    Biography
      Dr. Marie-Claire Rowlinson received her undergraduate and doctoral degrees in Medical Microbiology in the U.K. and then completed a post-doctoral fellowship in Medical and Public Health Laboratory Microbiology at UCLA. Following the fellowship, Dr. Rowlinson worked with the Association of Public Health Laboratories (APHL) in their Global Health program, building laboratory capacity. Since 2012, she has been at the Florida Department of Health (FDOH), Bureau of Public Health Laboratories in Jacksonville as the Assistant Laboratory Director and CLIA Laboratory Director. At FDOH, Dr. Rowlinson works closely with the Tuberculosis (TB) Control program and oversees one of the busiest public health TB laboratories in the U.S. Additionally, Dr. Rowlinson holds an Adjunct Assistant Professor position in the Department of Medicine at UF in Gainesville, co-located with the Southeastern National TB Center, a CDC TB Center of Excellence. Dr. Rowlinson continues to be involved with APHL: at the national level, as the Chair of the Infectious Diseases Committee and Member of the TB Subcommittee; and at the international level, consulting with the Global Health program, most recently working with the Ukraine Ministry of Health on their HIV testing algorithm.

    Abstract

    DATE:  August 11, 2020

    TIME:   9:00am PDT

     

    The goal of TB elimination, less than 1 case per million people per year, can only be achieved through a concerted effort to detect and treat persons infected with TB, which includes those persons with latent TB infection (LTBI). Persons with LTBI have been exposed to TB and although they are not infectious, they are at risk of progressing to active TB disease. Therefore, laboratory tests that can detect persons with LTBI play an essential role. A common way to test for exposure to TB is with a TB skin test (TST). Alternatively, there are blood tests, Interferon Gamma Release Assays (IGRAs). Both methods rely on detecting a person’s immune response if they have been exposed to TB. However, there are some advantages to IGRA testing, particularly since this testing is performed in a controlled laboratory environment and elicits a more specific immune response. This presentation will discuss the pros and cons of performing IGRA testing as part of the TB testing program and the impact of recent changes in IGRA testing methodology.

     

    Learning Objectives:

    • Review the role of IGRAs in the diagnosis of TB infection
    • Summarize recent changes in IGRA testing including guidelines associated with testing certain populations
    • Discuss the implementation of IGRA testing in a public health testing program
