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 Intrinsic Factor Blocking Antibody test is a laboratory analysis used to detect the presence of antibodies that block intrinsic factor. Intrinsic factor is a protein produced by cells in the stomach lining and is crucial for the absorption of vitamin B12 in the small intestine. Blocking antibodies can interfere with this process, leading to vitamin B12 deficiency and related health issues.
Also Known As: Intrinsic Factor Antibody test, IF Antibody Test, IF Antibody Type 1 Test, IF Antibody Type 2 Test,

The Iron Total and Total Iron Binding Capacity (TIBC) Test measures iron levels in blood along with the blood’s ability to transport iron. It helps diagnose iron deficiency anemia, iron overload (hemochromatosis), and monitor nutritional or chronic health conditions. Low iron or high TIBC may indicate anemia, while high iron or low TIBC can suggest overload. Doctors use this test to evaluate fatigue, weakness, or other symptoms linked to iron and metabolic health.

Also Known As: Serum Iron Test, Total Iron Binding Capacity Test, TIBC Test, UIBC Test

The Iron Micronutrient Test measures blood iron levels to evaluate nutritional status and detect deficiencies or excess. Iron is essential for hemoglobin production, oxygen transport, energy metabolism, and immune function. This test helps identify anemia, iron overload, absorption issues, or dietary imbalances, supporting diagnosis and management of overall health and vital body functions.

Patient must be 18 years of age or older.

Also Known As: Serum Iron Test, Serum Fe Test

The Iron Total Test measures the amount of iron in the blood, which is essential for producing hemoglobin and transporting oxygen. It helps diagnose iron deficiency anemia, iron overload conditions, and monitor nutritional status or response to treatment.

: Serum
Also Known As: Serum Iron Test, Serum Fe Test

The Mineral Micronutrients Test Panel measures minerals: Calcium, Chromium, Copper, Iron, Magnesium RBC, Manganese, Molybdenum, Selenium, and Zinc to assess nutritional balance and overall health. These minerals are essential for bone strength, metabolism, energy production, antioxidant defense, and immune function. The panel helps detect deficiencies, excesses, or absorption issues, guiding health management.

Patient must be 18 years of age or older.

 The Kappa/Lambda Light Chains, Free with Ratio test is a diagnostic tool used to measure the levels of free kappa and lambda light chains in the blood. In humans, antibodies (immunoglobulins) are made up of two heavy chains and two light chains. There are two types of light chains: kappa and lambda. While these light chains are typically attached to the heavy chains, small amounts are also found "free" in the blood, unattached.

The Lactic Acid Plasma test, commonly referred to simply as a lactate test, measures the level of lactic acid in the blood. Lactic acid is a byproduct of cellular metabolism, specifically when the body breaks down glucose for energy in the absence of adequate oxygen, a process known as anaerobic metabolism. Under normal conditions, lactic acid is rapidly cleared from the blood. Elevated levels can indicate that tissues are not receiving enough oxygen or there is an impairment in the body's ability to clear lactate.

Also Known As: Lactate Test, L-Lactate Test, Lactate Plasma Test, Lactate Blood Test

 The Qualitative Lactoferrin Stool test is a diagnostic tool that examines a stool sample for the presence of lactoferrin, an iron-binding protein found predominantly in white blood cells called neutrophils. Elevated levels of lactoferrin in the stool can indicate the presence of inflammation in the intestines.

The Lipase Test measures the level of lipase, an enzyme produced by the pancreas, in the blood. Elevated levels can indicate pancreatitis or other pancreatic disorders, while low levels may suggest chronic pancreatic damage.

: Serum
Also Known As: LPS Test

The Lipid Panel with Ratios Test measures seven key markers: total cholesterol, HDL, LDL, non-HDL cholesterol, triglycerides, Chol/HDL ratio, and LDL/HDL ratio. This advanced panel evaluates cardiovascular risk by assessing cholesterol balance and fat metabolism. Doctors use it to detect high cholesterol, atherosclerosis risk, and heart disease, and to monitor treatment. Often part of routine exams, it provides insight into long-term heart and metabolic health.

Also Known As: Lipid Profile Test, Cholesterol Panel Test, Lipid Blood Test

The Lp-PLA2 Activity Test measures the activity of lipoprotein-associated phospholipase A2, an enzyme linked to vascular inflammation. It helps assess the risk of cardiovascular disease, including heart attack and stroke, by identifying plaque instability in the arteries.

: Serum
Also Known As: LpPLA2 Test, Ps-PLA2 Activity Test, Platelet-activating Factor Acetylhydrolase Test, PAF-AH Test, PLAC Test, Lipoprotein-Associated Phospholipase A2 Test

The Magnesium Serum Test measures magnesium levels in blood to evaluate electrolyte balance, nerve and muscle function, and overall metabolic health. Abnormal levels may indicate kidney disease, malnutrition, gastrointestinal disorders, or uncontrolled diabetes. Low magnesium can cause weakness, cramps, or irregular heartbeat, while high levels may signal kidney dysfunction. Doctors use this test to diagnose deficiencies, monitor therapy, or assess chronic health conditions.

Also Known As: Mg Test, Mag Test

The Magnesium Micronutrient RBC Test measures magnesium levels within red blood cells, providing a more accurate assessment of long-term magnesium status than serum tests. Magnesium is vital for muscle and nerve function, energy production, bone strength, and heart health. This test helps detect deficiencies or imbalances from poor diet, absorption issues, or medical conditions, supporting overall wellness.

Patient must be 18 years of age or older.

Magnesium Red Bood Cell Test, Mg Test, Mag Test


A Magnesium RBC (Red Blood Cell) test measures the level of magnesium within the red blood cells. It provides a more accurate assessment of magnesium status in the body compared to a standard serum magnesium test, which measures magnesium levels in the blood plasma.

Also Known As: Magnesium Red Bood Cell Test, Mg Test, Mag Test

The Methylmalonic Acid (MMA) Blood Test measures methylmalonic acid levels in the blood. Elevated levels may indicate a vitamin B12 deficiency, since B12 is required to process MMA. This test helps detect early or hidden B12 deficiency, evaluate unexplained anemia, and identify certain metabolic disorders.

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
