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

: Stool/Feces

: Blood
Also Known As: Retic Count Reticulocyte Percent Test, Reticulocyte Index Test, Corrected Reticulocyte Test, Reticulocyte Production Index Test, RPI Test
The reticulocyte count test is a laboratory test used to measure the number of reticulocytes in the blood. Reticulocytes are immature red blood cells that are released into the bloodstream from the bone marrow. This test provides valuable information about the production and maturation of red blood cells.

: Serum
Also Known As: RF Test, Rheumatoid Arthritis Factor Test
The Rheumatoid Factor (RF) test is a blood test that measures the levels of rheumatoid factor antibodies in the bloodstream. Rheumatoid factor is an antibody produced by the immune system, and its presence can indicate the presence of autoimmune conditions, particularly rheumatoid arthritis (RA). The RF test is commonly used as an initial screening tool for RA, although it is not specific to this disease.

 The Saccharomyces Cerevisiae IgA Antibodies test, often referred to as the ASCA (Anti-Saccharomyces Cerevisiae Antibodies) test, measures the concentration of IgA antibodies directed against the Saccharomyces cerevisiae yeast in the blood. Saccharomyces cerevisiae is a type of yeast used in baking and brewing.

: Serum
 The Saccharomyces Cerevisiae IgG Antibody test, commonly abbreviated as ASCA IgG, is a laboratory test used to detect the presence of IgG antibodies against Saccharomyces cerevisiae, a species of yeast. Saccharomyces cerevisiae is used in baking and brewing but can also serve as an antigen that triggers an immune response in certain individuals, leading to the production of ASCA IgG antibodies.

Also Known As: Erythrocyte Sedimentation Rate Test, ESR Test, Sedimentation Rate Test, Westergren Sedimentation Rate Test

The Sed Rate (Erythrocyte Sedimentation Rate) test, also known as the ESR test, is a laboratory test that measures the rate at which red blood cells settle to the bottom of a tube over a certain period of time. It is a non-specific test that provides information about the presence of inflammation in the body.


: Serum
Also Known As: 5-Hydroxytryptamine test, 5-HT test, Serotonin Serum Test
The Serotonin test, also known as a serum serotonin test, measures the concentration of serotonin—a neurotransmitter and hormone—circulating in the blood. Serotonin plays a crucial role in regulating mood, appetite, sleep, and various bodily functions. This test provides valuable insights into serotonin levels and their potential implications on both mental and physical well-being.

: Blood
Also Known As: Sickle Cell Test, Hemoglobin S Test, Hb S Test, Hgb S Test, Sickle Cell Blood Test
The Sickle Cell Screen test is a laboratory examination aimed at detecting the presence of abnormal hemoglobin, specifically hemoglobin S (HbS), which is characteristic of sickle cell disease (SCD) and other related hemoglobinopathies.

Also Known As: Free T3 Test, Free Triiodothyronine Test, FT3 Test, T3F Test, Unbound T3 Test

The T3 Free test measures the levels of free triiodothyronine (T3), an active thyroid hormone, in the blood. It assesses the unbound T3 that is available for immediate use by the body's cells.

: Serum
Also Known As: Free T4 Test, Free Thyroxine Test, FT4 Test, T4F Test, Unbound T4 Test

The T4 Free test measures the levels of free thyroxine (T4), an important thyroid hormone, in the blood. It assesses the unbound T4 that is available for immediate use by the body's cells.

 The Tissue Transglutaminase (tTG) IgA Antibody test is a blood test used to help diagnose celiac disease, an autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. This test measures the level of specific antibodies called IgA antibodies directed against tissue transglutaminase, an enzyme that plays a role in the body's response to gluten. The test is highly sensitive and specific for celiac disease and is often one of the initial tests performed when evaluating individuals suspected of having this condition.

: Serum
 The Tissue Transglutaminase IgG Antibody test is a specialized blood test used to diagnose and monitor celiac disease, an autoimmune disorder that affects the small intestine's ability to absorb nutrients from food. This test specifically measures the levels of IgG antibodies against tissue transglutaminase (tTG) in the blood.

: Serum
 The Trimethylamine N-Oxide (TMAO) test is a specialized diagnostic tool used to measure the levels of trimethylamine N-oxide in the blood. This test plays a significant role in assessing an individual's risk for cardiovascular diseases and guiding interventions to manage heart health.

Also Known As: Thyroid Stimulating Hormone Test, Thyrotropin Test

The TSH (Thyroid Stimulating Hormone) test measures TSH levels, a pituitary hormone that regulates thyroid function. It helps diagnose and monitor hypothyroidism, hyperthyroidism, and other thyroid disorders. Abnormal levels may indicate hormone imbalances and guide treatment decisions.

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
