What is the Cytochemistry Panel for Leukemias?

The Cytochemistry Panel is a set of laboratory tests that use special stains to differentiate various types of leukemia cells based on their chemical composition.


Why is this test performed?

This test is used to classify different types of leukemia, including acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL), which helps determine the appropriate treatment plan.


How is the test conducted?

A bone marrow or blood sample is stained with specific dyes (such as myeloperoxidase, Sudan Black B, and PAS) and examined under a microscope to assess cellular characteristics.


What do abnormal results indicate?

Abnormal staining patterns help differentiate between myeloid and lymphoid leukemia subtypes. For example, positive myeloperoxidase staining suggests AML, while positive PAS staining is seen in ALL.


What are the next steps if leukemia is diagnosed?

If leukemia is diagnosed, further genetic testing, immunophenotyping, and imaging may be needed to determine the best treatment approach, which may include chemotherapy, targeted therapy, or stem cell transplantation.
