Tuberculosis is one of the most prevalent diseases in the United States and worldwide. Although this is a treatable and preventable disease, tuberculosis kills millions of people each year. That's because most people become ignorant of its symptoms and don't take action until it's too late.

Luckily, it's possible to accurately test for tuberculosis and prevent it from ruining your health. The Quantiferon TB Gold Plus  TB test is an advanced blood test that gives a clear diagnosis. This type of test is more efficient and accurate than other TB tests.

Keep reading to find out more about tuberculosis, the Quantiferon test, and why you might need one.

What Are the Symptoms of Tuberculosis?

Tuberculosis can be tricky to diagnose in some cases because it might show no symptoms. For example, many people have TB bacteria in their bodies, but it's not active. This is known as latent tuberculosis and the virus can stay dormant for years.

When the bacteria become active, you will start to see some symptoms. Tuberculosis affects mainly the respiratory system. It usually spreads easier in developing countries, but developed ones also experience a significant number of TB cases every year.

Here are the most prevalent symptoms of active tuberculosis:

  • Unexplained fever
  • Night sweats as well as difficulty sleeping
  • Excessive tiredness
  • Loss of appetite
  • Involuntary loss of weight
  • Regular coughs that last for more than a few weeks and are accompanied by blood
  • Feeling chest pain when breathing normally

Keep in mind that tuberculosis is a highly contagious disease. A mere cough or sneeze is usually enough to spread the virus in the air. Other people might unknowingly breathe the contaminated air and get the TB virus in their system.

However, not everyone develops active TB. Adults with vibrant health and a strong immune system usually develop latent TB and they don't show symptoms. Latent TB can still affect your health in the future, but it's much more docile in comparison with active tuberculosis.

Who Is More Likely To Develop TB?

As mentioned earlier, cases of TB are more prevalent in low-income countries, so traveling to one of these areas might increase your risk. At the same time, people who smoke cigarettes and consume too much alcohol regularly also have a higher risk of getting active tuberculosis.

Certain health conditions that might affect your immune system could facilitate the development of tuberculosis. For example, certain cancers might weaken your natural defense mechanisms and trigger the TB virus into action.

At the same time, diabetes and malnourishment are also commonly associated with tuberculosis. Having serious kidney diseases is also a precursor to developing tuberculosis, especially if this is associated with liver problems too.

Certain medications that suppress the immune system might predispose you to TB. For example, people receiving treatment for autoimmune diseases such as lupus or rheumatoid arthritis are at greater risk.

Visiting specific regions and countries in the world might predispose you to this dangerous disease as well. For example, countries such as India, China, and Mexico register numerous cases of tuberculosis each year.

The sub-Saharan region and various places in Russia are also on the red list when it comes to tuberculosis. If you want to visit these parts of the world, make sure that you protect yourself using certain medications and/or vaccines.

How Is Tuberculosis Diagnosed?

This type of disease can be detected using a series of TB tests. If you experience the symptoms, you are urged to speak with your primary healthcare provider to find ways to treat active tuberculosis. One of the most common tests includes a skin test.

The skin test requires several doctor visits and it's not extremely accurate. In many cases, your doctor might also request an X-ray of your chest to see if your lungs are infected with this virus. Other tests include analysis of mucus to see if the tuberculosis bacteria are actively damaging your lungs.

However, the most modern and reliable test is the Quantiferon TB Gold Plus test. Here's why:

The Quantiferon TB Gold Plus Test

This is a simple test that requires just a small blood sample. It's 97% accurate, in comparison with other types of tests that can return frequent false positives. The blood sample is analyzed in a laboratory and the results are delivered in a few business days.

This type of test requires only one visit to the clinic where you draw blood for analysis. It analyzes certain enzymes and substances in your blood to see if your lungs are damaged by the active tuberculosis virus.

How are QFT-Plus results interpreted?

QFT-Plus is one of the many tools your doctor may use to determine whether TB infection is present.

There are three possible QFT-Plus results:

  • Positive – suggests that TB infection is likely
  • Negative – suggests that TB infection is unlikely
  • Indeterminate – suggests the need for further investigations or repeat testing

Your healthcare provider will explain your QFT-Plus results to you. In addition to your QFT-Plus result, your healthcare provider will take into account essential information such as your medical history, your risk of exposure to TB, and other clinical results that may be ordered.

How Is Tuberculosis Treated?

Once a diagnosis of TB is confirmed, your doctor will work closely with you to establish a treatment routine. Viral ailments are easily treated with antibiotics, but tuberculosis is more difficult to treat. Patients are usually required to follow a treatment protocol of up to 9 months.

Treatment adherence is crucial to fully cure this disease. If the treatment protocol is not respected, tuberculosis can become active again and more difficult to treat. In most cases, patients require a combination of drugs as prescribed by their doctor.

That's because many TB strains are resistant to certain drugs. Some of the TB drugs prescribed by doctors might affect your liver and you need to be aware of this. Quitting smoking is also strongly recommended and part of the tuberculosis treatment procedure. Reducing alcohol intake is also recommended as it weakens your immune system over time.

TB might be prevented using vaccinations in children. Also, latent TB, if it's discovered, can be treated with a smaller dose of medications. Again, adherence to treatment is paramount, otherwise, tuberculosis might never be cured.
