Overview
Laboratory findings consistent with the diagnosis of myelodysplastic syndrome include abnormal complete blood count, peripheral blood smear, cytogenetic analysis, immunohistochemistry, and bone marrow biopsy.[1]
Laboratory Findings
Laboratory findings consistent with the diagnosis of myelodysplastic syndrome include abnormal complete blood count, peripheral blood smear, cytogenetic analysis, immunohistochemistry, and bone marrow biopsy.[1]
