All Digestive System Tests

Specimen Type: Serum

The Immunoglobulin E (IgE) Test measures IgE antibody levels in blood to evaluate allergic reactions, asthma, and immune response. Elevated IgE may indicate allergies to food, pollen, or other triggers, as well as eczema or parasitic infections. Doctors order this test to investigate symptoms like hives, sneezing, or wheezing and to guide allergy treatment. Results provide vital insight into immune health, allergic sensitivity, and overall diagnostic care.

Specimen Type: Serum

The Immunoglobulin G (IgG) Test measures IgG antibody levels in blood to assess immune system function and long-term response to infections. Low IgG may indicate immune deficiencies or recurrent infections, while high levels may signal chronic inflammation, autoimmune disease, or certain infections. Doctors use this test to evaluate unexplained illness, monitor immune disorders, or assess overall immunity. Results provide vital insight into immune health and disease management.

Specimen Type: Serum

The IgG Subclasses Panel measures four IgG antibody subclasses (IgG1, IgG2, IgG3, IgG4) to assess immune system function. Abnormal levels may indicate primary immunodeficiency, recurrent infections, autoimmune disease, or allergic conditions. Doctors order this test for patients with chronic sinus, lung, or ear infections or suspected immune imbalance. Results provide key insight into antibody response, guiding diagnosis, treatment, and long-term immune monitoring.

Specimen Type: Serum

The Immunoglobulin M (IgM) Test measures IgM antibody levels in blood to evaluate immune response and early defense against infections. High IgM may indicate recent or acute infections, autoimmune disease, or certain blood disorders, while low levels may suggest immune deficiency. Doctors order this test to investigate recurrent infections, unexplained inflammation, or suspected immune problems. Results provide vital insight into antibody health, immune status, and diagnostic care.

Specimen Type: Serum

 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.

Specimen Type: Serum

Specimen Type: Random

The Immunoglobulin A (IgA) Test measures IgA antibody levels in blood to evaluate immune system health and mucosal defense in the respiratory and digestive tracts. Low IgA may indicate immune deficiency, celiac disease, or recurrent infections, while high levels may suggest autoimmune disorders, liver disease, or chronic inflammation. Doctors use this test to assess unexplained illness or immune imbalance. Results provide key insight into antibody function and overall immunity.

Specimen Type: Serum

The Total Immunoglobulins Panel measures IgA, IgG, and IgM levels to evaluate immune system function. Abnormal results may indicate immune deficiency, chronic infections, autoimmune disorders, or certain blood cancers. IgA helps protect mucous membranes, IgG provides long-term defense, and IgM is the body’s first response to infection. Doctors use this blood test to diagnose, monitor, and manage immune-related conditions and overall immune health.

Specimen Type: Serum

The Indican Urine Test measures indican, a byproduct of protein breakdown by intestinal bacteria. Elevated levels may indicate poor digestion, malabsorption, small intestinal bacterial overgrowth (SIBO), or gastrointestinal disorders. Doctors use this test to evaluate gut health, investigate symptoms like bloating, gas, or fatigue, and monitor treatment for digestive imbalances. It provides valuable insight into intestinal function, metabolism, and overall digestive health.

Specimen Type: Random

Specimen Type: Blood, Serum

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.

Specimen Type: Serum

Specimen Type: Serum

The Interleukin-6 (IL-6) Test measures levels of IL-6, a cytokine involved in immune response and inflammation. Elevated IL-6 may indicate infection, autoimmune disease, chronic inflammatory disorders, or certain cancers. Doctors order this test for patients with persistent fever, fatigue, or suspected sepsis. Results help assess inflammation severity, guide treatment, and monitor disease progression in autoimmune, infectious, or metabolic conditions.

Specimen Type: Serum

The Intrinsic Factor Blocking Antibody Test detects antibodies that interfere with intrinsic factor, a protein essential for vitamin B12 absorption. The presence of these antibodies is strongly associated with pernicious anemia, an autoimmune cause of B12 deficiency. Doctors use this blood test to help confirm diagnosis, distinguish the cause of anemia, and guide treatment for patients experiencing fatigue, weakness, or neurological symptoms related to low B12.

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.

Specimen Type: Serum

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.

Specimen Type: Serum

The Iron Total Test measures iron levels in blood to evaluate nutritional status, red blood cell production, and overall metabolic health. Abnormal levels may indicate iron deficiency anemia, chronic blood loss, or poor absorption, while high levels may suggest hemochromatosis, liver disease, or iron overload. Doctors use this test to investigate fatigue, weakness, or pallor and to monitor treatment. Results provide key insight into anemia and iron balance.

Specimen Type: Serum

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.

Specimen Type: Serum

Specimen Type: Random

The Kappa/Lambda Light Chains, Free with Ratio Blood Test measures free kappa and lambda light chains, proteins produced by plasma cells, and calculates their ratio. Abnormal results may indicate multiple myeloma, light chain amyloidosis, or related plasma cell disorders. Doctors use this test with serum protein electrophoresis and immunofixation to detect, diagnose, and monitor disease progression or treatment response in patients with suspected blood cancers.
