In this article, we will discuss the Immunophenotyping in Acute Leukemia. So, let’s get started.
Immunophenotyping
The recent development of monoclonal antibodies as well as advances in flow cytometry has made immunophenotyping readily available. It is useful in:
- Definite lineage (B cell versus T cell) and stages of differentiation of ALL and identifying characteristic features of AML
- Aiding in lineage determination of acute leukemias that are morphologically undifferentiated
- In differentiating acute leukemias from other non-hematological disorders
- Recognising mixed lineage/biphenotypic acute leukemia (ALL with myeloid markers or AML with lymphoid markers)
