What is the location of the laboratory?

 

The Blood Transfusion Laboratory is located on the 5th Floor of the Royal Derby Hospital. 

 

What services are offered by the laboratory?

 

The department is CPA Accredited , MHRA  compliant, meets current BCSH Guidelines  and participates in all relevant Quality Assurance schemes. The following tests are available:  ABO and RhD grouping, Antibody screening / identification, Compatibility testing including serological crossmatch and electronic issue, Neonatal sample testing, Kleihauer testing and Direct Antiglobulin testing. In addition the department provides routine Ante Natal Anti-D prophylaxis ( RAADP).

 

What are the opening times of the laboratory?

 

The Transfusion department operates 24 hours for the receipt of samples. The core-time for all laboratories within the hospital is 08.45 through to 17.15, Monday to Friday, when all services are available.

 

What is the availability of clinical advice and interpretation and how do I obtain it?

 

Clinical advice for all aspects of Transfusion  can be obtained from a Consultant Haematologist  or the Trust Transfusion  Practitioners  

 

How do I complete a request form?

Each sample sent to the transfusion  laboratory must be accompanied by the relevant request form. It is vital that the sample and  form match identically with the minimum patient  identification to include surname /family name (correctly spelt), first name (in full), date of birth ( not age or year of birth), hospital number/NHS number. Failure to complete request forms and samples correctly can lead to significant delays or  worse case scenario lead  to ABO-incompatible transfusions. Written policies for generating blood transfusion requests and for the collection of blood samples are available in the Trust Transfusion Policy.  It is the responsibility of the requesting medical officer or authorised practitioner  to ensure that the forms are completed correctly.

 

Is there an out of hours service or shift system?

During the out-of-hours period, two Biomedical Scientists (BMS) are on duty to respond to all haematology, blood transfusion and chemical pathology emergency requests for the hospitals in the district. Urgent, out-of-hours samples should be sent to the laboratory in Red Bags and will be processed in the same manner as urgent samples in normal working hours, i.e., within 1 hour of receipt. If requests are required more urgently, the Haematology  BMS should be contacted by bleep (3090)  or activate the Massive Haemorrhage Alert (3090) in cases of major trauma and haemorrhage.

 

Instructions for transportation of samples, including any special handling needs:

Routine samples can be transported via the pneumatic chute (222) or taken to Pathology reception level 5. In a massive haemorrhage situation a dedicated runner should transport  urgent samples directly to the  Transfusion laboratory to reduce  possible delays in providing suitable blood components

 

Information on those key factors which are known to affect the performance of the test or the interpretation of the results:

Adult samples must be greater than 2 ml in volume  and must not be stored for more than 24hours at room temperature.
