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.
This subsequent testing allows for a boosted reaction from a previous infection to read positive. Return to your health care provider within 48 to 72 hours from the second TST and get a test reading. A negative two-step TB test indicates no current or previous TB infection. A positive two-step test indicates infection and additional evaluation to rule out current TB infection is performed.
