Testing for individual exposure to tuberculosis.

TB Skin Test

What is a TB test? A tuberculin skin test is done to determine whether or not an individual has been exposed to tuberculosis (TB). The process involves applying a small, safe amount of TB protein (or antigens) onto a part of the skin. If the area develops a small red bump after a couple of days, then you have been exposed to TB bacteria at some point in your life.

However, a TB test won’t be able to tell you exactly how long you’ve been infected with tuberculosis. Taking a TB skin test can help to narrow down medical complications or rule out the possibility of having TB.

Urgent Care TB Skin Test

Understanding the symptoms of tuberculosis can help you to determine the possibility of having TB or needing to get a TB test. If you’re exhibiting any of the following symptoms, give us a call today at Metro Urgent Care and we’ll get you in for an urgent care TB test:

  • An ongoing cough, persisting three or more weeks

  • Any pain during breathing and/or coughing

  • A fever

  • A cough that results in expelling blood

  • Weight loss that is unintentional or a general loss of appetite

  • Night sweats and/or chills

  • Pain in the chest area

  • General fatigue


While you may not exhibit all symptoms of tuberculosis, it helps to know what the symptoms are so that you can make an informed decision to visit a healthcare professional. If you have any questions about the symptoms you’re experiencing, you can give us a call and we can help you assess the severity and whether or not you should visit a doctor.

The following are common scenarios where an individual may be recommended to take a TB test:

  • Anyone who has been in close proximity to someone else who is known to have/had TB

  • Anyone exhibiting TB symptoms, namely night sweats, weight loss, an ongoing cough, etc.

  • Anyone who may have the human immunodeficiency virus (HIV)

  • Any healthcare workers and professionals that may have been exposed to TB patients and environments

  • Anyone who has had an organ transplant

  • Anyone with a chest x-ray result that shows abnormal results

  • Anyone with an impaired or weakened immune system


The only time a TB skin test may not be recommended for is anyone who is known to already have a TB infection, has had severe reactions to TB antigens, or develops skin rashes that may make it challenging to determine an accurate outcome of a TB test.
