Key Highlights
QuantiFERON-TB Gold Plus (QFT-Plus) is a new blood test. It helps find out if you have an infection from Mycobacterium tuberculosis, the germs that cause TB.
- Unlike the old skin test, QFT-Plus does not react to the BCG vaccine. This makes it more accurate for people who have had the vaccine.
- This test is very useful for diagnosing latent tuberculosis infection (LTBI). LTBI is a quiet form of TB that may not show any symptoms, but it can turn active later.
- The test looks at how your blood reacts to TB antigens. It gives a clear picture of your TB status.
- QFT-Plus is usually safe, and you can get results in about 24 to 48 hours.
Top Pick: Quantiferon Gold for TB Testing
This has become the go-to test for TB. This technology is fast and accurate. If you need to be tested fast and accurate then this is the way to go. Quantiferon Gold tests are now available at Discounted Labs in many cities across the US. No need to go to a doctor’s office or clinic. In this post we will go over what is quantiferon gold, who should get tested with it, how it’s done, any risks, and where you can find discounted labs that offer this test so you know all your options before you get tested.
The QuantiFERON-TB Gold Plus (QFT-Plus), also known as an interferon gamma release assay (IGRA test), is a lab test. It uses a peptide cocktail that looks like the ESAT-6 and CFP-10 proteins to wake up cells in whole blood that have been heparinized. There is an ELISA that can find interferon gamma (IFN-g) and see how well T cells defend against Mycobacterium tuberculosis (MTB). It measures in vitro responses to these peptide antigens that are linked to M. tuberculosis infection so it’s an important tool in diagnosing and monitoring the immune response to TB. When you have an M. tuberculosis infection, CD4+ T cells are very important in blocking the infection because they release IFN-gamma. A test called QuantiFERON-TB Gold In-Tube (QFT-Gold) could only find IFN-gamma that was released by CD4+ T cells before the QFT-Plus test.
While the QuantiFERON-TB Gold Plus test is good at diagnosing TB infection, it doesn’t differentiate between active tuberculosis disease and latent tuberculosis infection and should be used with clinical evaluation.
What is Quantiferon Gold?
It’s an advanced version of the traditional TB skin test, which requires multiple visits and has been found to be less accurate than Quantiferon Gold. The Quantiferon Gold test also known as the QuantiFERON TB test can be done in one visit and is more accurate than the skin test. But the QuantiFERON TB test has its own limitations, especially in diagnosing tuberculosis infection in immunocompromised individuals where results can sometimes be indeterminate. It’s also sometimes called the IGRA test or med. Guidelines recommend doing both IGRA and tuberculin skin tests in immunocompromised patients to detect latent infections and treat if either test is positive.
Interferon Gamma Release Assays Overview:
When white blood cells touch TB bacteria, they release interferon-gamma. Antigens are used in the test to measure the immune response, particularly through specialized blood collection tubes designed for this purpose. The Quantiferon Gold test measures the amount of this protein in 1.0 ml of blood from the patient’s arm. If high levels are detected, it means the person has been exposed to or infected with TB bacteria and is at higher risk. The whole process takes about 2 hours and results are available within 24 hours after testing. The QFT result is indeterminate, meaning it can be inconclusive. What do we tell the patient and what do we do? A high background level of interferon-gamma (a negative control that doesn’t work) or no response to the mitogen (a positive control that doesn’t work) can result in an indeterminate result. Repeat QFT or TST placement depends on patient and provider preference. In San Francisco, repeating the QFT will result in a valid result 65-75% of the time. If the result is nil or negative, it must be within the recommended range of ≤8.0 IU/mL to be considered valid.
Advantages:
The main advantage of using Quantiferon Gold over other tests for TB infection, such as the TB skin test or chest X-rays, is its accuracy and convenience. The QuantiFERON Gold test is a TB blood test that detects the immune response to TB bacteria in individuals who may have been exposed to or are at higher risk for TB. These tests can give false positives due to environmental factors or because the person was vaccinated against TB bacteria before. Quantiferon Gold measures actual exposure to give more accurate results and reduce variability in reading methods. This single-visit test does not require any additional follow-up visits or further testing if positive results are obtained. BCG vaccination will not give a false positive in the Quantiferon test as it does with the TB skin test. One of the advantages of the test is that it only requires one patient visit to draw blood, making it a more efficient and convenient option for testing. Results are available within 24 hours so healthcare professionals and patients can get quick and reliable information.
Test Accuracy:
Quantiferon Gold is an accurate test for TB infection. The QuantiFERON Gold test is a tuberculosis blood test that detects the immune response to Mycobacterium tuberculosis to differentiate between latent TB infection and active TB disease. It can be used to diagnose and monitor active TB in individuals at risk or exposed to the bacteria. Now who should get tested with Quantiferon Gold?

