What is quantiferon tb gold plus?
The QuantiFERON-TB Gold Plus (QFT-Plus) test measures plasma IFN-gamma levels to evaluate the cell-mediated immune response to two antigens from the Mycobacterium tuberculosis complex, ESAT-6, and CFP-10. If the test results are positive, you most likely were exposed to tuberculosis and have a latent infection (LTBI). To be sure you don't have TB disease in your lungs, you should get a chest X-ray.
A quick blood test called QuantiFERON-TB Gold (QFT) helps
identify the tuberculosis-causing bacteria, Mycobacterium tuberculosis (TB).
The QFT, also known as an IGRA (interferon-gamma release assay), is a more
recent alternative to the tuberculin skin test (TST, PPD, or Mantoux).
It is not advised to test healthcare workers for TB annually unless there is a known exposure or active transmission occurring at the facility. An annual TB symptom assessment for healthcare workers with untreated latent TB infection is recommended.
When is a quantiferon tb gold plus performed?
The most used interferon-gamma release test (IGRA) for detecting latent tuberculosis illness is QuantiFERON-TB Gold Plus (QFT-Plus) (LTBI).
What does quantiferon tb gold plus detect?
The tuberculosis-causing bacteria Mycobacterium tuberculosis (MTB) can be found with a fast blood test called QuantiFERON-TB Gold Plus (QFT-Plus) (TB). The less difficult, more affordable way of testing for TB infection produces more trustworthy results than the century-old tuberculin skin test (TST).
Laboratory-based TB interferon-gamma release tests (IGRAs) have revolutionized screening programs over the past 15 years with increased accuracy, practical benefits, and enhanced convenience. Over 1500 clinical and academic investigations have focused on QuantiFERON technology.
An Indirect Diagnostic Test
An indirect diagnostic test for both current and latent tuberculosis (TB) infection is QuantiFERON-TB Gold (QFT). To diagnose active TB disease that was not bacteriologically proven at the time of medication beginning, this study aimed to assess and compare the QFT and the tuberculin skin test (TST).
With electronic reporting, quantifiable data, and high accuracy, QFT-Plus uses an IGRA to measure the T cell immunological response to MTB and offers the ease of a single patient visit.
What are the benefits of the quantiferon tb gold plus test?
A quick blood test called QuantiFERON-TB Gold Plus
(QFT-Plus) helps identify the tuberculosis-causing bacteria Mycobacterium
tuberculosis (MTB) (TB). Compared to the century-old tuberculin skin test, it
is the less complicated, more economical method of testing for TB infection
that yields more reliable findings (TST). Negative findings imply that TB
infection is not present. A negative test should be repeated in patients who
have a strong suspicion of exposure. A positive test result in Mycobacterium
tuberculosis infection.
- Repeat testing has a little positive impact on later
immunological reactions.
- A previous BCG (Bacille Calmette-Guérin) vaccine does not
result in an IGRA test result that is falsely positive.
- Results are not affected by reader prejudice
When should I know the results of quantiferon tb gold plus?
Normally, the results are made public in three to five business days. All situations that would typically require a TB skin test can use the results. The BCG vaccine won't result in false positives in a Quantiferon TB Gold test, in contrast to a TB skin test.
Quantiferon tb gold plus Test Results range
A Quantiferon Gold test is deemed successful if the outcome
is less than 0.35 IU/mL. However, if tests somewhat above or below this
threshold are replicated, longitudinal studies have revealed that a
considerable proportion of test deprecations and conversions take place.
