Page History

This is an example showing the report table, trial design, and results from the in vitro bacterial reverse mutation test of an example study, Study #8325064. This bacterial reverse mutation test uses four different amino acid-requiring strains of Salmonella typhimurium (S. typhimurium) and one strain of Escherichia coli (E. coli) to detect point mutations, which involve substitution, addition or deletion of one or a few DNA base pairs.

A simplified image of the test procedure is shown above.

In this example, the Trial Summary dataset, ts.xpt, includes many informational fields that may provide context at the study level, for Study 8325064. Also, TSGRPID has been used to link records (name, location, country) related to the test facility (TSGRPID = 1) and records related to the Test Site (TSGRPID = 2). The Study Director is associated with the Test Facility and the Principal Investigator is associated with the Test Site. Finally, the Primary Treatment CAS Registry Number is not known and this is recorded as an empty TSVAL and UNKNOWN in the corresponding TSVALNF.

Rowcaps

Rows 1-22:	Show trial set parameters and trial set values that comprise the test conditions for the set SetA. SetA is the data for the vehicle control (i.e., Strain of TA98, vehicle control with concentration value of 0). SetA is associated with the first row, labeled "SetA", in the report table for example study 8325064.
Rows 23-44:	Show trial set parameters and trial set values that comprise the test conditions for the set SetR. SetR is the data for the vehicle control (i.e., Strain of TA100, positive control with a concentration value of 2). SetR is associated with the eighteenth row, labeled "SetR", in the report table for example study 8325064.

Observational Unit Identifiers (OBUIDs) are defined by the sponsor to uniquely identify the observational unit within an experimental unit. In this example the sponsor chose to define the EUIDs based on trial sets (e.g., F) and OBUIDs based on the position of the tube in one of multiple exposure/incubation plates (e.g, 6_1 for plate 6, position 1).
