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.
What is a TB blood test? The tuberculosis (TB) blood test, also called an Interferon Gamma Release Assay or IGRA, is a way to find out if you have TB germs in your body. The TB blood test can be done instead of a TB skin test (Mantoux). There are two kinds of TB blood tests: QuantiFERONÂ®-TB; T-SPOTÂ®.TB ; You should have a TB blood (or TB skin test) if you: 1  have had frequent close contact with someone who has active TB disease, 2  have lived in a country where many people have TB, 3  work or live in a nursing home, clinic, hospital, prison, or homeless shelter, or. 4  have HIV infection or your immune system is not very strong.
