Coronavirus: haematology update

In response to the coronavirus (COVID-19) outbreak, please read our advice and information before attending the service.


You will be offered an appointment within six weeks of being referred. At the end of your visit, we aim to give you a diagnosis and discuss treatment options.

Clinic locations

  • Specialist clinics and day unit

    Specialist clinics

    You will usually be seen in one of our specialist clinics if: 

    • you already have a particular diagnosis
    • there is a high suspicion of a particular diagnosis
    • have been referred from another hospital.

    At these clinics, you will see haematology specialists as well as other specialists, e.g. from the cancer or radiology teams.

    The haematology day unit

    Urgent cases are seen in the haematology day unit. The unit has six beds, one isolation room with ensuite facilities and two procedure rooms. It is open Monday-Friday, 9am-5pm.

  • Cancelling or changing your appointment

    If you need to cancel your appointment in office hours (9am-5pm, Monday-Friday), please call 020 7188 2724. Outside office hours, please email

    You can also email to rearrange your appointment or to check your appointment time. Please specify your name, surname and hospital number. A member of staff will reply to you via email by the next working day.

  • What to expect at your appointment

    Please arrive 15 minutes before your appointment time and be ready to produce a urine sample. We will perform some blood tests before you are seen by someone in our team. Straightforward appointments will take about an hour. If your condition is more complex, it could take several hours.

    The range of investigations you are likely to need include:

    • urine tests
    • blood tests
    • x-rays.

    You may also have:

    • a bone marrow biopsy
    • a CT or MRI scan
    • a venesection (taking a pint of blood).

    If any tests are needed before you see us, we will send you the relevant information before your appointment.

    Please be advised if you arrive twenty minutes late for your appointment you may not be seen.

  • After your appointment

    At the end of your visit, you can expect to receive a diagnosis and discuss any treatment options. We can send you a copy of the letter we will send to your GP if you wish.

  • If you need to stay overnight

    If you need to stay in hospital overnight for a procedure or treatment, you will stay on Samaritan Ward or Hedley Atkins Unit at Guy's. Occasionally, patients might be admitted to another ward.

    Both wards offer single sex accommodation and are staffed by health care professionals with specialist knowledge and experience in haematology.
