Malabsorption Evaluation Panel, Feces
Use
The Malabsorption Evaluation Panel is utilized for the assessment of patients suspected to have malabsorption conditions. This test is significant in evaluating cases of chronic diarrhea, unexplained weight loss, or nutritional deficiencies. It helps differentiate between causes like inflammatory conditions, pancreatic insufficiency, and osmotic diarrhea. Moreover, it is employed to detect protein-losing enteropathy that could be linked to underlying malabsorption conditions. As a comprehensive stool-based assessment, it provides insights into GI function directly, by evaluating the levels of calprotectin, pancreatic elastase, and the presence of reducing substances, which collectively aid in the diagnosis and management of various malabsorption scenarios.
Special Instructions
Not provided.
Limitations
This panel is designed to identify the presence and potential causes of malabsorption but does not specifically diagnose the exact etiology. Certain factors such as improper specimen handling and heterogeneous composition of fecal material can introduce variability in test results. Furthermore, testing cannot be appended to previously collected specimens and must involve freshly collected and immediately processed samples. The diversity in malabsorption causes necessitates corroborative evaluations and clinical diagnostics for the accurate identification and management of the condition.
