Pathway from presumptive TB to diagnosis, notification and treatment. This figure shows the section of the overall model after presumptive TB is identified. People identified with presumptive TB may be referred from a remote service to a central health facility for diagnosis. Access to TB diagnostic services can be improved by activities such as those depicted in red. The figure also shows that people identified with presumptive TB (positive screen) who do not have active TB (false-positive screen) will go through unnecessary diagnostic testing. A person diagnosed with active TB should be notified and started on treatment
