CHROMOSOME TESTING FOR HEMATOLOGIC DISORDERS

Click to zoomCytogenetic analysis of bone marrow and oncology blood is indicated for individuals with a medical history suggestive of a hematologic disorder (leukemias and lymphomas). Microscopic examination of both chromosome number and structure is routinely performed on 20 metaphase cells. Additional metaphases will be studied if needed. Whenever possible, two or more G-banded karyograms are created by computer image analysis for each patient.
