All Digestive System Tests

Order our digestive system tests to help diagnose intestine, colon, pancreas, and liver problems to achieve optimal gastrointestinal health.

Don't overlook your gastrointestinal health. With so much focus on cancer, heart attacks, and strokes, it's easy for your gut health to get lost in the shuffle.  However, it's important to have digestive lab tests done regularly. Catching digestive system conditions before they start is the best form of medicine.

The digestive system is a complex and vital part of the body and is responsible for breaking down food for energy or building blocks for cells. Digestive lab testing can provide insight into how the gastrointestinal tract functions and potentially diagnose ... 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.

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 is a specialized laboratory assay designed to measure the concentration of alpha-1-antitrypsin (AAT) in the blood. AAT is a protein primarily produced by the liver, and its main function is to inhibit the activity of enzymes that break down lung tissue, protecting the lungs from damage.

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 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 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.

Celiac Disease 

This is an acute gluten sensitivity ... See more
