Oxford Immunotec Welcomes Updated CDC Recommendations for Tuberculosis Screening and Testing of Healthcare Personnel
OXFORD, United Kingdom and MARLBOROUGH, Mass., May 17, 2019 (GLOBE NEWSWIRE) -- Oxford Immunotec Global PLC (Nasdaq:OXFD) (the "Company"), a global, high-growth diagnostics company, today announced that it welcomes the updated Tuberculosis Screening, Testing, and Treatment of U.S. Health Care Personnel: Recommendations from the National Tuberculosis Controllers Association and CDC, 2019, published by the U.S. Centers for Disease Control and Prevention (CDC)1. These guidelines increase the focus on eradicating tuberculosis (TB) disease in the United States through an individual risk-based approach to screening and treatment for Healthcare Personnel (HCP).
Key highlights from the updated guidelines include:
- Recommendation for TB Screening and Individual Based TB Risk Assessment on Hire: continue baseline screening of all HCPs upon hire with the addition of an individual risk assessment
- Recommendation to Focus Serial Testing on Higher Risk Individuals: decision to perform TB testing after baseline based on HCP’s risk for TB exposure at work or elsewhere
- Recommendation for Latent Tuberculosis Infection (LTBI) Treatment: treatment, including short-course therapy, is now strongly recommended for all HCPs diagnosed with LTBI
“We are pleased to see increased focus on preventative screening and treatment for LTBI,” said Dr. Peter Wrighton-Smith, CEO of Oxford Immunotec. “These updated recommendations underscore the need to treat LTBI in order to eradicate active TB. We expect these guidelines to further the trend toward IGRA adoption for healthcare personnel screening due to high test accuracy and reduced number of patient visits.”
There are currently two types of tests available for TB screening in the US, the tuberculin skin test (TST) and interferon gamma release assays (IGRAs). The 2017 TB diagnostic guidelines of the American Thoracic Society, Infectious Diseases Society of America and CDC recommend performing an IGRA instead of a TST for patients who are unlikely to be infected with TB, such as most HCPs.2
The performance of Oxford Immunotec’s IGRA, the T-SPOT®.TB test, specifically in HCP testing is well documented in the largest published study of US HCPs, with over 42,000 T-SPOT.TB tests across 19 geographically diverse hospitals.3 The results of this study demonstrated that the T-SPOT.TB test provided consistently reliable results in both high and low risk real world HCP settings.
About the T-SPOT.TB test
The T-SPOT.TB test is a single-visit blood test for TB screening and is one of only two recommended alternatives to the TB skin test. The T-SPOT.TB test has demonstrated both sensitivity and specificity exceeding 95% and reliability in challenging patient populations, including immunosuppression, in its’ pivotal clinical study. The test does not cross react with the BCG vaccine and there is no association between T-SPOT.TB test results and immunocompromised status.4
T-SPOT.TB is available nationally through Quest Diagnostics and regionally through laboratory partners.
