QuantiFERON-TB Gold Plus Testing and COVID-19 Vaccination

Canadian Healthcare providers offering QuantiFERON-TB Gold Plus Testing services.

QuantiFERON-TB Gold Plus (TBQ) is an immune-based test for tuberculosis infection. The accuracy of TBQ is predicated on the production of interferon gamma from a normal functioning, sensitized immune cell when exposed to TB antigens. The use of some vaccines is known to stimulate immune responses in a manner that could interfere with TBQ testing accuracy. The purpose of this Partner Update is to provide information regarding the COVID-19 vaccine’s potential impact to TBQ test performance and planning to mitigate any potential risk.
