translate English to French: Criteriabased public coverage for many genetic tests may ensure access and efficiency. Unnecessary use of tests will only be avoided, however, if denial of public coverage on reasoned and needs-based grounds sends a signal to patients that dissuades them from seeking the test through the private market—complementary costs of which would ultimately be borne by the public system.
La couverture publique fondée sur des critères peut assurer l’accès au dépistage et son efficacité.
