Tuberculosis (TB) is a serious bacterial infection that affects the lungs. The TB test is a simple skin test that helps to detect the presence of TB bacteria in the body. During the test, a small amount of tuberculin is injected under the skin, and the reaction is observed after 48-72 hours. But what happens if you accidentally put lotion on a TB test?
What is a TB Test?
Before we dive into the effects of putting lotion on a TB test, let’s first understand what a TB test is. The TB test, also known as the Mantoux test, is a way to determine whether a person has been infected with TB bacteria. The test involves injecting a small amount of tuberculin under the skin and observing the reaction after 48-72 hours.
What Happens if You Put Lotion on a TB Test?
Putting lotion on a TB test can interfere with the results of the test. The lotion can block the entry of the tuberculin into the skin, preventing the test from working correctly. This can lead to a false negative result, which means that the test may show that you do not have TB bacteria in your body, even if you do.
What to Do if You Accidentally Put Lotion on a TB Test?
If you accidentally put lotion on a TB test, it is important to inform the healthcare provider who administered the test. They may advise you to retake the test after a certain period of time or recommend additional testing to confirm the results.
Precautions to Take Before a TB Test
To ensure accurate results of the TB test, it is important to follow the instructions given by the healthcare provider. Some precautions that you can take before the test include:
- Avoiding the use of lotions, creams, or ointments on the area where the test will be administered
- Avoiding the use of alcohol or other disinfectants on the area
- Informing the healthcare provider about any medications or medical conditions that you may have
The TB test is an important diagnostic tool that helps to detect TB bacteria in the body. Accidentally putting lotion on the test can interfere with the results and lead to a false negative. Therefore, it is important to follow the instructions given by the healthcare provider and take necessary precautions before the test. If you do accidentally put lotion on a TB test, inform the healthcare provider immediately to ensure accurate results.
