PERIPHERAL BLOOD KARYOTYPING

Chromosome analysis (karyotyping) is the microscopic evaluation of metaphase chromosomes for numerical and structural abnormalities associated with disease. An expert cytogenetic technologist analyzes the banded chromosomes at a microscope. Digital images of representative cells are captured and the chromosomes are arranged in a standard format known as a karyogram. Peripheral blood is the most common specimen type referred for analysis.

Normal Male Karyotype (46,XY)

BONE MARROW & LEUKEMIC BLOOD CHROMOSOME ANALYSIS

Bone marrow and leukemic blood samples that contain spontaneously dividing cells usually are cultured short-term without mitogens. Some specimens with B-cell conditions are stimulated with mitogens. Chromosome analysis of the dividing cells is useful in the diagnosis and classification of hematological malignancies

Impression: Translocation(8;21) is seen in AML M2 mostly, also rarely in M1 or M4 and treatment related leukemia t-AML. Complete remission in most cases, but relapse is frequent. Median survival is about 1.5 years in adults.
