Bone marrow trephine report showed 80% blast cells on peripheral blood with heterogenous population of blast cells and suppressed haematopoiesis.
Identification of blast cells was performed using side scatter (SSC) versus CD45 intensity and SSC versus forward scatter (FSC) parameter dot plots.
The post-chemotherapy increase in peripheral blasts can be generally applied to the post-transplantation laboratory results to reflect that as a patient's new marrow (donor marrow) begins to produce white blood cells, sometimes immature or blast cells are pushed out into the peripheral blood as well.
Plenty nucleated red blood cells and many mature and immature leucocytes including predominantly myelocytes with number of the blast cells form 6% to 30% were present in the chronic, accelerated phases and blast crises were seen while bone marrow smear were showing hypercellularity due to excessive proliferation of myeloid cell line predominantly of myelocytes hypolobated megakaryocyts with few blue histocytes and pseudogaucher cell.
CMML is a life-threatening hematologic malignancy characterized by elevated levels of monocytes, immature blood cells, or blast cells, and abnormal cells in the peripheral blood as well as in the bone marrow.
Several investigations support presence of blast cells in mollusk haemolymph circulation.

Precursor cells from myeloid blast cells through to metamyelocytes were counted together as immature granulocytes.
The chronicity of the disease, persistence of leukocytosis in the peripheral blood, lack of evidence of neoplasia in nonhemic tissue, and lack of blast cells in the peripheral blood or bone marrow support a diagnosis of CML.
