Are Preanalytical errors still Predominant?
A recent study evaluated the frequency of preanalytical errors in a stat lab. In our continuing review of error rates, we begin to see evidence that dramatic improvements have been made in preanalytical processes, but significant gaps in analytical performance remain.
When we compare preanalytical and analytical errors on the Sigma scale, does any testing phase "win"?
Sigma-metric evaluation of four POC analyzers
A study published back in 2012 examined the performance of 4 different POC analyzers and one HbA1c analyzer. These devices were meant to support a network of anti-retroviral clinics in South Africa. The study sought to find an analyzer that could improve clinical efficiency and patient care in HIV infected patients by enabling faster decision making. With this in mind, we evaluate the analyzer performance on the Six Sigma scale.
What matters most? Making a fast decision? Or making the right decision?
Alkaline Phosphatase (ALP) Goals: Can any method hit the mark?
Continuing with our series examining quality requirements and goals and the performance of methods, we turn to alkaline phosphatase (ALP) methods. We examine the different goals offered and evaluate what current methods are capable of achieving.
Are the German Rilibak goals always the most generous?
