Immunology
Specimens
2 liquid human serum or plasma samples, 0.5 mL
Examinations
Phospholipid antibodies, Cardiolipin antibodies (IgG and IgM), beta-2-glycoprotein antibodies (IgG and IgM)
Important Notes
Quantitative results are also processed.
Others
Specimens
2 liquid samples.
Examinations
100 - 1000 µL of the liquid samples shall be weighed by the participant, the result is reported in mg with a precision of two decimal places.
Important Notes
Up to 5 single-channel pipettes can be controlled. A calibrated laboratory scale with 0.01 mg resolution is required. This EQA scheme does not replace standardized pipette calibration, it does not fulfill the accreditation requirements for pipette calibration.
Pathology
Specimens
3-5 cases with preanalytical and process error(s).
Examinations
Participants are asked to find preanalytical or laboratory process error(s) in the cases.
Important Notes
The scheme is intended for all laboratory staff of pathology laboratories. Scheme is carried out online.
Preanalytics
Specimens
3 cases with preanalytical error(s).
Examinations
Participants are asked to find preanalytical error(s) in the cases.
Important Notes
The scheme is intended for personnel using POCT tests and devices. Scheme is carried out online.
Preanalytics
Specimens
3 cases with preanalytical error(s).
Examinations
Participants are asked to find preanalytical error(s) in the cases.
Important Notes
The scheme is intended for all laboratory staff of clinical microbiology laboratories. Scheme is carried out online.
Preanalytics
Specimens
Two surrogate blood vials (i.e. measurement devices for recording 3-axis acceleration during pneumatic tube system transport (PTS).
Examinations
Vials are sent through the PTS as regular blood samples, no laboratory analysis is performed. Rejection probability of LDH, ASAT and K will be calculated using the cumulative vibration level, laboratory defined analyte-specific hemolysis cutoffs, and a hemolysis model.
Important Notes
Vials are sent to the participating laboratories during September-October. Laboratories are asked to perform the recordings within one week upon receiving the vials and to return the vials using a courier (shipping costs not included). It is possible to measure 3 different lines from the same PTS manufacturer.

Clinical Chemistry
Specimens
2 human serum-based lyophilised samples.
Examinations
Procalcitonin.
Important Notes
