The performance evaluation (PE) results submitted by your laboratory from the AbsoluteGrade PT Program WP0019
DMRQA have been received and evaluated. The results detailed below represent the status for each of your certified
parameters and methods to date. A blank in the "PE complete" column indicates no PE yet recorded for this calendar year. A
"Pass" entry indicates your lab has satisfied the annual performance evaluation requirement for that parameter and/or method.
Other information in this column indicates vendor and Study identification. A "Fail" entry requires a follow up sample to be
analyzed and reported to this office within 60 days. An N/A entry represents parameter exemption from the performance
evaluation requirement. A date entered beside the "Fail" entry represents the completion deadline for this PE follow up.
