manual methods. Below is a list of all investigations provided by

CDDFT Transfusion Service
The CDDFT Blood Transfusion Laboratories, located at UHND &
DMH, provide a blood transfusion service to all of the trusts main
hospitals, community hospitals, hospices and GPs. The Transfusion
Department is both MHRA compliant and has been accredited
to UKAS ISO 15189:2012 (UKAS accredited testing
laboratory No. 8770). The transfusion laboratory participates in
all relevant external quality assurance schemes.
The Blood Transfusion Department test repertoire includes blood
group and antibody screening (with associated antibody
identification), compatibility testing (serological and electronic
issue), phenotyping, antenatal serology, kleihauer testing and
Direct Antiglobulin Test. The Blood Transfusion Laboratories
provide the following services:
Blood Grouping and Antibody Screening -
Routinely available on any patient if clinically indicated. For
non-medical reasons e.g. travel, sport, insurance or employment,
please contact the laboratory for arrangement under Category II
Antenatal Serology - A full antenatal serology
service is available.
Routine Crossmatch - Ideally 24 hrs notice
should be given for a non-urgent cross-match. This is to allow
sufficient time to investigate any abnormality detected in the
antibody screen or cross-match. If 24 hrs notice is not given, it
may not be possible to have blood available at the requested time
if an abnormality is detected in the course of the investigations.
This may result in the last minute cancellation of an elective
Emergency Crossmatch - The laboratory must be
informed by telephone. In an emergency, crossmatched blood can
normally be provided within one hour of receipt of the sample. In
exceptional circumstances, un-crossmatched O Negative (Flying
Squad) blood may be used. This can be taken directly from the Blood
Bank fridges located at DMH, UHND & BAH. If the Flying Squad
blood is used, the laboratory must be informed immediately so that
the blood can be replaced and a retrospective cross-match
performed. The trust operates a Major Haemorrhage Protocol which
all clinical staff should be aware and familiar with. Please refer
to POL/Transfusion/0003 Major Haemorrhage Policy for full details
(access via Staffnet 'Policies and Procedures' section).
Issue of Blood Products - A stock of fresh
frozen plasma and cryoprecipitate is kept at UHND and DMH blood
banks and is available on request (thawing time 30 minutes).
Platelet concentrates are not routinely stored on site and have to
be transported from the Blood Transfusion Services in Newcastle on
De-reserving of Blood - All blood will be
de-reserved and removed from the Blood Bank fridge 48 hours after
the time it was required. If blood needs to be reserved for a
longer period of time, this must specifically be requested.
Issue of Batch Products - A stock of albumin,
prophylactic Anti-D, Beriplex and Novoseven is kept at UHND and DMH
and is available on request. Please refer to appropriate
transfusion clinical policy for further details, accessed via
Staffnet 'Policies and Procedures' section.
