On-site personnel that conduct environmental or product testing shall participate in an applicable proficiency testing program at least annually to ensure accuracy of results.
We do not conduct pathogen testing at our facility. We only conduct APC and YM for finished products and APC, YM, and EB for environmental zone 1 swabs.
Would we need to participate in an expensive accredited proficiency testing program for these tests? Would we be able to make our own proficiency test with our external accredited lab where we test the same sample as the lab and compare results?
Thank you for your help!
