1 2008 HFC-A PARTICIPANT SUMMARY Evaluation Criteria Analyte Target Value Evaluation Criteria Red Blood Cell Peer Group ± 3 SD White Blood Cell Peer Group ± 3 SD Cytopreparation Differential Educational In the event a result is not graded, a numeric code will appear next to your result. A definition of the code will appear on the first page of your evaluation. Please see Actions Laboratories Should Take when a PT Result is Not Graded on page 5. To provide a timely evaluation of your results, statistics presented in this Participant Summary reflect a minimum of 80% of participant enrollment. 1

2 2008 FH1-A PARTICIPANT SUMMARY Evaluation Criteria Analytes regulated for proficiency testing appear in bold type. Quantitative Analyte Target Value Evaluation Criteria Hematocrit Peer Group ± 6% Microhematocrit (waived) Peer Group ± 6% or 2SD (whichever is greater) Hemoglobin Peer Group ± 7% Lymphocytes* Peer Group ± 3 SD or ±1.0 (whichever is greater) MCV Peer Group ± 3 SD Neut/Gran* Peer Group ± 3 SD or ±1.0 (whichever is greater) Platelet Count Peer Group ± 25% RDW Peer Group ± 3 SD Red Blood Cell Count Peer Group ± 6% White Blood Cell Count Peer Group ± 15% Your results are evaluated based upon a range of acceptability. The range is determined using a target value and a limit. The target value is your peer group mean. There must be at least 10 laboratories in the peer group. Qualitative Analyte Blood Cell Identification * Evaluation Criteria 80% referee or participant consensus *Blood Cell Identification results are included in the CMS performance summary. In the event that Blood Cell Identification is not performed, results from the flow through differential will be reported. The CAP is required to submit PT results to the Centers of Medicare and Medicaid Services (CMS) for all labs that have provided a CLIA identification number. If you do not notify the CAP that your lab has discontinued testing of a regulated analyte, a score of zero will be given. Your reporting preferences are outlined on the CMS Analyte Reporting Selections document, which can be obtained by contacting the Customer Contact Center at , option 1. Additional information regarding this document and associated reporting requirements can also be found at To provide a timely evaluation of your results, statistics presented in this Participant Summary reflect a minimum of 80% participant enrollment. In the event a result is not graded, a numeric code will appear next to your result. A definition of the code will appear on the first page of your evaluation. Please see "Actions laboratories should take when a PT result is not graded" on page 24. 1

The CV is calculated as the standard deviation (SD) divided by the mean, multiplied by 100. When the mean value is very low, the CV may be exaggerated. 3
