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 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.

The Fecal Globin by Immunochemistry Test detects human globin in stool using immunochemical methods. It is primarily used to screen for hidden (occult) blood in the stool, which may indicate gastrointestinal bleeding, colorectal cancer, or other digestive tract conditions.

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.

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.

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

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.

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

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.
