| Note: | Results should be utilized in conjunction with other clinical and laboratory data to assist the clinician in patient management decisions. False negative results could occur in patients who have granulocytopenia due to bone marrow depression. Results may not be clinically applicable to children less than two years of age who have mildly increased fecal Calprotectin levels. There is a potential for elevated Calprotectin test results when measuring bloody stool samples. Other intestinal diseases, including many gastrointestinal infections and colorectal cancer, can result in elevated levels of Calprotectin. |
| When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent. | |
