What to Expect at Your TB Test Visit

Walk-In TB Skin Test FAQs

Purified Protein Derivative (PPD) test is administered to check the presence of tuberculosis bacteria ‘Mycobacterium Tuberculosis’ in a person’s body. The test is done by injecting a small amount of sterile solution, PPD tuberculin, in your forearm. PPD test results are assessed based on your immune system’s reaction to the injected PPD solution.

None. You may come at any time of the day, and you are not required to be on fasting for a PPD skin test.

The problem with the Tuberculosis is that you may have it and yet you don’t know about it, until the latent TB bacteria in your body becomes active. When the TB bacteria becomes active, you will experience these initial symptoms, which will indicate that you need to see a doctor and get the TB test done:

 
  • Persistent cough
  • Loss of appetite, resulting in unintentional weight loss
  • Fever
  • General fatigue
  • Night sweats
  • Chest pain with coughing
 

Also, it’s recommended to get a TB test done as soon as possible if you have been exposed to a person with TB.

We have a 2-step TB test procedure that involves two visits to our clinic within 48-72 hours. The first step is for the placement of PPD tuberculin in your forearm. In the second step, you’ll be asked to visit again within 48-72 hours, during which our provider will assess how your body has responded to the injected tuberculin.

 

Note: Do not forget to visit the clinic within the stipulated time of 48-72 hours for test assessment. Missing the timeline would require you to go for the PPD skin test again from the beginning.

$25 in total fee for the test and the reading.

A number of factors may affect your TB skin test result. A few of them are:

 
  • If you have recent contact with another person infected with TB
  • If you work at a medical facility, hospital, clinic, care center, or medical lab
  • If you had TB in the past
  • Have received an organ transplant
  • Being HIV positive
  • Coming recently from a country where TB is common
  • Have used injected drugs
 

Considering these, a PPD test may produce different results, such as ‘Positive,’ ‘Negative,’ ‘False Positive,’ and ‘False Negative.’ In case your TB test doesn’t yield a confirmed result, we have other methods for more detailed diagnosis.

No. A positive TB skin test (or TB blood test) only tells that you’re infected with TB bacteria. It doesn’t tell whether you have an inactive or latent TB infection (LTBI), or it has progressed to TB disease.

 

Once your TB skin test has confirmed that you’re infected, it will need a further diagnosis, such as a chest X-ray and a sample of sputum, to be able to confirm whether you have TB disease or not.
