  • High quality, homogeneous, stable testing samples that arrive ready to analyze, like routine samples
  • Confidential and secure PT website to enter data and access historical data and reports

PT On-Demand

Need PT results right away? Order at any time without waiting for the next scheduled round. Your laboratory receives test materials identical to those used in scheduled PT rounds, submits results through a secure and confidential reporting portal, and receives performance evaluation using the assigned values and standard deviations established from the corresponding scheduled round. This provides results comparable to traditional PT participation, with reports typically issued within 48 hours of result submission.

Quality Assurance and Educational Samples (QAES)

AOAC’s Proficiency Testing Quality Assurance and Educational Samples (QAES) program offers samples that are available for quality assurance and educational purposes and are separate and different from proficiency testing samples. These samples can be used for training, corrective actions, method development, examining method equivalence & performance, method validation, and more.
