Westgard Sigma Analysis: Six Homocysteine methods

different methods for this important analyte. But in the absence of a CLIA
quality requirement, how can we compare performance?
Interview: Paul Epner, MEd, MBA and Labs are Vital (tm)
The recently-retired head of the Labs Are Vital™ initiative talks about
developing, launching, and growing the popular laboratory community

Guest Essay: Kathy Freeman, DVM, PhD et al on QC for Veterinary
Medicine
In a previous issue, we presented some of the findings and quality
requirements from a landmark paper by Kathy Freeman, DVM, PhD, and Alison Farr.
Freeman and Farr have graciously followed up with a guest essay discussing their
efforts to establish quality requirements for veterinary medicine tests and
calculate Sigma-metrics based on those results.
