What is tuberculosis?

Tuberculosis, or TB, is a highly contagious infection that mainly affects the lungs. If not treated, it can spread to other parts of the body, such as the spine, brain, and kidneys. TB kills millions worldwide every year, but it can be treated and prevented easily. In the past, the tuberculin skin test (TST) was used to check for TB. This test required several visits to the doctor and was often unreliable. Because of this, many colleges and organizations, like the US Citizenship and Immigration Service, do not accept skin tests anymore.

Now, we have a better option called the Quantiferon-TB Gold Plus blood test. This test is cheaper, faster, and more accurate than the old TSTs. The CDC recommends this blood test for diagnosing and treating latent tuberculosis infection (LTBI). Treating LTBI can prevent it from turning into active tuberculosis. People from areas where TB is common, including parts of Latin America, the Caribbean, Africa, Asia, Eastern Europe, and Russia, should consider getting the Quantiferon-TB Gold Plus blood test. This will help detect and treat TB infection early.

Several tests can help check if a person has tuberculosis (TB).

  1. The Tuberculin Skin Test (TST), also called the Mantoux test, involves injecting a small dose of a protein known as a purified protein derivative (PPD) just under the skin of the arm. If a person has been exposed to tuberculosis (TB), their immune system reacts to the PPD. This reaction creates a raised spot at the injection site. A healthcare provider will check this bump 48 to 72 hours later. A larger bump can indicate a positive result.
  2. A blood test named the interferon-gamma release assay (IGRA) can check how much protein is released when blood cells encounter TB antigens. IGRAs are clearer than the TST. They are less likely to give false-positive results if a person has had the Bacillus Calmette-Guérin (BCG) vaccine or been in contact with non-tuberculous mycobacteria.
  3. The QuantiFERON-TB Gold Plus (QFT-Plus) test is a type of IGRA that is used to see if someone has a TB infection. This test is very precise. It measures the immune reaction to TB antigens instead of just checking for TB bacteria.
  4. The QFT-Plus test looks for interferon-gamma, a protein made by the immune system when it meets TB antigens. A small blood sample is taken and mixed with TB antigens in a lab. If the person has TB, their immune system will release interferon-gamma, which will show up in the blood sample.
  5. Many think the QFT-Plus test is more accurate and specific than the regular tuberculin skin test (TST) or Mantoux test. This is because it has a lower chance of giving false-positive results for those who had the BCG vaccine or were around non-tuberculous mycobacteria. Plus, the QFT-Plus is easier for patients since it does not require a follow-up visit for reading like the TST does.
  6. A chest X-ray can reveal signs of TB in the lungs, such as cavities or areas that are denser.
  7. A sample of sputum, which is mucus from the lungs that one clears by coughing, is looked at under a microscope to find acid-fast bacteria (AFB), the bacteria responsible for tuberculosis.
  8. A culture test is conducted to grow and identify Mycobacterium tuberculosis in a lab. This usually comes after a positive microscope test to confirm the bacteria’s presence and identify specific strains.
  9. The polymerase chain reaction (PCR) test checks for the TB bacteria's genetic material in sputum or other fluids. This test provides quick results and can detect small amounts of the bacteria.

It is important to know that choosing a test depends on the symptoms the patient shows, their risk factors, and the tests that are available. A healthcare worker can help decide which test or tests are best for each person's needs.

Reducing The Spread of TB

While we cannot completely get rid of all active TB cases, we can take steps to slow its spread. First, getting the BCG (Bacille Calmette-Guérin) vaccine is a good choice. This vaccine is made from a harmless form of TB, and it has been used since the 1920s. It is most effective in children. Even though the BCG vaccine is very popular worldwide, it does not solve every problem. Each year, there are about 10 million new active TB cases. This shows we need more ways to prevent it. TB spreads through the air. So, some simple actions, like regular TB blood testing, can help reduce the risk of getting it. This testing helps to find the disease early and stop it from spreading.

  • Ensure proper air flow. TB particles can linger in still air for several hours.
  • Get some sunlight. UV rays can destroy TB bacteria.
  • Practice good hygiene. Cover your sneezes and coughs with your elbow or a mask. This will help limit the spread of TB.