Who should get tested with Quantiferon Gold?
Individuals at risk for Latent Tuberculosis Infection:
Those who are at risk for TB infection, such as health care workers and individuals who have recently traveled to TB-endemic countries, should get tested with Quantiferon Gold. This includes immunocompromised hosts and those with weakened immune systems due to HIV/AIDS or other medical conditions. They should get tested as soon as possible to prevent the spread of the disease.
Individuals with Symptoms of TB Infection:
If you have symptoms of TB infection such as persistent cough, fever, night sweats, weight loss, or chest pain, get tested immediately. The earlier the diagnosis of LTBI can be made, the better the chance of successful treatment and prevention of complications.
If you have been exposed to someone with known or suspected active TB, get tested right away to see if you have been infected. This could be a close family member or co-worker who got the disease from an infected individual. Early detection can reduce your chances of getting ill and spreading the disease further.
Quantiferon Gold is an accurate test for TB infection so anyone who falls into the risk categories should get tested. In the next section, we will discuss how Quantiferon Gold is administered to ensure the results are accurate.
How is Quantiferon Gold administered?
Pre-Test Preparation:
Inform your doctor of any medications you are taking or have taken in the past before undergoing a Quantiferon Gold test. Your doctor may ask you to stop taking some medications before the test. Avoid eating or drinking anything other than water for at least 8 hours before the procedure.
How the Test is Administered:
During a Quantiferon Gold test, a small sample of blood will be drawn from your arm and sent to the laboratory for analysis. The whole process takes about an hour and can be done at most medical centers without an appointment with a doctor.
After a Quantiferon Gold test, rest your arm where the needle was inserted for several minutes to reduce swelling and bruising. Drink plenty of fluids after this type of lab work, as dehydration can occur due to fluid loss during testing. If you see any signs of infection, such as redness or pain around where blood was taken, or if there is any disruption in the gel on the tube walls, contact your healthcare provider immediately, as antibiotics may need to be prescribed to prevent further complications.
Quantiferon Gold is a safe and quick test that requires minimal preparation. But it’s good to know the risks so you can decide if this test is for you.

Quantiferon Gold FAQs
What does it mean if QuantiFERON is positive?
If someone gets a positive QuantiFERON result, it means they have been exposed to or are currently infected with Mycobacterium tuberculosis (TB exposure). This is the bacteria that causes tuberculosis (TB). TB is a contagious and serious bacterial infection of the lungs. It can be spread through close contact with an infected person and can cause symptoms such as coughing, fever, night sweats, weight loss and chest pain. Treatment usually involves antibiotics for several months to prevent further spread of the disease.
What if TB gold test is positive?
If TB Gold test is positive, it means the person has been infected with Mycobacterium tuberculosis (M. tuberculosis) and may have active TB disease. This bacteria can cause serious diseases such as tuberculosis (TB) and other diseases. In patients at high risk of M. tuberculosis infection, a second test should be done according to 2017 ATS/IDSA/CDC Clinical Practice Guidelines for Diagnosis of Tuberculosis in Adults and Children. If TB Gold test is positive, seek medical attention immediately to get an accurate diagnosis and treatment plan for active TB disease. Treatment for active TB usually involves taking antibiotics for at least 6 months or more depending on the severity of the infection. To prevent the disease from spreading, make sure to take all medications as instructed by your doctor.
What is the difference between the Tuberculin Skin Test and QuantiFERON?
A TB test, also known as a tuberculin skin test, is a skin test to detect Mycobacterium tuberculosis, the bacteria that causes tuberculosis. It involves injecting a small amount of fluid containing tuberculin, the substance used in the tuberculin skin test, into the skin and then observing for any reaction for 48–72 hours. A positive result means exposure to TB but not necessarily active infection. Another type of TB test is QuantiFERON test, a blood test that measures the body’s immune response to TB bacteria. Unlike the skin test, it only requires one visit to a healthcare provider and is recommended for those who have received the TB vaccine.
QuantiFERON test looks for active TB infection in the blood by measuring the amount of proteins released when M. tuberculosis antigens are present. This type of testing is more accurate than traditional skin tests and is recommended if there are concerns about false positives or negatives with TB skin test.
Conclusion
Quantiferon Gold is a recommended and doctor’s visit not required TB test. Easy, safe and affordable way to get tested for tuberculosis. Discounted Labs provides this test in most cities across the U.S., making Quantiferon Gold the ideal choice for a reliable tuberculosis test.
