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.
