Usually you will see your GP, who will examine you and arrange a blood test. If the results of the test suggest you may have leukaemia, your GP or a haematologist from the local hospital will contact you. A haematologist is a doctor who specialises in the treatment of blood problems. They will arrange for you to be seen quickly at the hospital for further tests and treatment.
At the hospital
Most people with ALL are referred for treatment at a specialist haematology unit in the hospital. The haematologist will ask you about your general health and any previous medical problems. They will examine you and do a blood test to check the numbers of all the different types of blood cell.
If the blood test shows leukaemia cells in your blood, the haematologist will want to take a sample of your bone marrow. This is the most important test for diagnosing ALL. It shows the exact type of leukaemia you have and provides information that the doctors need to plan the best treatment for you.
