Developing a Tuberculosis Genotyping Program
Developing a Written Plan
TB Programs should develop a written plan to describe activities,
responsibilities, and procedures for their TB genotyping programs.
The New York City and the Maryland TB programs graciously agreed
to share copies of their genotyping plans with other TB controllers.
These plans are posted on the WebBoard at http://web-tb.forum.cdc.gov.
To help TB programs develop a plan, Table 5.1 lists important initial
steps that should be considered. Which steps are required and which
are recommended depend on the decision the TB program makes about
the initial scope of their genotyping program. How to make the decision
about the initial scope of the genotyping program and the steps
in Table 5.1 are discussed in the next section of this chapter.

program plan.
