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 Helicobacter Pylori Antigen Stool Test detects H. pylori antigens in a stool sample to identify active infection in the stomach. It is commonly used to diagnose H. pylori, which can cause ulcers and gastritis, and to confirm eradication after treatment.

: Stool/Feces
Also Known As: H. Pylori Antigen Test, Stool Antigen Test

The Helicobacter pylori Urea Breath Test detects H. pylori infection in the stomach by measuring carbon dioxide in the breath after ingesting a urea solution. It helps diagnose infection and confirm eradication after treatment.

: Varied
Also Known As: H Pylori Breath Test

The Hemoglobin A1c with eAG Test measures average blood sugar levels over the past 2–3 months and provides an estimated average glucose (eAG) value for easier understanding. It is widely used to screen, diagnose, and monitor diabetes and prediabetes. Doctors use this test to evaluate long-term glucose control, adjust treatment, and reduce the risk of complications such as neuropathy, kidney disease, and heart problems linked to poor blood sugar management.

: Blood
Also Known As: A1c with eAG Test, HbA1c with eAG Test, Glycated Hemoglobin with estimated Average Glucose Test

The Hemoglobinopathy Evaluation test is a specialized laboratory assay designed to identify and characterize abnormal hemoglobin variants in the blood. Hemoglobinopathies are genetic disorders that result from alterations in the structure or production of hemoglobin molecules, leading to conditions such as sickle cell disease and thalassemia.
Also Known As: Hemoglobin Evaluation Test, Hb ELP Test, Hb IEF, Sickle Cell Screen Test, Hemoglobin Fraction Test, Hemoglobinopathies Test

: Blood

 The Hemogram and Differential test, more commonly known as the Complete Blood Count (CBC) with Differential, is a comprehensive blood test that provides information about various cells present in the blood. It measures the count, size, hemoglobin content, and other characteristics of red blood cells, white blood cells, and platelets.
: Blood

The Histamine Plasma Test measures histamine levels in the blood to help evaluate allergic reactions, mast cell disorders, or other conditions linked to abnormal histamine release. Elevated levels may indicate allergies, mastocytosis, or anaphylaxis, while low levels can affect digestive and immune function.

: Plasma-Unspecified Vial Pour

The HLA (Human Leukocyte Antigen) Typing for Celiac Disease test is a genetic test that identifies specific HLA gene variants associated with an increased risk of developing celiac disease. Celiac disease is an autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. This test aids in assessing the genetic predisposition to celiac disease.
: Blood
Also Known As: Tissue Typing Test, HLA Typing Test, Histocompatibility Test, HLA Crossmatching Test, HLA Screening Test

The IgE Test measures the level of immunoglobulin E (IgE) antibodies in the blood. Elevated IgE may indicate allergic reactions, asthma, or certain parasitic infections. This test helps identify potential allergies and supports the evaluation of immune system activity.

: Serum
Also Known As: Immunoglobulin E Test, Immunoglobulin E Antibody Test, IgE Antibody Test

The IgG Test measures immunoglobulin G (IgG), the most common antibody in the blood, which plays a key role in immune defense. Abnormal levels can indicate infections, immune deficiencies, or autoimmune disorders. This test helps evaluate immune system function and overall health.

: Serum
Also Known As: Immunoglobulin G Test, Immunoglobulin G Antibody Test, IgG Antibody Test

The IgG Subclasses Panel measures the four IgG antibody subclasses (IgG1, IgG2, IgG3, IgG4) in the blood. These antibodies play a key role in immune defense against infections. The test helps evaluate immune system function, detect subclass deficiencies, and investigate recurrent infections or certain immune-related conditions.

: Serum

The IgM Test measures immunoglobulin M (IgM) antibodies in the blood, which are the first antibodies produced in response to an infection. Elevated levels may indicate a recent or active infection, while low levels can suggest an immune deficiency. This test helps evaluate immune system function and detect infections.

: Serum
Also Known As: Immunoglobulin M Test, Immunoglobulin M Antibody Test, IgM Antibody Test

 The Immunofixation test, also known as Immunofixation Electrophoresis (IFE), is a laboratory procedure used to detect and identify abnormal proteins in the blood, especially monoclonal proteins (proteins produced by a single type of cell). The test involves separating proteins in a sample based on their size and electrical charge, and then exposing the separated proteins to antibodies specific to different protein types.
: Serum

: Random

The IgA Test measures immunoglobulin A (IgA) levels in the blood, an antibody that plays a key role in immune defense of the mucous membranes in the respiratory and digestive tracts. Abnormal levels may indicate immune deficiencies, chronic infections, autoimmune disorders, or liver disease.

: Serum
Also Known As: Immunoglobulin A Test, Immunoglobulin A Antibody Test, IgA Antibody Test

 The Immunoglobulins Panel test, also known as Total Serum Immunoglobulins test, is a comprehensive assessment of different types of immunoglobulins (antibodies) present in the blood. Immunoglobulins are proteins produced by the immune system to fight against infections and provide immunity. This panel measures the levels of various immunoglobulin classes: IgA, IgG, and IgM.
: Serum

 The Indican Urine Test, also known as the Obermeyer Test, measures the amount of indican in the urine. Indican (indoxyl sulfate) is a colorless compound that is formed when the amino acid tryptophan gets broken down by bacteria in the intestine. Once formed, indican travels to the liver, where it's typically converted into indoxyl and then excreted in the urine. High levels of indican in the urine can suggest an increased amount of protein decomposition in the gut or problems with normal digestion and absorption.

The Insulin Test measures insulin levels in blood to assess how the body regulates glucose and metabolism. It helps diagnose insulin resistance, hypoglycemia, type 2 diabetes, and metabolic syndrome. Doctors also use it to evaluate pancreatic function and monitor treatment effectiveness. Frequently ordered with glucose testing, the insulin test provides critical insight into endocrine health, blood sugar control, and risk for diabetes-related complications.

: Serum
Also Known As: Fasting Insulin Blood Test

: Serum

The Interleukin-6 (IL-6) Test measures levels of IL-6, a cytokine involved in inflammation and immune response. It helps assess infection, autoimmune disorders, chronic inflammatory conditions, and may aid in evaluating severity of diseases and conditions like sepsis

: Serum
Also Known As: IL-6 Test, Interleukin-6 Serum 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.

Celiac Disease 

This is an acute gluten sensitivity ... See more