To lower the chance of getting TB, several things can help. The best way to stop its spread is by finding cases early. Most people do not spread TB to others two weeks after they begin the right treatment. So, while stopping TB is important, finding those who already have it is key. This helps make sure they don't pass it on to many people.

Should I Get a TB Test?

Tuberculosis can be difficult to find. Many people with TB do not feel sick or show signs of it. The TB bacteria can live in a person’s body for years without causing issues. Symptoms appear only when the bacteria start to act up. You should consider getting tested for TB if you have any of these signs:

  • A fever
  • Sweating at night and having trouble sleeping
  • Feeling tired
  • Not wanting to eat
  • Losing weight quickly
  • Chest pain
  • A long-lasting cough that may have blood

There are several ways to check for tuberculosis, such as chest X-rays and mucus tests. However, the best option is the Quantiferon TB Gold Plus test, often referred to as the tuberculosis test. The other methods may not always be accurate and can sometimes lead to false positives. The Quantiferon Gold test requires only 4 ml of blood. It is one of only two blood tests for TB approved by the FDA. This test can detect tuberculosis with about 94% accuracy.

How Does TB Affect the Body?

About 1.8 billion people have latent TB infection (LTBI). Most of these cases are not active. TB can be hidden for months or even years. It waits for the immune system to lower before becoming active TB disease. People with weak immune systems are at greater risk. They can develop active TB disease within days or weeks after being exposed. Their bodies cannot fight the infection well. The bacteria usually focus on the lungs. In serious cases, the infection can spread through the blood or lymphatic system. This can cause problems in the bones, organs, or skin.

Who Is Most at Risk to Develop TB?

There are several reasons why the risk of TB (tuberculosis) is higher. TB rates are usually higher in poorer countries, but it can happen anywhere in the world. TB often occurs in places with poor hygiene or in crowded areas where it spreads easily. That is why crowded spaces like college dorms or homeless shelters are common places for infection. Countries with large populations, like India and China, tend to have the most active TB cases each year.

Also, some factors raise the risk of getting TB. Using drugs or alcohol, having health issues that weaken the immune system or affect key organs, and taking certain medications for other problems can increase the risk. TB is contagious, but it does not spread as easily as other airborne illnesses. You probably won’t catch TB from someone just by walking by them. Most infections happen from being close to someone for a long time, like a family member or co-worker.

People most at risk of active TB include babies, older adults, and those with autoimmune diseases like HIV or diabetes. If you or someone you know is at higher risk and shows symptoms like a long-lasting cough, chest pain, or coughing up blood, we strongly recommend getting a tuberculosis blood test. This test can save the life of the affected person and protect those around them. The risk of being exposed to TB is greater in high-risk places like jails, hospitals, nursing homes, and shelters. If you work in these areas or have recently visited places with high TB rates, it is wise to consider a blood test for TB.

How Is TB Treated?

People with latent TB should see a doctor for preventive treatment. Their condition can get worse over time, even if they are not spreading TB right now. A common way to treat this is to start antibiotics to clear the infection before it turns into active tuberculosis. Active tuberculosis treatment can be more difficult. It can take six to twelve months for the medicine to completely get rid of the infection. Patients may feel better in a few weeks, but it is very important to keep taking the medicines the doctor prescribes for the whole time. Stopping too soon can cause reinfection, reduce resistance to the disease, and even lead to drug-resistant strains of TB. These resistant strains are more serious because they can resist the treatments meant for TB. Recovering from a drug-resistant strain may take 20 to 30 months, and patients may experience more side effects. TB is common and can lead to complications, but it can be prevented and treated properly. With modern tests like Quantiferon-TB Gold Plus, we can detect tuberculosis early, stopping serious damage. This helps us stay healthy and keeps the spread of TB down in our communities and around the world.

BCG Vaccine and TB Testing

The BCG vaccine is a shot that prevents tuberculosis, also known as TB. If you will have a TB blood test, please remember that the BCG vaccine can affect the results. The vaccine contains live bacteria, which may cause a false-positive result in a TB blood test. This reaction usually happens within 24 hours after the vaccine and can last for several days. To ensure accurate results, it is a good idea to wait at least 4 weeks after getting the BCG vaccine before taking a TB blood test.

