The Hepatitis A Virus - IgG test is used to detect and diagnose the presence of hepatitis A in the bloodstream. Hepatitis A is caused by the Hepatitis A Virus (HAV). This disease primarily affects liver functionality and is highly contagious. It entails a wide variety of distinct symptoms, including: Sharp abdominal pain  Jaundice Loss of appetite  Light-coloured stool  Dark urine  Vomiting  Diarrhoea  Flu-like symptoms Weight loss Low-grade fever  Intense itching  Joint pain The symptoms of hepatitis A appear 14 to 28 days post contact with the hepatitis A virus. So, if you start noticing any of these symptoms, make sure you take the Hepatitis A Virus - IgG test. The disease spreads via a faecal-oral route, meaning it spreads when an uninfected person ingests water or food contaminated with the faeces of an infected person. This can happen if the infected member prepares food for their family without washing their hands. Here are some other ways of catching the hepatitis A virus: Having sexual contact with an infected person Drinking polluted water Coming in contact with faeces infected with the hepatitis A virus Consuming raw shellfish that has been contaminated by the sewage water Eating food prepared by an infected person There is a chance that you might have the virus, but you will not show any visible symptoms. In that scenario, a physical examination will not be enough. Apollo 24|7 offers a comprehensive Hepatitis A Virus - IgG test that uses a blood sample and has a nominal Hepatitis A test cost. This test gauges the levels of IgG (Immunoglobulin G) antibodies in your bloodstream. These antibodies are already present in your body and help ward off the hepatitis A virus. From the test results, the following inferences can be made: A positive result indicates the presence of IgG antibodies in your bloodstream. This means that you have either had the hepatitis A virus in the past or you have been vaccinated against it. A negative result indicates the absence of IgG antibodies, implying that you have had no past exposure to the virus or have strong immunity against it. Although the disease is short-lived, it is quite painful and can cause increased discomfort. In rare cases, it might even damage your liver permanently. Hence, it is always better to take necessary precautions: Ensure you wash your hands well with soap and warm water after using the restroom.  Avoid drinking local water and drink only bottled water if you wish to drink water from outside.  Dine at reputed restaurants, and avoid eating food sold by street vendors.  Ensure you don't consume food in an area with low sanitation.  Medically reviewed by Dr. Shravan Bohra, Gastroenterologist, Apollo Hospitals Gandhinagar, Ahmedabad.
