Area of Science:

  • Hematology
  • Cytochemistry
  • Oncology

Background:

  • Acute myeloid leukaemias (AML) diagnosis often relies on esterase cytochemistry.
  • Conventional methods require double incubation and multiple reagents, increasing complexity and time.

Purpose of the Study:

  • To evaluate a simplified single-incubation esterase cytochemistry method.
  • To assess its efficacy in diagnosing and classifying acute myeloid leukaemias, particularly monocytic lineage cells.

Main Methods:

  • Evaluation of Swirsky's single-incubation method on blood and bone marrow smears.
  • Comparison with conventional double-incubation techniques.

Main Results:

  • The Swirsky method requires only a single incubation and coupling reagent.

  • It demonstrates a strong positive reaction for butyrate esterase.
  • The method is effective in identifying cells of monocytic lineage.

    • Conclusions:

    • The single-incubation esterase method offers a more efficient alternative for AML diagnosis.
    • Its ability to clearly demonstrate monocytic cells provides a significant advantage over conventional techniques.
