Test Name: CD24
Methodology: Flow Cytometry
Staining for CD24 detects mature granulocytes and normal mature and immature B-cells at all stages of maturation. It is also expressed in most mature B-cell and B-lymphoblastic neoplasm. In our laboratory this marker is used for defining (gating on) the mature granulocytes to assess for antigen loss as a part of the PNH analysis.
Testing for this antigen is typically performed as a part of the PNH analysis. For customized testing panels including this antigen, please contact the Medical Director of the Flow Cytometry laboratory.
