Is it normal for a tuberculosis skin test to be generally positive?

The tuberculosis skin test is also known as the PPD skin test, also known as the tuberculin pure protein derivative skin test. Whether a positive PPD skin test result is normal or not needs to be judged on a case-by-case basis.

First, the normal situation

1. Infection: If the patient has been infected with Mycobacterium tuberculosis and has recovered on its own, the PPD skin test will also be positive at this time, which is a normal physiological condition, and there is no need to worry too much and no special treatment is required.

2. Bacillus Calmette-Guérin vaccination: Since the doctor will recommend injecting the bacillus Calmette-Guérin into the newborn after birth, so as to prevent tuberculosis, antibodies will be produced in the body after the vaccination, so the above symptoms will occur.

2. Abnormal situation

However, if the body is infected with Mycobacterium tuberculosis, the body's immune system may react, resulting in symptoms such as fever, cough, and even loss of appetite. If it is not treated promptly and effectively, it may affect the health of the body, so it is abnormal.

If there are obvious uncomfortable symptoms, such as chest tightness and shortness of breath, etc., it can be improved by bed rest, or it can be treated with anti-tuberculosis drugs according to the doctor's instructions, such as rifampicin capsules, ethambutol hydrochloride tablets, etc. In daily life, we should also pay attention to the usual healthy diet, try to eat light food, avoid spicy and irritating food, and avoid eating raw, cold and cold food.
