We recently noted discrepant results when we had measured CRP on two
separate specimens taken from the same patient within a couple of hours.
It appears that even slight amounts of haemolysis cause large
artefactual elevation of plasma CRP.
The assay we are using is the Diasys method distributed by Biostat in
the UK, running on an Abbott Aeroset analysers.
We are trying to sort this out, and would be grateful to know of others'
experiences, with this or other assay systems.
