TB Skin Testing

  • We generally are the most affordable option for most of our services. We offer both one-step and two-step TB skin testing.
  • At The Vaccine Center and Travel Medicine Clinic we take appointments and walk-ins, at both of our locations, with minimal to no waiting.
  • Our highly trained medical staff follows all CDC guidelines for TB skin test administration and reading.
  • We also provide on-site TB skin testing for groups such as allied health schools and employers. Our Employee Health Services allow local companies in Las Vegas to work with a local partner that understands their needs. We can customize our services to fit most company’s Employee Health Service’s needs.
  • We also offer chest x-rays for anyone who is PPD positive (TB skin test positive) at a discounted rate.

What is the tuberculosis skin test (TB skin test)?

A TB skin test is used to determine if a person has developed an immune response to the Tuberculosis bacteria.  This can occur if someone has TB, if they were exposed to TB in the past, or if they received the BCG vaccine.

How does the TB skin test work?

  • A 0.1 ml liquid injection containing tuberculin is administered using a small needle in the top layers of  skin on the forearm.
  • You must return  within 48-72 hours after the injection where our trained health care professional will look for a reaction on the arm where the liquid was injected.
  • If a hard area or swelling is present, our health care professional will measure it with a ruler.

Depending on the size of the raised, hard area, you will have either a positive or negative TB skin test.  This is measured in millimeters.

A positive test means that the person may have either:

  1. received a BCG vaccine that has given a false positive skin reaction
  2. been exposed and infected with TB bacteria
  3. other condition that produced a false-positive reaction

Further testing is then recommended to evaluate if there is latent TB infection or TB disease.

When can I have the TB skin test done?

The Vaccine Center and Travel Medicine Clinic can administer your TB skin test on any weekday, except Thursday.  This is because if the TB skin test is administered on Thursday, the reading would need to be on Saturday and Sunday when our office is closed.

What is a 2-step TB skin test?

A 2-step TB skin test is sometimes used to prevent the chance of the first TB skin test being a false-negative reaction.  Sometimes, in persons who were infected with TB, the ability to react to tuberculin may decrease over time.  Giving a second TB skin test after an initial negative TB skin test may stimulate the immune system to give a more accurate result.

What is the process for a 2-step TB skin test?

The process of a 2-step TB skin test is similar to the 1-step TB skin test.

  1. You will have the test administered and then return in 48-72 hours for the TB read.
  2. One week or after of having the first test administered you can return for the 2nd step which includes the administration and then returning in 48-72 hours again for the TB read.

QuantiFERON®-TB Gold Testing

What is it?

The QuantiFERON®-TB Gold test (QFT-G) is a laboratory test that is taken by a blood sample. It is approved by the Food and Drug Administration (FDA) as a test for detecting tuberculosis infection and latent tuberculosis infection.

The benefits of Quantiferon testing are:

  • It requires only a single patient visit
  • Results can be available within 24-48 hours
  • It is not affected by prior BCG (bacille Calmette-Guerin) vaccination.
  • It does not boost responses measured by repeated tests, which can happen with tuberculin skin tests.

When should you use the QuantiFERON®-TB Gold Test?

QFT-G can be used in the same circumstance as the tb skin test.

For example:

  • screening after contact with a person with Tuberculosis infection
  • evaluation of recent immigrants who have had BCG vaccination
  • TB screening of high risk population groups such as health care workers, prison workers, etc.

The Vaccine Center and Travel Medicine Clinic conveniently draws the QFT-G test in house and results are available between 3-5 business days.

Chest X-Ray

The Vaccine Center and Travel Medicine Clinic also offers Chest X-Rays if necessary.

If you have a positive/abnormal tb skin test or QFT-G test, you may need additional evaluation including a Chest X-Ray.

The Chest X-Ray is used to:

  • detect any chest abnormalities
  • detect lesions in the lung that may suggest TB
  • to rule out the possibility of pulmonary (lung) Tuberculosis in a person who had a positive TB skin test or QFT-G test
