CD64

From haematologyetc.co.uk


Summary
CD64 is less specific than CD14 in the identification of monocyte lineage, but is more sensitive and can be useful in the characterisation of MPAL



Diagnostic Use
  • CD64 is less specific than CD14, but is reliably expressed in AML with monocytic differentiation either monoblastic or monocytic aml
  • CD64 is not expressed by normal neutrophIls, but is acquired following their activation and is consistently expressed by promyelocytic AML albeit at lower intensity than in monocytic AML
  • The expression of CD64 by monocytic-lineage cells means that it has particular use as an additional marker of myeloid lineage in cases of suspected mpal.
