CPT® Code 83630

Lactoferrin is a glycoprotein that binds iron and is primarily found in the granules of neutrophils, a type of white blood cell (WBC). The CPT® Code 83630 refers to a qualitative test that detects the presence of lactoferrin in fecal samples. This test is significant because the presence of lactoferrin in stool is indicative of inflammatory processes within the gastrointestinal tract. Specifically, it serves as a marker for inflammatory diarrhea, which can be caused by various conditions such as bacterial infections, ulcerative colitis, or Crohn's disease. To perform this test, a stool sample is collected following a bowel movement and is analyzed using a qualitative enzyme-linked immunosorbent assay (ELISA). This method allows healthcare providers to determine whether lactoferrin is present, thereby aiding in the diagnosis of inflammatory bowel diseases. In contrast, CPT® Code 83631 pertains to a quantitative test that measures the concentration of lactoferrin in the stool, providing further insights into the severity of inflammation and the effectiveness of treatment in patients with inflammatory bowel disease.
