Overview Peer Review Panel

Peer Review Panel Meeting

NICEATM and ICCVAM convened an independent scientific peer review panel meeting on April 28-29, 2009, to evaluate three non-radioactive modified versions and new applications for the Murine Local Lymph Node Assay. The Panel peer reviewed the draft review documents for each topic and evaluated the extent that established validation and acceptance criteria have been appropriately addressed. The Panel also commented on the extent that the review documents support draft ICCVAM recommendations on proposed test method protocols and uses. The Panel's conclusions and recommendations will be published in the Panel's report, which will be available on this page in June.
