The Sample Exchange Registry is an Internet-based service designed to connect laboratories performing testing where no formal proficiency testing (PT) is available. Laboratories can participate in the registry service at any time.
When at least three laboratories are identified as testing for the same analyte, the CAP will facilitate the sample exchange. The laboratories will test the samples and send their results to the CAP. The data will be made anonymous, and each individual laboratory will receive its own results along with an anonymous summary report of all the participants.
