- •
A multi-laboratory validation for VFAs measurement is described.
- •
Acceptance criteria for performance parameters were suggested.
- •
Instrument precision should be lower than 1.5% RSD.
- •
Calibration linearity should be assessed using RSDSENSITIVITY and %RE.
- •
Appropriate VFAs measurements: precision (RSD ≤ 1.5%) and recovery (97–103%).
