An interesting article
with cross-discipline aspects to be considered. This case illustrates
how very high immunoglobulin levels can ccause interferences in many
test results including
- the prozone effect
- the volume displacement effect
- precipitation interference.
We need to bear in mind
potential sources of discrepant results in patients with high plasma
protein concentrations and should take care to prevent the release of
erroneous results.
It's not all about just
churning out whatever number the analyser produces...
