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.
If the TB test is positive but there is no other evidence suggesting infection, a TB expert should be consulted. Follow-up symptom screening and chest X-ray should be performed at 3, 6, 12, 18, and 24 months, because the risk of developing active TB from LTBI is highest during the first 2 years.
