Phospholipid Antibodies
ACCREDITATION STATUS:
UKAS accredited proficiency testing provider No. 7795
CLINICAL APPLICATION:
Diagnosis of autoimmune disease
PURPOSE OF PROGRAMME:
Autoimmunity EQA scheme
ANALYTES:
| Analyte | Default Unit |
|---|---|
| B2 Glycoprotein 1 (IgG/M) | Qualitative response or quantitative response in GPLU/ml or MPLU/ml for Phospholipid antibodies |
| Cardiolipin antibody (IgG/M) | Qualitative response or quantitative response in GPLU/ml or MPLU/ml for Phospholipid antibodies |
| Phosphatidylserine (IgG) | Qualitative response or quantitative response in GPLU/ml or MPLU/ml for Phospholipid antibodies |
MATERIAL PROVIDED: Liquid format. Normal and pathological human serum
DISTRIBUTIONS PER YEAR: 6
SAMPLES PER DISTRIBUTION: 2
FREQUENCY OF DISTRIBUTION: Every two months as outlined in the Distribution Schedule
PROGRAMME OF ANALYSIS:
Data entry is 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:
Laboratories are requested to give a qualitative interpretation of the cardiolipin, β2GP1 and phosphatidylserine antibody results. This element of the programme is assessed by MI scoring. Reports show the quantitative responses returned for each analyte in relation to both All Laboratory and Method / Manufacturers pecific data
PERFORMANCE SCORING:
MI scoring
PERFORMANCE MONITORING:
Laboratory performance is classified in terms of OMIS derived from the qualitative responses for all analytes for which the laboratory is registered during a time window encompassing 6 Distributions (12 months)
PERSISTENT POOR PERFORMANCE:
Defined as being in the Poor Performance category for two or more successive Distributions
