RL0121 12 Posted April 22 Hello, I’m in the autoimmune sector and would like to found out from anyone who can share their Proficiency Testing Policy that includes providing evidence of compliance in reviewing Ungraded PT results . Since we perform specialized testing , we don’t have enough labs to compare our answers with. I’m updating our PT policy to address this requirement. I appreciate any assistance I can get. Thank you . Stay safe everyone 😷 Share this post Link to post Share on other sites
