What is tuberculosis (TB)?

Tuberculosis (TB) is an infection caused by exposure to Mycobacterium tuberculosis, which spreads rapidly from person to person, mainly through coughing and sneezing. TB primarily injures the lungs but also damages other vital organs like the brain, spine, and kidneys.

Who has a higher risk of getting infected with tuberculosis (TB)?

Specific individuals have a higher risk of TB infection after exposure. These include individuals who:

  • Work or live where TB is more common, such as in the healthcare industry, shelters for people without homes, and jails.
  • Have weak immune systems
  • Have other diseases, such as HIV/AIDS, autoimmune disorder, or diabetes, that make it hard for your body to fight TB bacteria
  • Have an alcohol abuse disorder or use illegal drugs
  • Were not appropriately treated for TB in the past
  • Children under the age of 5
  • Adults 55 or older

Additionally, it is important to note that NOT all individuals infected with TB bacteria display symptoms. Therefore, there are two types of TB conditions:

  • Latent TB infection – the TB bacteria lives dormant in the body without any symptoms.
  • Active TB – am individual gets sick from the TB germs. Individuals can almost always cure TB disease with antibiotics. But if not appropriately treated, it can become fatal.

How is tuberculosis tested?

This is a blood-based interferon-gamma release assay used to help in the diagnosis of tuberculosis by measuring a patient’s immune response to certain TB antigens, QuantiFERON-TB Gold Plus (QFT-Plus) aids in the diagnosis of mycobacterium tuberculosis infection. The Gold Plus panel is approved by the FDA to screen TB.
