Strategies for Producing Protective Identities

Identification Category of LeachableProtective Identification Strategy
Leachables with a confirmed IDSafety assess the reported identity
Leachables with a confident IDSafety assess the reported identity
Leachables with a proposed but unconfirmed IDReport the primary (best match) identity and safety assess this candidate. Report other viable candidates and consider the candidate with the greatest risk of being toxic in the safety assessment.
Leachables with a partial identitySafety assess the compound that fits the reported compound’s class and which has the greatest risk of being toxic
UnidentifiedNo protective strategy is appropriate, although it may be useful to establish that the compound is not a compound with exceptionally high toxicity (cohort of concern)
