CLINICAL APPLICATION:
Diagnosis of subarachnoid haemorrhage
PURPOSE OF PROGRAMME:
Immunochemistry EQA scheme
ANALYTES:
| Analyte | Default Unit |
|---|---|
| The programme surveys performance in assays for the identification of haem pigments and the quantitation of bilirubin and oxyhaemoglobin | Presence or absence of haem pigments and their identification. Quantitation of CSF bilirubin and oxyhaemoglobin absorbance. Interpretation of results using coded comments |
MATERIAL PROVIDED: Liquid format. Normal or pathological CSF will be distributed whenever sufficient volumes can be obtained. The majority of samples will, however, be of an artificial matrix developed for use in the programme
DISTRIBUTIONS PER YEAR: 6
SAMPLES PER DISTRIBUTION: 2

PROGRAMME OF ANALYSIS:
Data entry via the web for the submission of results. Data analysis is commenced 21 days after sample dispatch. Late returns are accepted and will contribute to the laboratory's cumulative performance statistics
DATA ANALYSIS:
Qualitative responses are assessed by MI scoring in relation to the designated response
PERFORMANCE SCORING:
MI scoring
PERFORMANCE MONITORING:
Laboratory performance is assessed over a running analytical window of 6 Distributions (12 months)
PERSISTENT POOR PERFORMANCE:
Defined as being in the Poor Performance category for two or more successive Distributions
