We use BioRad MultiQual Level 1 diuted 1 in 20 with deionised water for IQC. The QC lot currently in use gives a value of 0.024 for NOA and 0.013 for NBA.

We are preparing for an upcoming UKAS inspection and I would be interested to know how other laboratories have made an assessment of measurement uncertainty for CSF xanthochromia analysis?
Also, does anyone use CSF Xanthochromia IQC?
Any information is much appreciated!
