This is an example CRF used to collect routine safety laboratory tests from local laboratories in tobacco studies. The lab names may be collected only when multiple labs are used by a site. The lab test name are often preprinted on the CRF. The names are not included as they are study specific. In order to save space, some of the permissible values are only shown in the metadata specifications.
