Quantiferon TB Gold Plus Assay

Written by: Solaris Diagnostics

Tuberculosis is a communicable disease caused by infection with M. tuberculosis complex organisms (M. tuberculosis, M. bovis, M. africanum, M. microti, M. canetti and M. caprae), which typically spreads to new hosts via airborne droplet nuclei from patients with pulmonary tuberculosis disease.

Solaris Diagnostics Laboratory offers Quantiferon TB Gold Plus (QTF-Plus) assay which uses specialized blood collection tubes, containing peptide antigens that simulate M. tuberculosis protein, which is used to collect whole blood. Incubation of the blood occurs in the tube for 16-24 hours, after which, plasma is harvested and tested for the presence of Interferon gamma produced in response to the peptide antigens.

The American College Health Association (ACHA) recommends screening all incoming students for tuberculosis risk factors and testing students at risk with a TB blood test.

A single one tube blood test is:

  • Accurate – does not cross-react with the BCG vaccine
  • Convenient – single visit testing with an available single-tube blood draw
  • Cost-effective – covered by insurance, with reduced x-ray and follow-up costs
