Pecorino Romano is a hard, salty Italian cheese, often used for grating, made out of sheep's milk (the Italian word pecora, from which the name derives, means sheep). Pecorino Romano was a staple in the diet for the legionaries of ancient Rome. Today, it is still made according to the original recipe and is one of Italy's oldest cheeses. Most of its production occurs in Sardinia. On the first of May, Roman families traditionally eat Pecorino with fresh fava beans during a daily excursion in the Roman Campagna.
HIV Tests For Screening and Diagnosis. There are three types of HIV diagnostic tests: antibody tests, antigen/antibody tests, and nucleic acid (RNA) tests. Antibody tests detect antibodies, proteins that your body makes against HIV, not HIV itself.
The oral test may have a slightly lower sensitivity than blood-based tests. Urine: This test uses a urine sample to detect HIV antibodies (again, not the virus itself) in urine. The accuracy of urine tests is somewhat less than that of blood and oral fluid tests. Positive results must be confirmed with a Western blot.
