Off-Schedule PT
Off-schedule proficiency testing (PT) provides laboratories with immediate, on-demand, customized proficiency testing for reinstatement or remedial purposes; a complement to the regularly scheduled PT program.
Who Needs Off-Schedule Testing?
Laboratories with unsuccessful performance (score of less than 80%) for two out of three regular testing events may be required to perform off-schedule PT to lift a “cease-testing” order from their regulatory or accrediting agency. In these cases, two acceptable proficiency performances (score of 80% or better) may be required for the lab to resume testing patients.
This service is available to every laboratory, regardless of MLE enrollment status.
