Participant Centers for Disease Control and Prevention (CDC) Mycobacterium tuberculosis Nucleic Acid Amplification Testing

Enclosed are analyses of laboratory test results reported to the Centers for Disease Control and Prevention (CDC) by participant laboratories for the January 2002 shipment of samples for the CDC M. tuberculosis Nucleic Acid Amplification (M.tb NAA) Testing Performance Evaluation Program. Participant laboratories received five individual samples. Testing results were received from 80 of 84 (95%) enrolled laboratories that received this shipment. The enclosed aggregate report is prepared in a format that will allow laboratories to compare their results with those obtained by other participants for the same sample using the same M.tb NAA test method. We encourage you to circulate this report to all personnel involved with M.tb NAA testing, interpreting, or reporting. If you have any comments or suggestions on the format selected for the results, or questions regarding this report, you may call Laurina Williams at (770) 488-8130. Sincerely yours
