CPT® Code 83631

Lactoferrin is a glycoprotein that binds iron and is primarily found in the granules of neutrophils, a type of white blood cell (WBC). The presence of lactoferrin in feces is significant as it serves as a biomarker for inflammatory conditions affecting the gastrointestinal tract. Specifically, the measurement of lactoferrin levels can indicate the presence of inflammatory diarrhea, which may be caused by various conditions such as bacterial infections, ulcerative colitis, or Crohn's disease. The test associated with CPT® Code 83631 is a quantitative assessment, meaning it measures the concentration of lactoferrin in a stool sample, providing more detailed information than a qualitative test. This quantitative analysis is particularly useful for differentiating between inflammatory and non-inflammatory bowel diseases, thereby aiding in the diagnostic process. Additionally, it can be instrumental in monitoring the effectiveness of treatment in patients diagnosed with inflammatory bowel disease, allowing healthcare providers to make informed decisions regarding patient care and management.
