Alternate Test Names:
Identifies: ZAP-70, a cytoplasmic protein ubiquitously expressed in T cells and NK cells, and in neoplasms derived from these cells. Most normal B cells do not express ZAP-70, but it is expressed in a variety of B cell non-Hodgkin lymphomas. Importantly, expression of ZAP-70 in chronic lymphocytic leukemia/small lymphocytic lymphoma strongly correlates with a lack in immunoglobulin gene mutation, and has been associated with an adverse prognosis.
