The Calprotectin Stool Test measures calprotectin, a protein released during intestinal inflammation, to help distinguish inflammatory bowel disease (IBD) such as Crohn’s disease and ulcerative colitis from irritable bowel syndrome (IBS). Doctors order this test for patients with chronic diarrhea, abdominal pain, or rectal bleeding. Results provide valuable insight into gut health, disease activity, and the need for further testing or treatment monitoring.

The Lactoferrin Qualitative Stool Test measures lactoferrin in stool to assess intestinal inflammation. Positive results may signal inflammatory bowel disease, including Crohn’s disease or ulcerative colitis, while negative results often suggest non-inflammatory conditions. This test supports evaluation of gastrointestinal health, immune activity, and disorders affecting digestive function.

The Saccharomyces cerevisiae IgA Antibodies Test detects IgA antibodies against baker’s or brewer’s yeast, often elevated in Crohn’s disease. This test helps distinguish inflammatory bowel disease from ulcerative colitis and other gastrointestinal disorders. Doctors use results with clinical evaluation and other markers to aid diagnosis, monitor disease activity, and guide ongoing management of digestive and autoimmune health conditions.

The Tumor Necrosis Factor-Alpha (TNF-α) Test measures levels of this cytokine, a key marker of inflammation and immune system activity. Elevated TNF-α may indicate autoimmune disease, chronic inflammation, sepsis, or certain cancers. Doctors order this test for patients with rheumatoid arthritis, Crohn’s disease, or persistent fever. Results provide critical insight into immune dysregulation, disease progression, and response to anti-inflammatory therapies.

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 ANCA Screen with Reflex to ANCA Titer detects antineutrophil cytoplasmic antibodies, often linked to autoimmune vasculitis such as granulomatosis with polyangiitis and microscopic polyangiitis. If the screen is positive, a titer is performed to measure antibody levels for greater diagnostic accuracy. Doctors use this test to evaluate unexplained inflammation, kidney or lung issues, and guide treatment decisions in autoimmune and systemic vasculitis care.

The Saccharomyces cerevisiae IgG Antibodies Test measures IgG antibodies against baker’s or brewer’s yeast, often associated with autoimmune and gastrointestinal disorders. Elevated IgG levels are commonly linked to Crohn’s disease and may help differentiate it from ulcerative colitis. This test supports evaluation of immune response, gastrointestinal inflammation, and monitoring of conditions tied to yeast-related antibody activity.

The Celiac Disease Comprehensive Panel for Infants measures antibodies linked to gluten sensitivity and autoimmune activity. It includes tissue transglutaminase (tTG), deamidated gliadin peptide (DGP), and total IgA to support detection of early immune reactions. By identifying abnormal antibody patterns, this panel helps evaluate gluten intolerance, malabsorption, and celiac risk in infants.

The Cardio IQ™ hs-CRP Test measures high-sensitivity C-reactive protein in the blood to assess inflammation linked to cardiovascular risk. Elevated levels may indicate a higher risk of heart disease or other inflammatory conditions.
