Hepatitis virus panel
Hepatitis A antibody test; Hepatitis B antibody test; Hepatitis C antibody test; Hepatitis D antibody testThe hepatitis virus panel is a series of blood tests used to detect current or past infection by hepatitis A, hepatitis B, or hepatitis C. It can screen blood samples for more than one kind of hepatitis virus at the same time.
Hepatitis A
Hepatitis A is inflammation (irritation and swelling) of the liver from the hepatitis A virus.
Hepatitis B
Hepatitis B is irritation and swelling (inflammation) of the liver due to infection with the hepatitis B virus (HBV). Other types of viral hepatitis ...
Hepatitis C
Hepatitis C is a viral disease that leads to swelling (inflammation) of the liver. Other types of viral hepatitis include:Hepatitis AHepatitis BHepat...
Antibody and antigen tests can detect each of the different hepatitis viruses.
Antibody
Antibody titer is a laboratory test that measures the level of antibodies in a blood sample.
Antigen
An antigen is any substance that causes your immune system to produce antibodies against it. This means your immune system does not recognize the su...
Note: Hepatitis D only causes disease in people who also have hepatitis B. It is not routinely checked in a hepatitis antibody panel.
How the Test is Performed
Blood is most often drawn from a vein from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the provider gently inserts a needle into the vein. The blood collects into an airtight tube attached to the needle. The elastic band is removed from your arm. Once the blood has been collected, the needle is removed. The puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
The blood sample is sent to a lab to be examined. Blood (serology) tests are used to check for antibodies to each of the hepatitis viruses.
How to Prepare for the Test
No special preparation is needed.
How the Test will Feel
Some people feel moderate pain when the needle is inserted to draw blood. Others feel only a prick or stinging sensation. Afterward, you may feel some throbbing.
Why the Test is Performed
Your provider may order this test if you have signs or symptoms of hepatitis. It is used to:
- Detect current or previous hepatitis infection
- Determine how contagious a person with hepatitis is
- Monitor a person who is being treated for hepatitis
The test may be performed for other conditions, such as:
- Chronic persistent hepatitis
-
Hepatitis D (delta agent)
Hepatitis D (delta agent)
Hepatitis D is a viral infection caused by the hepatitis D virus (previously called the Delta agent). It causes symptoms only in people who also hav...

Normal Results
A normal result means no hepatitis antibodies or antigens are found in the blood sample. This is called a negative result.
Antibodies
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include micr...
Normal value ranges may vary slightly depending on the lab doing the test. Talk to your provider about the meaning of your specific test results.
What Abnormal Results Mean
There are different tests for hepatitis A and hepatitis B. A positive test is considered abnormal.
A positive test may mean:
- You currently have a hepatitis infection. This may be a new infection (acute hepatitis), or it may be an infection that you have had for a long time (chronic hepatitis).
Chronic
Chronic refers to something that continues over an extended period of time. A chronic condition is usually long-lasting and does not easily or quick...
ImageRead Article Now Book Mark Article - You had a hepatitis infection in the past, but you no longer have the infection and can't spread it to others.
Hepatitis A test results:
- IgM anti-hepatitis A virus (HAV) antibodies, you have had a recent infection with hepatitis A
- Total (IgM and IgG) antibodies to hepatitis A, you have a recent, or past infection, or immunity to hepatitis A
Hepatitis B test results:
- Hepatitis B surface antigen (HBsAg): you have an active hepatitis B infection, either recent or chronic (long-term)
- Antibody to hepatitis B core antigen (Anti-HBc), you have a recent or past hepatitis B infection
- Antibody to HBsAg (Anti-HBs): you have a past hepatitis B infection or you have received the hepatitis B vaccine and are unlikely to become infected
- Hepatitis B type e antigen (HBeAg): you have a hepatitis B infection and you are more likely to spread the infection to others through sexual contact or by sharing needles
Antibodies to hepatitis C can most often be detected 4 to 10 weeks after you get the infection. Other types of tests may be done to decide on treatment and monitor the hepatitis C infection.
Risks
Risks associated with having blood drawn are slight, but may include:
- Excessive bleeding
- Fainting or feeling lightheaded
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)

Blood test - illustration
Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

Hepatitis B is also known as serum hepatitis and is spread through blood and sexual contact. It is seen with increased frequency among intravenous drug users who share needles and among the homosexual population. This photograph is an electronmicroscopic image of hepatitis B virus particles.

Erythema multiforme, circular lesions - hands - illustration
Erythema multiforme lesions are circular and may appear in concentric rings (often called target lesions). Target lesions may also be associated with other medical conditions such as herpes infection, streptococcal infection, tuberculosis (TB), or as a reaction to chemicals or medications.
