 The Endomysial IgA Antibody Screen with Reflex to Titer test is a serologic assay used primarily to assist in the diagnosis of celiac disease. This test detects antibodies targeting the endomysium, which is a connective tissue layer that surrounds muscle fibers. A reflex to titer means that if the screening is positive, the lab will then measure the amount or "titer" of the antibodies present, which can give an indication of the severity or stage of the disease.
: Serum

The Erythropoietin (EPO) Test measures the level of erythropoietin, a hormone made by the kidneys that stimulates red blood cell production. It helps evaluate the cause of anemia, polycythemia, or other blood disorders, and can aid in assessing kidney function or monitoring certain treatments.

: Serum
Also Known As: Erythropoietin Test

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.
