Celiac Disease: Check for Gluten Sensitivity - Save 20%

The Tissue Transglutaminase (tTG) IgA Antibody Test screens for celiac disease by detecting IgA antibodies against tissue transglutaminase, a marker of gluten intolerance. Elevated levels suggest an autoimmune reaction that damages the small intestine. Doctors order this test for patients with chronic diarrhea, bloating, weight loss, or anemia. Results provide critical insight for diagnosing celiac disease and guiding gluten-free diet management.

The Immunoglobulin A (IgA) Test measures IgA antibody levels in blood to evaluate immune system health and mucosal defense in the respiratory and digestive tracts. Low IgA may indicate immune deficiency, celiac disease, or recurrent infections, while high levels may suggest autoimmune disorders, liver disease, or chronic inflammation. Doctors use this test to assess unexplained illness or immune imbalance. Results provide key insight into antibody function and overall immunity.

The Gliadin Deamidated Peptide IgG IgA Antibodies Test detects both IgG and IgA antibodies against deamidated gliadin peptides, highly specific markers for celiac disease. Elevated results indicate an autoimmune reaction to gluten that can damage the small intestine. Doctors use this test to confirm suspected celiac disease, evaluate unexplained digestive issues, or monitor compliance with a gluten-free diet, often alongside tTG and other celiac antibody tests.

The Complete Blood Count with Differential and Platelets Test is a comprehensive blood test that checks red blood cells, white blood cells, hemoglobin, hematocrit, and platelets. The differential analyzes types of white blood cells to detect infections, anemia, clotting abnormalities, immune conditions, and certain cancers. This essential test is often ordered for routine health exams, diagnosis, and monitoring treatment progress.

The Comprehensive Metabolic Panel (CMP) Test measures 21 markers to assess metabolic health, liver and kidney function, and electrolyte balance. It includes glucose, calcium, sodium, potassium, chloride, CO2, albumin, globulin, A/G ratio, total protein, bilirubin, ALP, AST, ALT, BUN, creatinine, BUN/creatinine ratio, and eGFR. The CMP helps detect diabetes, liver or kidney disease, and supports routine screening and chronic condition monitoring.

The Sed Rate Test, also called the ESR Test, measures how quickly red blood cells settle in a sample of blood. A faster rate may signal inflammation caused by infections, autoimmune diseases, arthritis, or other chronic conditions. Doctors use this test to investigate unexplained fever, joint pain, or muscle aches, and to monitor inflammatory disorders such as lupus or rheumatoid arthritis. The Sed Rate Test provides important insight into overall inflammatory activity.

The C-Reactive Protein (CRP) Test measures CRP levels in blood to detect inflammation in the body. Elevated CRP may indicate infections, autoimmune disorders, or chronic diseases such as arthritis, cardiovascular disease, or inflammatory bowel disease. Doctors use this test to assess acute illness, monitor treatment response, and evaluate risk for heart disease. The CRP test provides key insight into inflammation, immune health, and overall wellness.

The Vitamin B12 Test measures cobalamin levels in blood to evaluate nutritional health, red blood cell production, and nervous system function. Low B12 can cause anemia, fatigue, weakness, memory problems, and nerve damage, while high levels may indicate liver or kidney disease. Doctors use this test to detect B12 deficiency, monitor treatment, and assess malabsorption conditions like pernicious anemia, Crohn’s disease, or celiac disease.

The Iron Total and Total Iron Binding Capacity (TIBC) Test measures iron levels in blood along with the blood’s ability to transport iron. It helps diagnose iron deficiency anemia, iron overload (hemochromatosis), and monitor nutritional or chronic health conditions. Low iron or high TIBC may indicate anemia, while high iron or low TIBC can suggest overload. Doctors use this test to evaluate fatigue, weakness, or other symptoms linked to iron and metabolic health.

The Ferritin Test measures ferritin, a protein that stores iron in the body, to evaluate iron levels and detect deficiency or overload. It helps diagnose anemia, iron deficiency, hemochromatosis, and chronic disease-related inflammation. Doctors often order the ferritin test to investigate fatigue, weakness, or unexplained symptoms. It is also used to monitor iron supplementation, treatment effectiveness, and overall iron metabolism health.

The Vitamin D 25-Hydroxy Total Test measures levels of 25-hydroxyvitamin D in blood to evaluate vitamin D status, bone health, and calcium balance. It helps detect deficiency, insufficiency, or toxicity, which can affect immune function, muscle strength, and risk of osteoporosis. Doctors use this test to assess overall nutritional health, monitor supplementation, and support diagnosis of metabolic or endocrine disorders linked to vitamin D.

The Fecal Globin by Immunochemistry Test detects hidden (occult) blood in stool using antibodies that identify human globin protein. This test helps screen for colorectal cancer, polyps, ulcers, and gastrointestinal bleeding. Doctors order it when patients have anemia, abdominal pain, or changes in bowel habits. Results provide early detection of digestive tract bleeding, guiding further evaluation with colonoscopy or other diagnostic procedures.

The Endomysial IgA Antibody Screen with Reflex to Titer Test measures IgA antibodies linked to celiac disease and gluten sensitivity. It supports evaluation of chronic diarrhea, abdominal pain, weight loss, or nutrient deficiencies tied to autoimmune activity. Reflex to titer enhances diagnostic clarity, providing valuable information about intestinal damage, immune health, and systemic conditions.
