Ordering RecommendationRecommendations when to order or not order the test. May include related or preferred tests.
Use to identify eosinophil involvement/eosinophil-related inflammation by staining for the eosinophil granule core protein, major basic protein 1 (eMBP1), and/or the eosinophil granule matrix protein, eosinophil-derived neurotoxin (EDN) in order to detect cellular localization and extracellular deposition.
Eosinophil granule proteins are toxic to tissues and cells and may be pathogenic in disease but may not be recognized when deposited outside of morphologically-identifiable intact eosinophils.
