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 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.

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.

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.

: Serum
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

The Carnitine test is a specialized laboratory assay designed to measure the concentration of carnitine—a vital compound—in the blood. Carnitine plays a crucial role in the transport of fatty acids into the mitochondria, the energy-producing centers of cells. This test offers insights into carnitine deficiency and metabolic abnormalities that affect energy metabolism.

 The carotene test is a blood test that measures the level of carotene in the serum. Carotene, which includes alpha-carotene and beta-carotene, is a type of antioxidant that belongs to the class of pigments called carotenoids. These pigments are responsible for the yellow, orange, and red colors in many fruits and vegetables. Once ingested, the body can convert certain carotenoids, particularly beta-carotene, into vitamin A, which plays a critical role in vision, growth, and immune system functions.

The CBC with H/H, RBC, Indices, WBC and Platelets Test evaluates overall blood health by measuring hemoglobin, hematocrit, red blood cell count, size and indices, white blood cell levels, and platelets. It helps detect anemia, infections, clotting disorders, and immune or bone marrow conditions. Frequently ordered in routine exams, this test supports diagnosis, monitoring of chronic disease, and assessment of general health.

The CEA Test measures carcinoembryonic antigen levels in blood, a protein that may be elevated in certain cancers, especially colorectal, pancreatic, lung, breast, or ovarian cancer. It is not used alone for diagnosis but helps monitor cancer treatment, detect recurrence, and track disease progression. Elevated CEA can also occur in noncancerous conditions. Doctors use this test to support therapy decisions and provide insight into cancer management.

Also Known As: Carcinoembryonic Antigen Test

The Ceruloplasmin Test measures levels of ceruloplasmin, a copper-carrying protein made in the liver, to evaluate copper metabolism and related disorders. Low levels may indicate Wilson’s disease, Menkes disease, or severe liver disease, while high levels may suggest inflammation or pregnancy. Doctors order this test for patients with liver problems, neurological symptoms, or abnormal copper levels. Results help diagnose metabolic disorders and guide treatment.
