A tuberculin skin test is done to find people who have tuberculosis (TB), including: People who have been in close contact with someone known to have TB. Health care workers who are likely to be exposed to TB. People with TB symptoms, such as an ongoing cough, night sweats, and unexplained weight loss. People who have had an abnormal chest X-ray. People who have had a recent organ transplant or have an impaired immune system, such as those with human immunodeficiency virus (HIV).
The most important precaution you can take to prevent TB is to avoid being around people with active TB, which is highly contagious, especially if you have already tested positive for latent TB. More specifically:
Don't spend long periods of time with anyone who has an active TB infection, especially if they have been receiving treatment for less than two weeks. In particular, it is important to avoid spending time with TB patients in warm, stuffy rooms.
If you are forced to be around TB patients, for example if you work in a care facility where TB is currently being treated, you will need to take protective measures, such as wearing a face mask, to avoid breathing in the TB bacteria.
If a friend or family member has active TB, you can help to rid them of the disease and lessen your own risk of contracting it by ensuring that they strictly follow treatment instructions.
Vaccination: All new born and infants should be given the Bacillus Calmette-Guerin (BCG) vaccine to protect them against TB. The vaccine enables the child to develop antibodies against the causative organism (Mycobacterium tuberculosis) of TB. 2. Keep your immunity high: Most of you might have come in contact with TB bacilli but have not developed the disease because of protection offered by vaccination you received in childhood. However, the vaccine cannot provide life-long protection. That's why people with a lowered immunity are at a higher risk of infection. Therefore, a healthy lifestyle is important to prevent TB. Include fresh fruits and vegetables in your diet. Eat a complete meal that includes carbohydrates, proteins and fats. Quit smoking and drinking alcohol, exercise regularly and stay fit.
If you have latent tuberculosis, you may need to take just one type of TB drug. Active tuberculosis, particularly if it's a drug-resistant strain, will require several drugs at once The most common medications used to treat tuberculosis include: Isoniazid.
Test Method 1 : The doctor or nurse will swab the skin of your inner forearm with alcohol. You will then get a small shot that contains PPD under the top layer of your skin. You may feel a slight sting. A bump or small welt will form, which usually goes away in a few hours.
After 48 to 72 hours, you must return to your doctor's office. A nurse or other medical professional will check the area where you received the shot to see if you've had any reaction to the PPD. There's a very small risk of severe redness and swelling on your arm, especially if you've had a previous positive PPD test and you're having the test again.
