All Digestive System Tests

“All Digestive System Tests” brings your core GI lab options into one place. A proactive plan starts by matching your question—infection, inflammation, bleeding, malabsorption, reflux/dyspepsia, or pancreatic issues—to the right stool, breath, and blood tests. Noninvasive stool markers (calprotectin/lactoferrin) help separate inflammatory bowel disease (IBD) from non-inflammatory causes like IBS. Pathogen PCR and C. difficile testing identify infections fast. For upper-GI concerns, H. pylori stool antigen or urea breath tests evaluate ulcer risk. Chronic diarrhea, weight loss, or greasy ... See more

The Celiac Disease Comprehensive Panel screens for celiac disease by measuring Tissue Transglutaminase (tTG) Antibody IgA and total IgA. If tTG IgA is positive, an Endomysial Antibody Screen IgA is added for confirmation. If IgA levels are low, tTG IgG is performed to ensure accurate detection. Doctors use this blood panel to identify gluten sensitivity, confirm diagnosis, and guide treatment for patients with suspected celiac disease.

Also Known As: Comprehensive Celiac Disease Panel, Celiac Disease Test

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 Absolute Lymphocyte Count Test quantifies lymphocytes in blood, expressing immunity status through an absolute cell count rather than relative percentage. It aids in diagnosing immune disorders, tracking viral infection recovery, or identifying early signs of hematologic disease. By distinguishing lymphocytosis and lymphopenia, this test provides clinicians insight into immune suppression, overactivation, or recovery phases in infections or immunocompromised states.

The Gastroenteritis Adenovirus Antigen Detection Test identifies adenovirus antigens in stool samples to confirm viral infection linked to acute gastroenteritis. Adenoviruses are a common cause of diarrhea, vomiting, and abdominal pain, especially in young children. By detecting viral antigens directly, this test provides rapid diagnostic insight, supporting clinical evaluation of gastrointestinal illness and infection control.

The Aldolase Test measures levels of aldolase, an enzyme involved in breaking down glucose for energy. Elevated levels may indicate muscle damage, muscular dystrophy, polymyositis, dermatomyositis, or certain liver diseases. Doctors use this blood test to help diagnose and monitor muscle disorders, evaluate unexplained weakness, and track treatment response. It is often ordered alongside CK and other enzyme tests for a complete evaluation of muscle health.

The Alpha-1-Antitrypsin Quantitative Test measures levels of alpha-1-antitrypsin (AAT), a protein that protects the lungs and liver from damage. Low levels may indicate alpha-1-antitrypsin deficiency, a genetic disorder linked to emphysema, COPD, and liver disease. Doctors use this test to investigate unexplained lung or liver problems, confirm hereditary AAT deficiency, and guide treatment or monitoring strategies for long-term health management.

The Amylase Test measures amylase enzyme levels in blood to evaluate pancreatic and digestive health. Elevated amylase may indicate pancreatitis, gallbladder disease, intestinal blockage, or salivary gland disorders, while low levels may suggest chronic pancreatitis or liver damage. Doctors order this test to investigate abdominal pain, nausea, or fever. Results provide vital insight into pancreatic function, digestive disorders, and overall metabolic health.

The Amylase Random Urine Test with Creatinine measures amylase excretion corrected for creatinine, ensuring accurate assessment of enzyme activity. Abnormal results may indicate pancreatitis, salivary gland disorders, pancreatic duct obstruction, or impaired kidney clearance. By examining both amylase and creatinine, this test supports evaluation of pancreatic function, renal health, and gastrointestinal enzyme balance.


The ANA Screen IFA with Reflex to Titer and Pattern Test detects antinuclear antibodies in blood to evaluate autoimmune activity. If positive, further testing identifies antibody concentration (titer) and fluorescence pattern, helping diagnose conditions like lupus, rheumatoid arthritis, or Sjögren’s syndrome. Doctors order this test to investigate symptoms such as joint pain, fatigue, rash, or swelling and to guide treatment for autoimmune and connective tissue disorders.

Also Known As: ANA Test, Antinuclear Antibody Screen Test

The ANCA Screen with MPO and PR3 with Reflex to ANCA Titer detects antineutrophil cytoplasmic antibodies linked to autoimmune vasculitis. By targeting myeloperoxidase (MPO) and proteinase 3 (PR3), this test helps evaluate conditions such as granulomatosis with polyangiitis or microscopic polyangiitis. It supports diagnosis, disease activity monitoring, and assessment of autoimmune inflammation.


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.

People tend to overlook their digestive health. With so much focus on cancer, heart attacks, and strokes, it's easy for your gut health to get lost in the shuffle. 

That's why it's vital to have digestive lab tests done regularly. Catching digestive system conditions before they start is the best way to treat them. 

If monitoring your gut health is new to you, don't worry. In this article, we're going to cover everything you need to know about your gut.  

Digestive System Conditions 

There are different kinds of gastrointestinal lab tests to monitor different enzymes and bacteria in your gut. The bacteria in your gut is known as "good bacteria." These bacteria need to maintain their presence in your stomach for the system to remain healthy in the long run. An unhealthy digestive system can give rise to the following conditions.
