Do they test for hepatitis when donating blood?
All blood for transfusion is tested for evidence of certain infectious disease pathogens, such as hepatitis B and C viruses and human immunodeficiency virus (HIV). The tests used to screen donated blood are listed below.
Can you test positive for hepatitis after the vaccine?
Published studies have found that transient HBsAg-positivity can be detected for up to 18 days after HepB vaccination (up to 52 days among hemodialysis patients).Feb 18, 2022

How do I know if I had hepatitis B vaccine?
To be certain that you are protected against hepatitis B, ask for a simple blood test to check your “antibody titers” that will confirm whether the vaccination was successful.
Can you test positive for Hep B and not have it?
If the “HBsAg” was positive, this means that you are either chronically infected with hepatitis B or were recently infected. If only the “anti-HBc” was positive, it is most likely that you either had a “false-positive” test or are immune to hepatitis B infection (had hepatitis B infec- tion sometime in the past).
Can you get a false Hep B test?
Hepatitis B Antigenemia can persist for up to two weeks after vaccination, which can lead to a false diagnosis of infection. In this clinical vignette we report a case of a patient who tested positive for hepatitis surface antigen 2 months after immunization.

Overview
Hepatitis A is a highly contagious liver infection caused by the hepatitis A virus. The virus is one of several types of hepatitis viruses that cause inflammation and affect your liver's ability to function.You're most likely to get hepatitis A from contaminated food or water or from close contact with a person or object that's infected. Mild cases of hepatitis A don't require treatment. …
Hepatitis A virus (HAV) is a nonenveloped RNA virus classified as a picornavirus. HAV can survive in the environment for prolonged periods at low pH and in freezing to moderate temperatures.
This vaccine is used to help prevent infection from the hepatitis A virus. Hepatitis A infection can be mild with no symptoms or a severe illness that can rarely cause liver failure and death. Preventing infection can prevent these problems.
For specific information about hepatitis A vaccination, refer to The Pink Book, which provides general recommendations, including vaccine use and scheduling, immunization strategies for providers, vaccine content, adverse events and reactions, vaccine storage and handling, and contraindications and precautions.

HAV cannot be differentiated from other types of viral hepatitis on the basis of clinical or epidemiologic features. Diagnosis requires a positive test for antibody to HAV (anti-HAV) IgM in serum, detectable from 2 weeks before the onset of symptoms to approximately 6 months afterward. Serologic tests for total anti-HAV (IgG and IgM) are available commercially. A positiv…

Hepatitis A is caused by a virus that infects liver cells and causes inflammation.

There are several ways in which hepatitis A can be spread from one person to another. Close contact with an infected individual, such as sexual intercourse or engaging in other intimate activities increases the risk of contracting the disease considerably. Infections are also common in regions of the world with high poverty rates and poor hygiene. As a result, many children in de…
According to the World Health Organization, Hepatitis A is a liver disease caused by the hepatitis A virus. The virus is primarily spread when an uninfected (and unvaccinated) person ingests food or water that is contaminated with the feces of an infected person. The disease is closely associated with unsafe water or food, inadequate sanitation, and poor personal hygiene.
HAV is common in areas with inadequate sanitation and limited access to clean water. In highly endemic areas (such as parts of Africa and Asia), a large proportion of adults in the population are immune to HAV, and epidemics of hepatitis A are uncommon. In areas of intermediate endemicity (such as Central and South America, Eastern Europe, and parts of Asia), childhood transmission …
