PT Summary Reports
PT Summary reports from January 2024 to present can be found on each individual test group page. Older reports are available on request.
These reports are to be used in conjunction with the confidential PDF report emailed to each participant. It identifies the scoring system used and the overall performance summary for all participants. Each report provides an overall summary of performance, by individual analyte, for all participants. These include:
- Summary statistics;
- z-score plots;
- Kernel density plots;
- Stability and homogeneity plots;
- Box-and-whisker plots; and
- Comparison plot of current PT round to historic rounds.

General notes
PT results must be reported in the units indicated, using the PTC Portal by midnight of the study deadline. Results will not be accepted after the deadline and an evaluation will not be provided. Provide information on results, date analyzed, and confirm that method is correct. PT samples must be treated with the same level of effort and workflow as the majority of client samples. Collusion or falsification of PT study data will result in withdrawal of PT recognition.
