Rioja, a classic region of Spain, produces some of the best Tempranillo-based wines in the world, some ready to drink young, others spending years in barrel and bottle before hitting the shelves.
Testing & Diagnosis. There are two kinds of tests that are used to detect TB bacteria in the body: the TB skin test (TST) and TB blood tests. A positive TB skin test or TB blood test only tells that a person has been infected with TB bacteria. It does not tell whether the person has latent TB infection (LTBI) or has progressed to TB disease. Other tests, such as a chest x-ray and a sample of sputum, are needed to see whether the person has TB disease.
A positive reading is determined by the size of the swelling (called induration) and the presence of risk factors. For a TB skin test (also known as a PPD test), a healthcare worker will inject a small amount of fluid (called tuberculin or PPD) just under the skin on the underside of the forearm. After two or three days, you must return for the TB skin test reading. You may have a swelling where the tuberculin was injected.
