Getting diagnosed with chronic lymphocytic leukaemia (CLL)

You usually start by seeing your GP if you have symptoms. Or your GP might arrange to see you if you have had an abnormal blood test result. They will ask you about any symptoms and examine you.

They will then decide whether to refer you for further tests or to a specialist. 

Seeing your GP

See your GP if you notice a change that isn't normal for you or if you have any of the possible signs and symptoms of chronic leukaemia.

Referral to a specialist for CLL

Your GP should refer you for an urgent blood test if your symptoms could be due to CLL.

Screening for CLL

There isn't a screening programme in the UK for chronic lymphocytic leukaemia (CLL). Read more about this. 

Tests for chronic lymphocytic leukaemia (CLL)

Your doctor can usually diagnose CLL by doing a number of checks on your blood sample cells. These are called immunophenotyping tests. You then may have other tests to find out more about the type of CLL you have. 

Genetic tests on your chronic lymphocytic leukaemia (CLL) cells

Your doctors will do tests on your blood and bone marrow to look for changes in certain genes.
