Is it true that the lead test kits that were recognized by EPA before September 1, 2010, are no longer recognized since that date?
No. The test kits that were recognized by EPA before September 1, 2010 did not automatically lose their recognition on September 1, 2010. As discussed in the 2008 RRP rule, prior to September 1, 2010, manufacturers seeking recognition of their test kit had to meet only the false negative response criterion. EPA-recognition of test kits meeting this criterion will last until EPA publicizes its recognition of a kit that passes both the false negative and the false positive criteria.