Procedure and Duration of the TB Blood Test

The QuantiFERON-TB Gold blood test is a simple procedure with two main steps. First, a healthcare worker takes a small blood sample, about 4 mL, from a vein in your arm. This part is quick and usually takes just a few minutes. After the blood is drawn, the sample goes to a lab. In the lab, they test it with specific TB antigens. They check how your immune system reacts to these antigens. This reaction shows if the TB bacteria have infected you. You can usually get the results from the QuantiFERON-TB Gold test in about 1 to 3 days. This gives you a quick update on any possible TB exposure.

What is the difference between a TB blood test and a TB skin test?

The main difference between a TB blood test and a TB skin test is the way they find out if there is a tuberculosis (TB) infection in the body.

A TB skin test, also known as a Mantoux or PPD test, gives a small amount of purified protein derivative (PPD) in your forearm. A healthcare worker will check the area after 48 to 72 hours. They will look for bumps or swelling at the spot. This reaction helps to see if you have been exposed to TB bacteria.

A TB blood test, known as an interferon-gamma release assay (IGRA), uses a blood sample. The lab checks this sample for certain proteins. These proteins are released by immune cells when they detect TB bacteria. This test determines if you have been infected with TB bacteria.

Both tests can detect if people have TB bacteria. However, they are different in how they are done and how they find the infection. A healthcare provider can help you choose the right test for you. They will look at your medical history and any risk factors for TB.

Where can I get a TB blood test near me?

I’m sorry, but I cannot access personal data or specific locations. You can search for clinics, medical centers, or labs near you that do TB blood tests. A good way to find healthcare providers nearby is to use online directories like Google Maps or Yelp. You can also talk to your primary care doctor or your local health department. They can give you good ideas about where to get a TB blood test.

How long does it take to get the results from a TB blood test?

The results of a TB blood test usually arrive in a few days or up to a week. However, the time can vary. This depends on the lab processing the test and the number of tests they have to handle at that time. It’s a good idea to check with your healthcare provider or the testing center. They can give you more details about how long it will take to receive your TB blood test results.

Will insurance cover the cost of a TB blood test, and if not, how much does it typically cost?

Insurance coverage for a TB blood test can vary. It depends on your insurance plan and provider. It's smart to call your insurance company. Ask if they cover the test and about any costs you might have. If the TB blood test is not covered, it usually costs between $50 and $200. The price can change based on where you go and who does the test. You should contact local clinics or healthcare providers to learn about their prices for the TB screening blood test.

What do I need to do to prepare for a TB blood test?

To prepare for a TB blood test, follow these steps:

  • Talk to your doctor: It is important to share any medicines you take with your doctor. Some medications can change how accurate the test results are.
  • Follow all steps from your doctor.
  • They will tell you how to prepare for the TB blood test.
  • This may include rules on not eating or what to eat before the test.
  • Stay hydrated: Drinking enough water before your blood test can help the person taking your blood find a vein more easily.
  • Wear clothes that fit loosely or a short-sleeved shirt.
  • This will let you reach your arm easily for drawing blood.
  • Relax and stay calm.
  • If you feel anxious or stressed, it makes it harder for the phlebotomist to draw your blood.
  • Take deep breaths.
  • Try to stay calm during the procedure.

By following these steps, you can help your TB blood test go smoothly and get accurate results. It's also smart to speak with your healthcare provider. They can give you specific advice that fits your needs.

Risks Associated with TB Testing

The QuantiFERON-TB Gold blood test is generally safe. Yet, there can be some small risks involved. A common issue is light discomfort at the spot where they take your blood. You might feel pain, bruising, or swelling, but this usually goes away quickly. In rare cases, some people may feel faint or dizzy during or after the blood test.

It is important to know that test results can sometimes be wrong. The QuantiFERON-TB Gold test is quite accurate, but it can show false-positive results. This often happens for people who have had the BCG vaccine or those exposed to non-tuberculous mycobacteria. False results can lead to unnecessary worry or extra tests. That's why it is key to talk to a healthcare provider to properly understand the results.
