Test Catalog

Test ID: SZDIA    
Sezary Diagnostic Flow Cytometry, Blood

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This Sezary panel is ordered in cases of suspected Sezary syndrome or cutaneous T-cell lymphoma (CTCL) with peripheral blood involvement. For cases without a previously confirmed diagnosis of Sezary syndrome, a triage panel will also be performed to exclude a B-cell lymphoproliferative disorder.


A triage panel is always performed. The panel is charged based on number of markers tested (FIRST for first marker, ADD1 for each additional marker). In addition, reflex testing may occur to fully characterize a disease state or clarify any abnormalities from the screening test. Reflex tests will be performed at an additional charge for each marker tested (ADD1 if applicable).
