Sigma Metric Analysis
A recent study assessed the performance of a new hematology analyzer, the Landwind LW D3600.
What happens when you measure quality of a small wet chemistry veterinary analyzer using not only QC, but also pooled samples of canines and felines? Is this analyzer safe for any species?
At a recent veterinary laboratory conference, we had the chance to review some instrument evaluations. As it happens, these evaluations are based on QC and EQA data which applies to test performance relevant to human testing as well as veterinary testing.
IFCC EFLM have recommended that HbA1c methods be assessed using Sigma-metrics. We're starting to see papers now that incorporate Sigma-metrics into the instrument assessment. What are they telling us about today's latest HbA1c instruments? Are they good enough for use with patients?
At the end of December 2016, the Turkish Clinical Biochemistry journal published a study looking at the month to month Sigma-metrics of an AU 5800. Are Sigma-metrics changing month to month on this analyzer? What does that mean for QC?
