Examination Hepatitis A Diagnosis Tests

Many people still confuse how to diagnose hepatitis A virus, or where we can do hepatitis A diagnosis tests. A complete medical history and physical examination provide valuable information about your signs and symptoms, and it is likely that you have been exposed to HAV Hepatitis A Virus (HAV). While taking a medical history, your hepatitis A physician doctor will ask you where you have traveled, if you work or have a child in kindergarten, and if you live with a person known to have contracted hepatitis A.

If you have been exposed to hepatitis A, you have blood tests to study liver function and see if your liver is damaged or inflamed. Hepatitis A diagnosis like blood tests to study liver function include :
- The Bilirubin. When bilirubin accumulates in the blood, may indicate hepatitis disease.
- Albumin. Below normal levels may indicate hepatitis or other liver problems.
- Prothrombin time, a blood test that measures the time it takes for blood to clot. A prothrombin time may be caused by disease or liver disease.

Blood tests in hepatitis A diagnosis may be performed to determine if the liver is damaged or inflamed include :
- Alanine aminotransferase (ALT). When the liver is damaged or diseased, ALT is released into the bloodstream, causing levels of the enzyme increased.
- Aspartate aminotransferase (AST). When damaged tissues or organs like the heart or liver, AST is released into the bloodstream. The amount of AST in the blood is directly related to the degree of tissue damage.
- Alkaline phosphatase (ALP). Large amounts of alkaline phosphatase in the blood can indicate liver damage.
- Lactic dehydrogenase (LDH). Many diseases can cause elevations in the level of LDH. In addition to proof of DHL, the doctor usually will run more tests to confirm a diagnosis of hepatitis A.

If the hepatitis A diagnosis tests show that the liver is inflamed, you have an antibody (anti-HAV) test on a sample of his blood. The presence of antibodies against HAV indicates that HAV infection is the most likely cause of hepatitis. If test results show that anti-HAV hepatitis A does not multiply in your body, your doctor may do other blood tests to determine if hepatitis virus hepatitis B, hepatitis C or Epstein -Barr virus (which causes infectious mononucleosis, or mono) is the cause of his hepatitis.

Early Detection of Hepatitis A Virus

If you suspect that you have been exposed to the virus and have not been vaccinated or infected, contact your doctor. If you take hepatitis A diagnosis tests and receive an injection of immune globulin (IG) within 2 weeks of exposure to hepatitis, you may not have symptoms of infection with HAV.

Routine vaccination of hospital personnel, food handlers and child care workers and attendees Center does not occur at this time because the risk of infection is generally higher than the general community. However, some centers have child care workers get the shot because it works so well to prevent the disease. There are also very low likelihood of vaccine side effects. If outbreaks of HAV infection occur in these environments, people who have been exposed to the virus should receive an injection of immune globulin (IG).

HAV Hepatitis A Causes Virus

Hepatitis A caused by a HAV virus (HAV is Hepatitis A Virus) which multiplies in the cells of the liver and excreted in faeces.

How Can Hepatitis A Virus (HAV) Spread

Hepatitis A virus is present in the feces (stool) of a person who has hepatitis A. The virus is spread most often when people put food or objects contaminated with HAV in feces in the mouth.

A large number of people who contracted the virus after drinking contaminated water, since in many parts of the world, drinking water is contaminated by raw sewage. The virus can also be transmitted by eating raw foods (such as raw seafood), fruits and vegetables unpeeled, washed with contaminated water. Outbreaks of hepatitis A caused by contaminated drinking water are rare in the United States, because water supplies are treated to kill viruses and other pests.

In United States and Canada, HAV (hepatitis A virus) is spread primarily among people who have close contact with someone who has the virus. You can be infected with Hepatitis-A-Virus if :

• Eating food prepared by someone who did not wash their hands after using the toilet or changing diapers.
• Do not wash hands after changing diapers.
• Consumption of raw shellfish or undercooked which are harvested in waters contaminated by raw sewage.
• Is it a man and have sex with men.

Outbreaks of hepatitis A among children in residential day care occur because children, especially those layers, you can get fecal matter in their hands and then touch objects that other children put in their mouths. Doctors at the centers of day care can transmit the virus if it does not wash hands thoroughly after changing a diaper.

It is very rare for hepatitis A is spread by infected blood or blood products. Not known to be transmitted by saliva or urine. Some people fear that the infection is linked to hepatitis, or increases the risk of acquired immunodeficiency syndrome (AIDS). This is not true. The hepatitis A is not related to human immunodeficiency virus (HIV) that causes AIDS, or increase their risk of HIV infection. A person can be infected with both hepatitis and HIV, but the two infections have nothing to do with each other.

Incubation periods, and contagion

After the HAV Hepatitis A Virus enters your body, the amount of virus from 2 to 7 weeks. Incubation period average is about 4 weeks.  Feces and other body fluids contain the highest levels of the virus 2 weeks before symptom onset. This is when they are most contagious, but can still transmit the virus after the onset of symptoms.
