Overview
Other Diagnostic Studies
Biopsy
A biopsy is the only sure way to know whether leukemia cells are in your bone marrow. Before the sample is taken, local anesthesia is used to numb the area. This helps reduce the pain. Doctor removes some bone marrow from hipbone or another large bone. A pathologist uses a microscope to check the tissue for leukemia cells.
Cytogenetics
The lab looks at the chromosomes of cells from samples of blood, bone marrow, or lymph nodes. If abnormal chromosomes are found, the test can show what type of leukemia you have. For example, people with CML have an abnormal chromosome called the Philadelphia chromosome.
Spinal Tap
Doctor may remove some of the cerebrospinal fluid (the fluid that fills the spaces in and around the brain and spinal cord). The doctor uses a long, thin needle to remove fluid from the lower spine. The procedure takes about 30 minutes and is performed with local anesthesia. The lab checks the fluid for leukemia cells or other signs of problems.
