WebCytochemical stains, which are enzymatic colorimetric reactions that occur in the cells of interest, were necessary to assign and confirm myeloid and lymphoid lineage. In the current WHO 2008 Classification of leukemia, immunophenotyping and cytogenetic analysis have largely replaced cytochemical staining in the characterization of acute leukemias. WebIt can be done on blood or bone marrow samples and can detect very small amounts of BCR-ABL, even when doctors can't find the Philadelphia chromosome in bone marrow cells with cytogenetic testing. PCR can be used to help diagnose CML. It's also useful after treatment to see if copies of the BCR-ABL gene are still there. ipratropium for eustachian tube dysfunction
