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 Aldolase test measures the level of aldolase, an enzyme found in various tissues throughout the body, particularly in muscles and the liver. Aldolase plays a crucial role in glycolysis, a process that breaks down glucose for energy production.

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.

Also Known As: Alpha1-antitrypsin Test, A1AT Test, AAT Test, Alpha 1 Antitrypsin Serum Test

The Amylase Test measures the level of amylase, an enzyme produced by the pancreas and salivary glands, in the blood. Elevated levels can indicate pancreatitis or other pancreatic disorders, while low levels may suggest chronic pancreatic damage or other conditions affecting enzyme production.

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 test is a specialized blood test used to detect the presence of antineutrophil cytoplasmic antibodies (ANCA) in the bloodstream. ANCA are autoantibodies that target specific proteins found in the cytoplasm of neutrophils, a type of white blood cell. This test is a two-step process that includes an initial ANCA screen, followed by an ANCA titer test if the screen is positive.

 The ANCA (Anti-Neutrophil Cytoplasmic Antibodies) Vasculitides test identifies the presence of autoantibodies in the blood that target proteins found in the cytoplasm of neutrophil granulocytes, a type of white blood cell. These autoantibodies are associated with certain forms of vasculitis, a group of disorders characterized by the inflammation and damage of blood vessels. The test is typically comprised of two main types: c-ANCA (cytoplasmic) and p-ANCA (perinuclear).

The Beta-2-Microglobulin Serum Test measures levels of beta-2-microglobulin, a protein found on most cells. Elevated levels may indicate kidney dysfunction, immune system activity, or certain cancers such as multiple myeloma or lymphoma. It helps in diagnosis, monitoring disease progression, and assessing treatment response.

The C-Peptide Test measures C-peptide levels in blood to assess insulin production and pancreatic function. Low levels may indicate type 1 diabetes or reduced insulin production, while high levels may suggest type 2 diabetes, insulin resistance, or insulinoma. Doctors use this test to differentiate diabetes types, monitor treatment, and evaluate unexplained hypoglycemia. It provides key insight into endocrine, pancreatic, and metabolic health.

Also Known As: Connecting Peptide Insulin Test, Proinsulin C-Peptide Test

 The C-Peptide Response to Glucose, 2 Specimens test is a diagnostic procedure used to assess the body's ability to produce insulin in response to a glucose challenge. It involves measuring C-peptide levels in the blood before and after the administration of glucose. C-peptide is a byproduct of insulin production, making it an indirect marker of insulin secretion.

 The C-Peptide Response to Glucose test is a comprehensive assessment of insulin secretion by the pancreas in response to glucose ingestion. This test involves obtaining blood samples at multiple intervals after glucose consumption to analyze the levels of C-peptide, a byproduct of insulin production.

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 High-Sensitivity C-Reactive Protein (hs-CRP) Test measures very low levels of CRP in blood to evaluate inflammation and cardiovascular risk. Elevated hs-CRP may indicate increased risk for heart disease, heart attack, or stroke even before symptoms appear. Doctors use this test along with cholesterol and other markers to assess overall heart health, guide prevention strategies, and monitor treatment. It also helps evaluate chronic inflammation and metabolic conditions.

Also Known As: Cardiac CRP Test, High Sensitivity C-Reactive Protein Test


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.
