Test Overview
Direct immunofluorescence using flow cytometric techniques.
Confirmation of diagnosis and immunophenotype in cutaneous T-cell lymphoma. This test is used for phenotypic profiling of circulating T-cells in patients with known or suspected cutaneous T-cell lymphoma or quantitation and monitoring of aberrant T-cell populations in peripheral blood during or after treatment. This assay is not recommended for phenotypic profiling of other known or suspected T-cell lymphomas. See http://www.pathology.med.umich.edu/handbook/Tables/Flow_Cytometry_Panel… for all Flow Cytometry Panels.

<b>*Pediatric Reference Ranges from Journal of Allergy and Clinical Immunology, vol. 112, No. 5, 11/2003 and studies performed at Michigan Medicine Flow Cytometry Laboratory. Absolute ranges are calculated utilizing absolute lymphocyte count ranges for the same age groups provided by the hematology laboratory. </b>
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Requires an adequate number of viable cells for analysis. Improper collection or transport may result in decreased cell viability and cancellation of testing.
