PURPOSE OF PROGRAMME:
To assess performance in undertaking standard patient pretransfusion serological testing, and decision making with respect to selection of red cells for crossmatch or issue. Other pretransfusion testing procedures are sometimes assessed on an educational basis.
|crossmatching and red cell phenotyping.|
MATERIAL PROVIDED: Whole blood, red cells in Alsever's, and plasma.
DISTRIBUTIONS PER YEAR: 4 distributions for all analytes ('R' coded exercises) and a further 6 for antibody screening and identification only ('E' coded exercises); the latter is optional for non-UK participants.
SAMPLES PER DISTRIBUTION: 9 samples representing 3 patients and 3 donors for 'R' coded exercises; 4 plasma samples representin
FREQUENCY OF DISTRIBUTION: One per month, except for August and December, as detailed in the annual schedule.
PROGRAMME OF ANALYSIS:
Results are entered online via the UK NEQAS Haematology and Transfusion website. 'E' coded exercises are live for 10 days and 'R' coded exercises for 2 weeks. Late results are only accepted if testing has been undertaken by the closing date and can be submitted on a form (which can be downloaded from the web result page) and emailed or faxed to the scheme.
Data is categorical and the target value is the 'true' value as determined by the Supplier (NHSBT Reagents Unit) and the UK NEQAS laboratory.
Each test is assessed and scored separately, with penalty scores weighted for potential clinical significance. A score below 80 is considered as satisfactory, 80 is borderline and 100 is unsatisfactory. A non or late return attracts 50 points.
Participant performance is monitored separately for each test over a 3 exercise rolling window.
PERSISTENT POOR PERFORMANCE:
This is defined as more than one episode of unsatisfactory performance within a 12 month period, for any combination of tests, including non or late return.
Blood Transfusion Laboratory Practice
UK NEQAS for Blood Transfusion Laboratory Practice (BTLP) is the expert centre within the UK National External Quality Assessment Service (UK NEQAS) for all aspects of EQA relating to blood transfusion pre-transfusion and diagnostic testing, with around 300 UK and 700 international registrations and a further 2000 individual members in our web-based training and competency assessment tool (TACT). UK NEQAS (BTLP) provides EQA services for pre-transfusion testing, feto-maternal haemorrhage and ABO titration, with pilot schemes in progress for direct antiglobulin testing and red cell genotyping.
