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.
There are 2 simple blood tests for Hep C. The Antibody Test shows whether you have ever been exposed to the Hep C virus. The Viral Load Test (also known as the HCV-RNA test) can tell if the virus is currently in your blood, and how much of it you have (your viral load).
