Liver Damage May be Caused By a Virus of Hepatitis
Depending on the way in which hepatitis, speaks of: – hepatitis epidemic, when it contracts directly: intake of food in poor condition (milk, butter, seafood, etc..) – Hepatitis inoculation, when contracts during a therapeutic act that behave injection of blood or other products containing, or by using contaminated equipment (needles, syringes, etc …).
It has been shown that blood from experimentally infected volunteers inoculated many weeks before the start of the first symptoms appear and remains so throughout the clinical course of acute illness and chronic carrier stage that can persist throughout life. The ability of infected persons with chronic infection varies from highly infectious cases to those who just are. The former can evolve into the latter, but rarely seen otherwise.
Diagnostics
To check whether or not someone has hepatitis, the doctor can perform two types of tests:
* Analysis of blood, or hematologic (blood is drawn with a syringe) – By biopsy, a simple test that involves removing a small piece of liver for microscopic analysis of tissue and check whether they are damaged. The most constant changes are the increase of bilirubin in the blood and increased activity of transmittance’s (liver enzymes, known by its initials ALT or AST or ALT and AST). They are between 20 and 40 times higher in the normal range. These tests not only explain if you have hepatitis, but also determine what type, A, B or C and the severity of the disease. The diagnosis is confirmed by demonstration of antibodies against hepatitis virus in the serum of patients with acute or recently been ill.
The virus and antibodies are detected by radio immunoassay test (sold test kits to detect antibodies to the virus). Other blood tests such as liver function, or enzimogramas liver may suggest liver damage may be caused by a virus of hepatitis. A liver biopsy, and laparoscopy are used to determine with certainty the degree of liver damage in the individual who is positive for antibodies to hepatitis.
