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.
VDRL is a blood test that is used to determine whether or not you have an active syphilis infection. Although a positive VDRL test usually means that you have syphilis, that's not always the case. VDRL looks for antibodies to a non-syphilis specific protein called cardiolipin. Unfortunately, that means there can be false positive test results. False positives occur in 1 to 2 percent of the population.
