Laboratory Reporting

Laboratory Responsibility for Reporting of Tuberculosis in California

What must be reported?

Microscopic, culture, immunologic, serologic, or other evidence suggestive of tuberculosis.

This includes but is not limited to:
  • All smears positive for AFB
  • A positive nucleic acid amplification test (NAAT) for Mtb
  • Identification of mycobacterial growth upon culture media or broth
  • Identification of mycobacterial growth as Mycobacterium tuberculosis complex, Mycobacterium tuberculosis, Mycobacterium bovis, M. africanum, M. canettii, M. microti
  • Histologic evidence consistent with tuberculosis
  • Drug susceptibility test results on cultures positive for Mycobacterium tuberculosis complex
To whom should reports be submitted?
  • Results should be submitted to the local health officer in the jurisdiction where the health care provider who first submitted the specimen is located
  • Reference laboratories are responsible for notifying BOTH the laboratory that forwarded the specimen for isolate testing AND the local health officer in the jurisdiction where the health care provider who submitted the specimen is located
  • Submit one positive culture for TB to the local public health laboratory
When should these results be reported to TB Control? Within one working day from the time the health care provider or referring laboratory is notified of results
What information is required on the report?
  • Patient's name, identification number
  • Patient's age/date of birth, gender
  • Patient's address
  • Patient's telephone number (if known)
  • Provider's name, address, and telephone number
  • Date of specimen collection
  • Specimen accession number
  • Test performed and result
  • Date positive results were identified

The lab that first receives a specimen is responsible for obtaining the above information, and labs must forward this same information when transferring specimens between labs.

How is TB Control notified?

Written notification is required within one working day regardless of method of reporting.

Laboratories may elect to use the Confidential Laboratory Report form to report to the TB Control Program.
