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.
Initial testing for hepatitis C has three parts. The first test, the HCV antibody test, sees if you have been exposed to the virus. The second test is the viral load test, and it detects whether you were merely exposed or if you actually have hep C. If that test is positive, then a genotype test is done to find out what kind of hep C you have.
