PPD stands for Purified Protein Derivative, and the PPD tuberculin vaccine is used for diagnosing tuberculosis (TB) infection. It is not actually a vaccine in the traditional sense that it prevents or treats the disease. Instead, it is a diagnostic tool.
The PPD tuberculin vaccine contains a small amount of purified proteins derived from the bacteria that cause tuberculosis. It is injected just beneath the skin, usually on the forearm, and after 48 to 72 hours, At VCare Our Doctor examines the injection site to see if there is a reaction.
The reaction to the PPD tuberculin vaccine helps determine if a person has been infected with the bacteria that cause tuberculosis. If someone has been exposed to TB in the past, their immune system may react to the vaccine, resulting in a localized swelling or redness at the injection site. This reaction does not necessarily indicate active tuberculosis disease but rather exposure to the bacteria.
It is important to note that the PPD tuberculin vaccine is not used as a standalone diagnostic tool. It is typically used in conjunction with a medical evaluation, including a medical history, physical examination, and other tests such as chest X-rays, sputum tests, and blood tests, to diagnose tuberculosis accurately.
If the PPD tuberculin vaccine shows a positive reaction, further tests may be conducted to determine if the infection is active or latent. Active tuberculosis requires immediate treatment, whereas latent tuberculosis may require preventive treatment to prevent the infection from becoming active in the future.
It is essential to consult with VCare tuberculosis specialist, for accurate diagnosis, interpretation of the PPD tuberculin vaccine results, and appropriate management of tuberculosis infection.
