Tuberculosis (TB) is a responsible contamination that does not affect you. Seed Mycobacterium tuberculosis causes this position and spreads through the air. Storms occur when the immune system is weakened. It causes weight loss, fever, nocturnal sweating and coughing. There are all kinds of tests that are inexpensive to determine TB, and skin testing is considered the most used technique. What does that mean? a positive What does the TB Skin Test look like? What does it really mean?
Is it a TB test?
The tuberculin skin test (also known as the Mantoux Tuberculinet test) is a test to determine if a person has ever been exposed to tuberculosis (TB). The laboratory technician applies a small amount of TB antigen to the skin, usually inside the upper skin layer on the inside of the forearm. If the skin has been previously exposed to Mycobacterium tuberculosis (TB) bacteria, the skin reacts to the antigen and develops red patches over a period of two days.
The TB protein or antigen used during the test is commonly referred to as purified protein creation (PPD). The skin is exposed to a specific number of PPDs to see how the skin reacts. In most cases, the analysis is fairly accurate. Doctors have the opportunity to request a skin test if they notice signs and symptoms of TB.
TB How do I read a skin test?
When interpreting a skin test, the physician looks for two factors The amount of firm developed a few days after the test and the risk of having TB. You can have negative or positive Tuberculo test results.
Usually (negative results)
If a negative result is obtained, there is no TB. This means that there are no difficult bumps seen after exposure to TB antigens. Also, if a bump is seen, it is considered normal, but not less than 5 mm.
Abnormal (positive result)
The test is considered positive Under proper living conditions:
- There is a sturdy bump with dimensions of 5 to 9 mm. This usually means that you are in one of the highest risk groups.
- If you have a stroke volume of 10-14 mm, your risk is lower.
- If the bump is greater than 15 mm, you are in the low risk group.
Positive results of the TB skin test: what does it mean?
A positive The test result means that you are considered a carrier of the tubercle bacillus. You also have a positive chest X-rays, but there is no sign of TB. There is no sign of TB that your infection is not contagious and you cannot pass it on to others. In other words, there is potential consumption.
It is important to note that the test cannot tell if a person actually has TB or has been vaccinated for TB in the past. Therefore, it is important to perform other tests, such as x-rays and sput culture, to prove whether TB infection is active.

False Positive and Negative Results
False positive results can be obtained positive TB Skin TestIf you have received Bacillus Calmette Guerin (BCG) vaccine in the past. However, BCG is not given in the United States. For example, because it is still used in other states. This suggests that it is not a good idea to let people test themselves for TB to prove if the TB virus is working. One in five people who may be contaminated show little or no response to the antigen. For example, using steroids or undergoing chemotherapy can literally give false negative results. An x-ray, sputum test, or CT scan is needed to show infection.
Other things can affect your TB test results
There are many other things that can greatly affect a Tuberculo set test. For example:
- If you use drugs that destroy the immune system, your test results are impressive.
- Immunizations for some infectious diseases such as mumps, measles, chicken po, or polio can affect your TB results, especially if you have been vaccinated about 6 months prior to TB. Recent infectious diseases can still affect test results.
- Vaccination at a very early stage can produce different results. Your immune system will react to the TB virus after about 2-10 months.
- The Tuberculoset test may not yield clear results in children younger than 3 months. This is because their immune system is not yet sufficiently developed to cause a reaction.
- People who systematically obtain TB skin tests often do not react to TB skin tests. This is more common among medical employees.
