Blood Gas Analyzers and Point-of-Care Testing
When there is a question about the validity of a test result, the best rule of thumb is
Assume the values are true because today's POCT machines are highly accurate.
Recalibrate the POCT machine in question.
Draw two samples, reanalyze one on the POCT, and send one to the central lab for comparison.
Check to make sure the calibration reagents are not out of date.
None of the above.
