In vitro Micronucleus Assay

This is an example showing trial design and results data of Study #123 for the determination of the in vitro genotoxicity potential of 10 tobacco products in the in vitro Micronucleus Assay

red font - indicates potential for CT code lists
purple font - questions to resolve yet

Assumption: Study can have more than one assay type
Assumption: ASSAYID value of ALL means it applies to all assays in the study
BLEO & CPA - are positive controls, should this be included/where is this captured? — in results for the record / row?
Where is TK6 cell type? is this test system (see below)
