Cytogenetic Analysis in Acute Myeloid Leukaemia

Cytogenetic analysis is an integral part of the diagnostic work-up of the patient with acute myeloid leukaemia. Conventional cytogenetic analysis relies on obtaining a good quality bone marrow specimen in a timely fashion and setting up at least two short-term cultures. A 15–24-h culture and a 48-h synchronised culture are routinely set up but as the cytogenetics result is often required urgently to determine the type of therapy to be administered, analysis is undertaken using the overnight culture in the first instance. Rapid and accurate analysis relies on obtaining high-quality G-banding. Knowledge of the conditions affecting banding is therefore essential.
