- Determining the Need for Additional Testing With Quantiferon TB Gold in . . .
QuantiFERON-TB Gold (QFT) is an interferon-gamma release assay (IGRA) which, unlike the TB skin test, is not affected by prior BCG vaccination and is not expected to give a false-positive result in people who have received the BCG vaccine
- Bacille Calmette-Guérin (BCG) Vaccine for Tuberculosis
TB blood tests (interferon-gamma release assay or IGRA) are the preferred test for people who have received the BCG vaccine, including children BCG vaccination does not induce positive results when TB blood tests are used
- Predictors for a positive QuantiFERON-TB-Gold test in BCG . . . - PubMed
QuantiFERON-TB Gold assay (QFT-G) is more specific for infection with Mycobacterium tuberculosis than the TST, especially among persons vaccinated with bacillus Calmette-Guérin, thereby reducing the number of false positive tests
- QuantiFERON-TB Gold+ for the Diagnosis of Mycobacterium . . . - AAFP
QuantiFERON-TB Gold+ testing for the diagnosis of active or latent TB is easily interpreted and more specific than tuberculin skin testing in BCG-vaccinated populations In environments
- BCG Vaccine Impact on TB Testing - Health Street
In the USA, where PPD testing is a common diagnostic tool to determine if someone has active TB, a history of BCG vaccination may complicate matters 1 TB Testing the BCG Vaccine: What Every Employer Needs to Know 2 What is tuberculosis? 3 How does TB testing work? 4 What choices do employers have for TB screening?
- Predictors for a positive QuantiFERON-TB-Gold test in BCG-vaccinated . . .
We identify predictors for a positive QuantiFERON among TST+ BCG-vaccinated persons The strongest predictor was evidence of healed TB infection on a chest radiograph Another strong predictor was being from a country with a high incidence of TB QuantiFERON is preferred to the tuberculin skin test in BCG-vaccinated persons
- DETERMINING THE NEED FOR ADDITIONAL TESTING WITH QUANTIFERON TB GOLD IN . . .
The purpose of this study is to determine which patient characteristics in patients with positive TST and previous history of BCG vaccination are associated with positive QFT so that we can eliminate the need for additional QTB testing in this patient population
- Testing for Tuberculosis: Blood Test | Tuberculosis (TB) | CDC
TB blood tests are the preferred tests for people who have received the BCG TB vaccine You can get tested for TB at the health department or at your health care provider's office Your health care provider will choose the TB test that is best for you Public and private health care plans may cover TB testing costs
- Performance of QuantiFERON-TB Gold In-Tube test and Tuberculin Skin . . .
Quantiferon-TB Gold In Tube test (QFT-GIT) has been reported to have better sensitivity and specifity than TST In this study, it was aimed to compare the performance of a commercial IFN-γ release assay (QFT-GIT) with TST in the diagnosis of HCWs at risk for latent TB infection in BCG vaccinated population
- How should we manage a patient with a positive PPD and prior BCG . . .
A recently developed alternative is the interferon-gamma assay (QuantiFERON-TB Gold test), which may be used in place of, or in addition to, the PPD skin test for patients who are known to have received a BCG vaccine (SOR: B, extrapolation from a validation cohort study)
