What does a haematologist do, and when should you see one?
A plain-language guide to what haematologists treat, which symptoms and test results often lead to a referral, and what to expect at a first visit.
What is a haematologist?
A haematologist is a doctor who specialises in conditions of the blood. That includes the red cells that carry oxygen, the white cells that fight infection, the platelets that help blood to clot, and the bone marrow where blood cells are made.
Conditions haematologists commonly see
- Anaemia, including iron deficiency and other causes of a low haemoglobin.
- Inherited blood conditions such as thalassaemia and sickle cell disease.
- Low or high platelet counts and other abnormal blood counts that need explaining.
- Bleeding and clotting problems.
- Conditions of the bone marrow and some blood cancers.
Reasons people are referred
A family doctor may suggest a haematologist when a blood test shows a result that needs a specialist opinion. Examples are a low haemoglobin that does not improve with treatment, a very high or low platelet or white cell count, or a family history of an inherited blood condition. Some people book a consultation because they would like a clearer explanation of their own reports.
What happens at a first consultation
The doctor will usually ask about your symptoms, past illnesses, medicines and family history. They will look at any reports you bring and may suggest further tests. Any diagnosis, medicine or treatment plan follows the doctor's own assessment of you.
How to prepare
- Collect your reports in date order.
- List the medicines and supplements you take, including doses.
- Write down your questions, so you do not forget them during the visit.
- Note any family history of blood disorders, early bleeding problems or clots.
When to get urgent help
Severe breathlessness, chest pain, fainting, heavy bleeding that does not stop, or sudden severe headache need emergency care. Do not wait for an appointment.
If you would like to discuss your own reports or symptoms, you can make a booking or read about the new consultation.
Frequently asked questions
Do I need a referral to see a haematologist?
Many patients are referred by a family doctor after an abnormal blood test, but you can ask the clinic about booking a first consultation directly.
Is a haematologist the same as an oncologist?
No. Haematologists look after blood, bone marrow and clotting conditions, including some blood cancers. Some doctors are trained in both, and the doctor will explain which care fits your situation.
