Leukostasis (also called symptomatic hyperleukocytosis) is a medical emergency most commonly seen in patients with acute myeloid leukemia.It is characterized by an extremely elevated blast cell count and symptoms of decreased tissue perfusion.
Immunophenotyping is a very common flow cytometry test in which fluorophore-conjugated antibodies are used as probes for staining target cells with high avidity and affinity. This technique allows rapid and easy phenotyping of each cell in a heterogeneous sample according to the presence or absence of a protein combination. [1]
