The Haematology, Blood Transfusion and Immunology department provides a high quality analytical service and clinical advice. We receive in excess of 519,000 specimens per year, on which we perform over 799,000 tests. The service is consultant-led with 70 medical, scientific and support staff and comprises four sections:
*The Saturday/Sunday/Bank Holiday service offered by all departments is intended for essential work.
Urgent work will be processed at any time. The Biomedical Scientist (BMS) on call for each department may be contacted through the RCHT Hospital switchboard (01872 250000).
Please phone the laboratory if results are needed immediately or for blood products that are needed urgently.
Out of hours, do not bleep the BMS unless very urgent or for a cross match/blood product issue, or advice.
The routine Haematology service analyses samples, which includes the following:
The Coagulation service includes testing for basic coagulation screen.
The Andrology service includes semen testing.
The Blood Transfusion department offers:
Each year, we supply around 16,000 units of red blood cells, as well as platelets, plasma and other blood products, to patients at both the Royal Cornwall Hospitals and the Community Hospitals in Cornwall.
In the UK, we have rigorous regulations regarding blood donations and blood transfusions to minimise the risk of being given blood that is contaminated with a virus, or from an unsuitable blood group. Compared to other everyday risks, the likelihood of getting an infection from a blood transfusion is very low. All blood donors are unpaid volunteers and they’re very carefully selected and tested to make sure that the blood they donate is as safe as possible.
If you’re going to have a blood transfusion, we’ll ask you to wear an identification band with your details on to make sure you get the right transfusion. We’ll check this each time you receive a new bag of blood, and we’ll also ask you your full name and date of birth to double check.
If your doctor suggests you need a blood transfusion, you can find more information on the NHS Blood and Transplant website.
If you have recently had a transfusion and feel unwell, please read our patient information leaflet and get in touch with your doctor.
The immunology service based at Derriford offers testing to investigate disorders of the immune system, including:
When an add-on test has been requested but testing not possible this will be reported. Within RCH the original MAXIMs form should be printed (do NOT create a new MAXIMs request), the add-on test hand written on and the form sent to the laboratory.
Samples for group & screen/cross match are valid for a maximum of 7 days; however, this is affected by the patient’s transfusion and obstetric history. Regularly transfused patients may need samples taken more frequently – please contact the laboratory on ext. 2500 if you are unsure. Advice is also available on the reverse of the request form.
Wherever possible, the cause of anaemia should be investigated and where a reversible cause is identified, this should be corrected before resorting to transfusion
Antenatal testing: Screening should test all mothers twice in pregnancy, at booking and a second time in the 28th week of gestation for ABO and Rh (D) groups and antibody screening. If any further testing is required as a result of these tests, a report will be issued suggesting appropriate follow-up tests and their timing.
All Rh (D) negative mothers, who do not have immune anti-D, should be offered anti-D prophylaxis. This is an essential part of the management of Rh (D) negative women. A standard dose of 1500iu should be administered at 28 weeks gestation after the samples for the routine screen have been taken and after any potentially sensitising event.
