenge Test" helps identify food sensitivities by temporarily removing common trigger foods like gluten, dairy, or soy. During the elimination phase, you follow a simplified diet to reduce symptoms. Foods are then reintroduced one at a time to spot reactions. Doctors recommend this approach for unexplained digestive issues, skin flare-ups, or fatigue. Results help pinpoint dietary triggers. Guided by a healthcare provider, this test supports symptom relief and helps create a long-term nutrition plan.

Test Group Description
Nutritional Assessment Group: Tests within this group analyze various aspects of an individual's nutritional status and dietary intake. These assessments provide insights into macronutrient and micronutrient levels, nutritional deficiencies, and dietary patterns.
Optimal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Normal Range
For All Individuals:
Result: Negative: No abnormalities detected.
Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Celiac disease (Autoimmune disorder triggered by gluten consumption, leading to intestinal damage)
Crohn's disease (Chronic inflammatory disorder of the digestive tract)
Eczema (Chronic skin condition characterized by dry, itchy skin and rashes)
Eosinophilic esophagitis (Inflammation of the esophagus caused by allergic reactions to certain foods)

Key Reasons For Testing
Dietary Approach: Temporarily removes specific foods to identify potential allergens or intolerances.
Food Trigger Identification: Pinpoints foods causing allergies, sensitivities, or intolerances.
Management of Food-Related Conditions: Helps manage issues like celiac disease, IBS, and food allergies.
Symptom Improvement Assessment: Tracks symptom changes during the elimination phase.
Challenge Testing: Gradually reintroduces foods to confirm triggers and assess tolerance.
Personalized Nutrition Planning: Creates tailored dietary plans for better health and symptom control.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
