After Harry had already heavily attacked Quentin Alexander's first performance, he then sternly turned on him for being 'disrespectful' when he called the show 'whack' - ending with the contestant storming back on the stage right up to a few feet from Harry and the judges' table.
Hepatitis C tests are used to screen for and diagnose a hepatitis C virus (HCV) infection, to guide therapy and/or to monitor the treatment of an HCV infection. An HCV antibody test is used to screen for past exposure and current infection. It detects the presence of antibodies to the virus, indicating exposure to HCV. This test cannot distinguish whether someone has an active or a previous HCV infection.
These are the names of two types of tests that detect antibodies in your blood. To determine if hepatitis C antibodies (HCAb or anti-HCV) are in your blood, doctors use a screening test called ELISA, which stands for Enzyme-Linked ImmunoSorbent Assay.
