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 firm bump that is 10 mm (0.4 in.) in size suggests a TB infection in people who are in a moderate-risk group. A firm bump that is 15 mm (0.6 in.) in size suggests a TB infection in people who are in a low-risk group. A positive tuberculin skin test does not mean you have a contagious (active) infection. The test cannot tell if the infection is active or inactive (latent TB).
