Getting diagnosed
It can be hard for GPs to decide who may have leukaemia and who might have a more minor condition just based on symptoms. Minor conditions are common and leukaemia is rare. So it would not be the first diagnosis that comes to mind when you are in your GP surgery.
For symptoms of ALL, your GP should arrange for you to have a blood test or see a blood specialist. You usually see a haematologist. This is a doctor that specialises in treating blood conditions, including leukaemia. Depending on your symptoms and other factors, this might be an urgent referral. You will see a haematologist as soon as possible. Ask your GP when this is likely to be.
Your doctor may ask you to wait to see if the symptoms get better with treatment, such as antibiotics. This is not uncommon. The important thing is to go back to your GP if you’re not getting better.
There are guidelines for GPs to help them decide who needs a referral to see a specialist.
Your GP will use these guidelines as well as their experience and judgement.
Some of the guidelines have targets around how quickly you are referred. For example, you might have blood tests within 2 days. Or you may see a specialist immediately (within a few hours).
These guidelines vary slightly between the different UK nations.

Go to the risks and causes of ALL
Go back to your GP if your symptoms have not improved, are getting worse or are happening more often.
If you feel your GP is not taking your symptoms as seriously as you'd like, print this page and take it along to the appointment. Ask your GP to explain why they think you should or shouldn’t have a referral.

If your GP suspects you have leukaemia you generally have tests to see a specialist quite quickly. This is usually within a few hours or days. Ask your GP when you should get your appointment and contact them again if you don’t get one. Some hospitals have a referral service you could try contacting if you know which hospital you are going to. Explain that you are waiting for an urgent suspected cancer referral for leukaemia.

Your hospital is working towards waiting time targets. For example, a target to find out whether you have cancer or not. And there are targets to start treatment if you are diagnosed with cancer. These are slightly different depending on where you live in the UK.

Acute lymphoblastic leukaemia is a type of blood cancer. It starts from young white blood cells called lymphocytes in the bone marrow.
The symptoms of ALL include feeling tired, frequent infections, high temperature and bruising easily. Find out more.
Your doctor may suspect ALL from a blood test. You then have more tests such as a bone marrow and scans to diagnose and find out more about ALL.
