IID-32 Data Details

IID-32 Reduce the average time for laboratories to confirm and report tuberculosis cases

About the Data

Description of the data source, numerator, denominator, survey questions, and other relevant details about the national estimate.

National Data Source
National TB Surveillance System (NTBSS); Centers for Disease Control and Prevention, National Center for HIV/AIDS, Viral Hepatitis, STD, and TB Prevention (CDC/NCHHSTP)
Changed Since the Healthy People 2020 Launch
Baseline (Year)
32.0 (2008)
Target-Setting Method
Maintain consistency with national programs, regulations, policies, and laws.
Number of patients with a positive NAAT result within 2 days of specimen collection
Number of all the culture confirmed cases of tuberculosis
Comparable Healthy People 2010 Objective
Adapted from HP2010 objective
Methodology Notes

Nucleic acid amplification tests are capable of detecting Mycobacterium tuberculosis in a specimen within 48 hours of collection. Concerns regarding sensitivity, cost, quality control, availability and special expertise requirements have hindered widespread use of such tests. Upgrading TB laboratory capabilities and facilities, improving training in state-of-the-art mycobacteriology, and evaluating proficiency should better enable laboratories to apply these rapid tests to the diagnosis of TB.

Revision History

Any change to the objective text, baseline, target, target-setting method or data source since the Healthy People 2020 launch.

Description of Changes Since the Healthy People 2020 Launch

The objective statement was revised from "Reduce the average time for laboratories to confirm and report tuberculosis cases" to "Increase the proportion of culture confirmed TB patients with a positive nucleic acid amplification test (NAAT) result reported within 2 days of specimen collection" in order to make the objective statement consistent with the desired direction and value label.
