<unk>  is diagnosed in a variety of ways. The diagnostic procedures confirm if there is leukemia present, the extent of the leukemia (how far it has spread), and the type of leukemia. The diagnostic procedures are similar for the different types of leukemias: * A bone-marrow aspiration and biopsy to look for and collect leukemia cells. In aspiration, a fluid sample is removed from the marrow. In biopsy, bone marrow cells are removed. Usually both procedures are performed at the same time and used together to help with diagnosis. *Tests called immunophenotyping and cytogenetic analysis are performed on the cells to further determine the type and subtype of leukemia. * A complete blood count, which is a measurement of size, number, and maturity of different blood cells in blood. * Blood tests may include blood chemistry, evaluation of liver and kidney functions, and genetic studies. * A spinal tap: a special needle is placed into the lower back into the spinal canal, which is the area around the spinal cord. Cerebral spinal fluid is fluid that bathes the child's brain and spinal cord. A small amount of cerebral spinal fluid is sent for testing to determine if leukemia cells are present.
