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.
Your positive skin test may mean: 1  that you are infected with the TB germ, (this is called latent TB infection), or. 2  that you have been immunised for TB in the past with a BCG vaccination (which leaves a scar on your arm), or.atent infection means you have inactive or sleeping TB germs in your body; you cannot pass these germs on to anyone else and you are not sick with TB. People with latent TB infection have a 10% risk of developing TB disease during their life.
