Test Name: CD15

Methodology: Flow Cytometry

Test Description

Staining for CD15 detects mature granulocytes and immature myeloid cells (excluding CD34+ blasts), as well as mature and immature monocytes. It may also be expressed by the leukemic blasts of some acute myeloid leukemia (AML). As co-expression of CD15 and CD34 is abnormal, this combination of markers may be used for minimal disease detection in AML.

Specimen Requirements

Testing for this antigen is typically performed as a part of the acute myeloid leukemia add-on panel. For customized testing panels including this antigen, please contact the Medical Director of the Flow Cytometry laboratory.

Storage and Transport
