HIV Screening Test


A HIV test shows if you have HIV infection (human immunodeficiency virus). HIV is a virus that attacks the immune system and destroys cells. These cells protect your body from germs which cause disease, such as bacteria and viruses. If you lack so many red cells, it can give your body problems fighting off pathogens and other diseases. An HIV test is used to determine if you had HIV infection. HIV (acquired immunodeficiency syndrome) is the virus that causes AIDS. Most HIV-patients do not have AIDS. People with AIDS have an extremely low number of immune cells and are at risk for life-threatening diseases, including hazardous infections, a severe type of pneumonia and some cancers, including Kaposi sarcomas. The Centers for Disease Control and Prevention (CDC) advises that anyone from 13 to 64 be screened for HIV as part of regular health treatment at least once. When you are at increased risk of infection, you might need an HIV check too. HIV will pass from mother to child during conception and via breast milk, so your doctor can prescribe an HIV test if you are pregnant. An antigen/antibody test looks for both antigens and HIV antibodies. Your immune system produces anticorps when you are exposed to viruses such as HIV. Antigens are foreign substances that cause your immune system to activate. If you have HIV, even before antibodies develop, an antigen named p24 is produced. Antigen / antibody testing is recommended for laboratory testing, and is now common in the USA. This laboratory test involves the taking of blood from a vein. A fast antigen / antibody screening is also available and is performed with a finger prick. HIV antibody tests only look for antibodies to HIV in your blood or oral fluid. In general, antibody tests that use blood from a vein can detect HIV sooner after infection than tests done with blood from a finger prick or with oral fluid. Most rapid tests and the only currently approved HIV self-test are antibody tests. This review tells about the future scope of the new invention towards the field of HIV /AIDS and their medicinal treatment.
