Testing Algorithm

This Sezary panel is ordered for patients with previously diagnosed Sezary syndrome or cutaneous T-cell lymphoma (CTCL) with peripheral blood involvement.

 

For patients with a clinical suspicion of Sezary syndrome, but no previously confirmed diagnosis or immunophenotyping performed in our laboratory, order SZDIA / Sezary Diagnostic Flow Cytometry, Blood. A triage panel will also be performed to evaluate for and exclude monotypic B cells or increased blasts.

 

The panel is charged based on number of markers tested (FIRST for first marker, ADD1 for each additional marker).
