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.
Key Points. 1  HIV testing shows whether a person is infected with HIV. HIV stands for human immunodeficiency virus. HIV is the virus that causes AIDS (acquired immunodeficiency syndrome). AIDS is the most advanced stage of HIV infection. The Centers for Disease Control and Prevention (CDC) recommends that everyone 13 to 64 years old get tested for HIV at least once and that people at high risk of infection get tested more often.
