Uncertainty of Measurement and Traceability Webinar Slides and FAQs

As our accredited laboratories may know, AIHA Laboratory Accreditation Programs, LLC has undertaken significant efforts to develop, disseminate, and implement information on Uncertainty of Measurement and Traceability of Measurement since October 2009. This effort began with a notice to our site assessors citing the interim policy regarding traceability and the need to address (including citing deficiencies) during site assessments, and succeeded by the following in 2010:

• New Policies and guidance on both Uncertainty and Traceability were issued
• Internal training for site assessors and technical advisory panel members was conducted
• Two webinars conducted Spring 2010
• Training was offered at the AIHce Accredited Laboratory Forum

For those unable to participate in the training events above and/or to provide additional clarification, we have posted the  webinar slides and a list of  Frequently Asked Questions here.

We encourage accredited laboratories to use these tools, as AIHA-LAP requires site assessors to assess to our new Policies with focus on these two areas. Ad hoc reviews will continue throughout the year and into the future in an effort to ensure that all our participant laboratories, as well as the enterprise as a whole, has an excellent grasp on Uncertainty and Traceability.
