Estimados amigos, una vez más molesto con un término que me trae dudas: screening.

Según el contexto, procedería la traducción del término como seguimiento/diagnóstico/control?

(...) CEPA required that the Ministers of Health and Environment complete categorization (priority setting) of all of the approximately 23,000 substances on the Domestic Substances List (DSL) by September 2006, with subsequent screening and full risk assessment, where warranted.

Full assessments for Priority Substances generally
include early peer input to identify relevant data,
followed by external panel peer reviews at the end of
the process. On the other hand, for screening assessments, an early issue identification stage is envisaged (...)

To increase the efficiency of assessment of larger
numbers of substances, it is envisaged that screening
health assessments for Existing Substances under
CEPA will incorporate an early, formal stage of
Issue Identification.

As a result, the program provides opportunity for incorporation of increasingly complex and robust models of peer involvement not only for assessments of individual substances or groups thereof (i.e., screening to Priority Substances) but also for development of complex predictive novel methodology (for categorization).
