Laboratory Analysis Dataset (ADLB)

This is an example of an ADLB dataset and is based on input from the SDTM LB dataset. Other administrative data about the subjects are based on the ADSL dataset provided in Section 3.3.6.1, Subject-level Analysis Dataset (ADSL).

Example

This is an example SDTM datasets used to create the ADLB dataset. Only variables needed for illustration are shown in the examples.
