Latent Tuberculosis Infection Reporting Requirements and Updates to NAC441A


On Dec. 10, 2023, the Nevada Legislative Commission approved amendments to Nevada Administrative Code (NAC) 441A that included new reporting requirements for the condition Latent Tuberculosis Infection (LTBI). Amendments were made to align LTBI reporting with the Centers for Disease Control and Prevention (CDC)1 and Healthy People 20302 goals to reduce tuberculosis disease through expansion of testing and treatment for LTBI. Official codification of NAC 441A.350 LTBI amendment is pending, however the approved amendments can be found here.

This technical bulletin provides guidance to health care providers for LTBI required reporting elements and methods to ensure proper reporting to the health authority.

Reporting Requirements for LTBI

Amended NAC 441A.350 subsection 2 requires that, “A health care provider shall report to the health authority within 5 days after the discovery of any case having latent tuberculosis.” LTBI diagnosis is verified when the following are met:

  1. A positive Mantoux tuberculin skin test or interferon gamma release assay test;
  2. No radiological evidence of active tuberculosis in the lungs;
  3. No signs or symptoms consistent with tuberculosis disease; and
  4. No documented prior tuberculosis infection.

The following elements of LTBI diagnosis must be reported to the health authority:

  • Patient and provider information as required in NAC 441A.230 which is found here.
    • TB test results: Must include the result of test, date of test, and test type (skin or blood, like a QuantiFERON or TSPOT).
    • Chest radiograph: Must include the date performed and result of radiograph.
    • Physical examination: Must include date of exam and result of exam.
    • Immunocompromising conditions or planned immunosuppression identified (if applicable).
