Test Overview
Test Methodology

Direct immunofluorescence using flow cytometric techniques.

Test Usage

Confirmation of diagnosis and immunophenotype of mast cell disorders. Phenotypic profiling of mast cells in bone marrow as an adjunct to client's morphological evaluation. See http://www.pathology.med.umich.edu/handbook/Tables/Flow_Cytometry_Panel… for all Flow Cytometry Panels.

Reference Range *

Pathologist interpretation of results provided.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
