A small local survey on specific proteins was recently conducted in Western
Australia.
The results for caruloplasmin on fresh serum samples show that the results
by the Beckman Immage were on average 33% higher than on the Dade Behring
BNII.
Subsequent investigation using lyophilised QC material only show about a 10%
difference.
It is my understanding that both are standardised against the IFCC
International Protein Standard CRM 470.
A similar survey conducted in 1996 with Beckman Array and BNA did not show
this difference.
Has this difference been reported before?
Any comments would be appreciated.
