What happens if you touch the water on the skin of tuberculosis

A tuberculosis skin test usually refers to a tuberculin test. Touching water after the tuberculin test may cause local infection and affect the test results.

1. Local infection: The tuberculin test is a method of injecting tuberculin into the inner forearm and judging whether there is a tuberculosis bacillus infection based on the redness, swelling and induration of the injection site. If the patient does not take good care of the skin when performing the tuberculin test, it may lead to bacterial invasion, causing an inflammatory reaction, and local pain, itching and other symptoms.It is recommended that patients can use drugs such as amoxicillin capsules, cefixime granules, etc., for anti-inflammatory treatment under the guidance of a doctor. At the same time, it is also necessary to pay attention to maintaining local cleanliness and hygiene, and avoid getting wet, so as not to aggravate the condition.

2. Affect the test results: It may also affect the test results. Because the tuberculin test is an immunological test, it is mainly used to determine whether there is a Mycobacterium tuberculosis infection by looking at the redness or induration at the injection site. If the patient's skin is irritated, it may cause redness or induration to disappear, which can affect the test results. It is recommended that patients can wait for a period of time before undergoing the examination, which generally does not cause adverse effects on the body.

In addition, in daily life, patients should pay attention to rest, avoid overwork, and try to eat light and easy-to-digest foods, such as millet porridge, pumpkin porridge, etc. If there is obvious discomfort during the period, it is necessary to seek medical attention in time to avoid delaying the condition.
