Public Health Reporting for Laboratories

Licensed laboratories shall report:  

  • all test results indicative of and specific for the diseases, infections, microorganisms, and conditions specified above. Such tests include but are not limited to: microbiological culture, isolation, or identification; assays for specific antibodies; and identification of specific antigens, toxins, or nucleic acid sequences.
  • within seven days, the results of all tests of CD4+ T-lymphocyte absolute counts and the percent of total lymphocytes that are CD4 positive, and HIV nucleic acid (viral load) tests.

Laboratories identifying possible agents of bioterrorism should contact Public Health and refer the isolates to the Oregon State Public Health Laboratory immediately, day or night.
