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 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 (B2M) Test measures levels of B2M, a protein found on most cell surfaces and released into the blood. Elevated levels may indicate multiple myeloma, lymphoma, chronic infections, or kidney disease. Doctors order this test to evaluate cancer stage, prognosis, or kidney function. Results provide essential insight into disease progression, immune activity, and treatment monitoring for blood cancers and renal disorders.

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

The CA 19-9 Test measures levels of carbohydrate antigen 19-9 in blood, a tumor marker often elevated in pancreatic cancer and sometimes in bile duct, colorectal, or liver cancers. While not used alone for diagnosis, it helps monitor treatment, track disease progression, and detect recurrence. Elevated CA 19-9 may also occur in noncancerous conditions. Doctors use this test to support cancer management and guide therapy decisions.

 The Cadmium Blood Test is a laboratory test that measures the levels of cadmium in the blood. Cadmium is a heavy metal that is used in various industrial applications, including batteries, pigments, and metal coatings. While it has beneficial uses in industry, cadmium is toxic to humans when ingested, inhaled, or absorbed in significant amounts.
: Blood

The Cadmium Micronutrient Blood Test measures cadmium levels in the blood to assess exposure and potential toxicity. Cadmium, a heavy metal found in industrial environments, tobacco smoke, and contaminated food or water, can harm the kidneys, lungs, and bones. This test helps detect harmful exposure, guide treatment, and monitor health risks associated with cadmium accumulation.

Patient must be 18 years of age or older.

Also Known As: Cadmium Test


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 Insulin Resistance Panel with Score, Cardio IQ Test is a specialized panel of tests that is used to evaluate an individual's risk of insulin resistance, which is a precursor to type 2 diabetes. The results from these tests are combined to provide a score that represents the person’s risk level of insulin resistance.

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.

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

The Cardio IQ™ Lipoprotein Fractionation Ion Mobility Test separates and measures lipoprotein particles by size and concentration using ion mobility technology. It provides a detailed profile of LDL, HDL, and other subclasses, offering a clearer assessment of cardiovascular risk than standard cholesterol testing.

: Serum
Also Known As: LDL Particle Testing, LDL Subclass Test, LDL Fractionations Test

The NMR Lipoprotein Fractionation Test uses nuclear magnetic resonance to measure particle size and concentration of LDL, HDL, and VLDL cholesterol. Unlike a standard lipid panel, it provides detailed information on lipoprotein subfractions linked to cardiovascular risk. Doctors use this test to assess heart disease risk, guide cholesterol management, and monitor therapy effectiveness. It offers deeper insight into lipid metabolism and cardiovascular health.

Also Known As: NMR Test, LDL Particle Testing, LDL Subclass Test, LDL Fractionations Test

The Cardio IQ™ Lp-PLA2 PLAC® Test measures lipoprotein-associated phospholipase A2, an enzyme linked to vascular inflammation and plaque instability. Elevated levels are associated with increased risk of coronary heart disease and ischemic stroke. Doctors use this blood test to assess cardiovascular risk beyond standard cholesterol testing, helping guide prevention and treatment strategies to reduce risk of heart attack or stroke.

Also Known As: LpPLA2 Test, Ps-PLA2 Activity Test, Lipoprotein-Associated Phospholipase A2 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.
