Normal results are negative or nonreactive meaning that you dont have the hepatitis A IgM in your blood. Cautions Discusses conditions that may cause diagnostic confusion including improper specimen collection and handling inappropriate test selection and interfering substances. However hepatitis A IgM antibody will persist lifelong in the blood and is protective against reinfection.

Assays for total immunoglobulin G and immunoglobulin M IgM hepatitis A antibody and IgM-specific hepatitis A antibody assist in differentiating recent infection from prior exposure. The patients immune system makes antibodies against HAV that confer immunity against future infection. You have an active HAV infection.
When symptoms occur they typically last eight weeks and may include nausea vomiting diarrhea jaundice fever and. People with hepatitis A are advised to. Positive HAV-IgM and negative HAV-IgG IgM result may be a false positive.
The hepatitis C antibody test is a blood test that looks for hepatitis C antibodies in the bloodstream. A high IgG reactivity and a moderate level of IgM suggests hepatitis A infection in the recent past rather than current acute infection. If you test positive for them but not for IgM antibodies it means you had a hepatitis A infection in the past or had vaccinations to protect against it.
Hepatitis A or infectious jaundice is caused by hepatitis A virus HAV a picornavirus transmitted by the fecal-oral route often associated with ingestion of contaminated foodIt causes an acute form of hepatitis and does not have a chronic stage. Wear protective gloves eye wear and lab coat during all steps of this method because of infectious contamination hazards. How is the sample collected for testing.
Hepatitis A antibodies are produced in response to an infection with the hepatitis A virus. The results can be complicated as a positive test does not always mean someone has hepatitis C. The hepatitis C antibody test is the only way to check if a person has had the hepatitis C virus.

Antibody tests for hepatitis viruses may help determine the cause. The time between infection and symptoms in those who develop them is between two and six weeks. Once people have been infected they will always have antibodies in their blood.
