Dr. Joseph Litten has been an early adopter of Six Sigma metrics, using it to benchmark vendors as early as 2008, long before the Sigma Verification program existed. Dr. Litten also provided a chapter detailing his experiences in the latest edition of Clinics in Laboratory Medicine that we helmed.

The verification was completed on three ARCHITECT chemistry instruments and three immunoassay instruments. The analytes verified include
