Dear Mr. Allbright:
The performance evaluation (PE) results submitted by your laboratory from the ERA Proficiency Testing Study
DMRQA-24 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.
