    SFDPH currently recommends that patients suspected of having active TB have both a TST and a QFT. The QFT, like the TST, is a diagnostic aide for the detection of TB infection. Patients with active TB can be either TST negative, QFT negative, or both. Therefore when clinical suspicion of active TB is present, the results of both tests should be interpreted in the context of the clinical, microbiologic and radiographic examinations.

    Active Vs Latent Tuberculosis

    10. What is the Quantiferon Gold Test?

    IGRAs cannot distinguish between latent infection and active tuberculosis disease, and should not be used as a sole method for diagnosis of active TB, which is a microbiological diagnosis. A positive IGRA result may not necessarily indicate TB infection, but can also be caused by infection with non-tuberculous mycobacteria. A negative IGRA does not rule out active TB disease a number of studies have shown that up to a quarter of patients with active TB have negative IGRA results.

    Who Should Not Take The Quantiferon

    Besides children, there are certain population groups that are not considered viable candidates for taking this blood test. Anyone who has an altered immune function fits into this category. This may be the result of an autoimmune disorder, an HIV infection, or people who are receiving immunosuppresive medications.

    Certain clinical conditions may also alter the effectiveness of the results. This includes people who have a confirmed diagnosis of diabetes, renal failure, certain cancers and blood disorders, and silicosis.

    Women who are pregnant are also not considered good candidates for this blood test.

    The CDC, however, has approved the use of this blood test as a screening tool for virtually all individuals based on current data, even if the results from the test have not been studied. This is why it is important to speak with your provider about this specific blood test to see if it would be right for you.

    What Is A Quantiferon Tb Gold Test

    TB gold is also known as QuantiFERON TB gold. It is a simple blood test done to diagnose the presence of tuberculosis bacterium in the body. QuantiFERON is an Interferon Gamma Release Assay used to detect the TB bacterium. It measures the response of a persons immune system with the help of a certain substance called gamma interferon. This substance is released by the white blood cells in a blood sample when they are exposed to specific TB antigens.

    What Do The Results Mean

    The QuantiFERON-TB Gold blood test will come back with either a positive or a negative result. In some people, an inconclusive result may occasionally occur. A negative result means that there is not active or latent tuberculosis infection. A positive result is an indication that there is an infection that is present and that follow-up treatment may be necessary.

    An inconclusive test is generally cause by a laboratory error or a blood sample that has sat for too long.

    The one issue that may present itself for some people is that blood test results must be processed within 12 hours of collection in order for the test to be accurate. For medical providers that must ship out blood draws to a laboratory for this test, it may be impossible for the sample to reach the lab in time. In these instances, the TST is still the best choice.

    The QuantiFERON-TB Gold blood test may be a more accurate diagnostic tool, but it is not considered a complete replacement for a medical providers personal judgment. For those who have had repetitive TSTs in the past and need a definitive result, then this blood test may be able to provide it.

    What Is Tb Quantiferon Test

    TB Quantiferon is a special blood test used to detect the presence of Mycobacterium tuberculosis infection. It replaced the century-old TB skin test which is also known as PPD, Mantoux test, tuberculin skin test or TST.

    What is a TB Skin Test?

    Before, the only way of detecting Mycobacterium tuberculosis infection is to do a TB skin test. Its done by injecting a small amount of TB protein under the skin. If you have an active TB infection or if you have been exposed to Mycobacterium tuberculosis, a wide red bump will develop around the injection site.

    How does a TB test look like when it is positive?

    When a tuberculin skin test is positive, an induration or localized swelling will appear after 1-3 days. It has to measure more than 5mm in diameter to consider it positive.

    What are the advantages and disadvantages of a tuberculin skin test vs the Quantiferon-TB test?

    A tuberculin skin test is cheaper than the QuantiFeron-TB Gold Plus. However, it cannot differentiate active or latent infection and it takes three days to be read.

    The QuantiFeron-TB Gold Plus, on the other hand, can confirm active tuberculosis infection. It uses highly specific TB antigens that aid in properly detecting the presence of TB infection in the blood. It takes a maximum of 24 hours to get the results.

    Are Test Results Accurate

    TB blood tests are reliable and widely used. False positives, in which a person tests positive despite not having an infection, are uncommon in TB blood tests.

    TB blood tests do have limitations and can produce false negatives, in which a person has a negative test result despite having a TB infection. This can occur in individuals with immunosuppressive conditions, including: lHIV infection, known TB disease, or anergy, which is a lack of a typical immune response.

    The timing of the test can also affect the accuracy of results. If a person is tested too soon after their exposure to tuberculosis bacteria, they may have a false negative result. Experts recommend testing at least 6 to 8 weeks after the exposure to TB.

    How Does A Quantiferon Test Work

    QuantiFERON TB Gold u reumatologiji

    A QuantiFERON TB test is a simple blood draw. The blood is then tested in a laboratory to measure the strength of the bloods reaction to tuberculosis bacteria, thus determining whether a person has been infected with TB bacteria.

    Cases of positive TB test results require a follow-up chest x-ray for visual confirmation. The QuantiFERON blood test represents industry-standard testing for TB screening. However, false positives may occur. Consequently, the only way to confirm active tuberculosis in a patient is through a chest x-ray.

    Chest x-rays are available to all patients who have a positive PPD skin test or QuantiFERON test result at Mobile Health.
