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.
As little as 5 millimeters of induration is a positive test for someone with an impaired immune system or a known TB exposure. A trained reader needs to interpret the TB test. Most people with a positive TB skin test donât recall symptoms of tuberculosis. They may have a normal chest X-ray, as well. Nevertheless, they still likely have a small number of tuberculosis bacteria hiding somewhere in the lungs.
