Screening Tests For Hepatitis B

Hepatitis B Titer – Hep B Surface Antibody Test Results Overview

Your blood may be screened for HBV for many different reasons. The three tests generally include HBsAg, antibody to HBsAg, and antibody to hepatitis B core antigen. This allows the healthcare provider to know whether you could benefit from vaccination, or if you have active or chronic hepatitis B and need counseling, care, or treatment.

You may be routinely screened if you are pregnant, are donating blood or tissue, need immunosuppressive therapy, or have end-stage renal disease. You will also be screened if you are in groups that are at higher risk for HBV.

Identifying Patterns Of Risky Behavior

Screening is an opportunity to draw attention to the clients behaviors that put him or her at risk for contracting :

  • Ask for the clients perception of his or her risk for having contracted : How likely do you think it is that the test will be positive?
  • Listen for and identify behaviors that put the client at risk for contracting , B, and C and HIV, especially unprotected sex and sharing injection drug paraphernalia.
  • Assess the clients alcohol consumption.

What Does A Reactive Result To A Hepatitis B Test Mean

The meaning of a reactive result for a hepatitis B test depends on the type of test performed, according to the Hepatitis B Foundation. The three most common blood tests detect the presence of hepatitis B surface antigens, hepatitis B surface antibodies or hepatitis B core antibodies.

In the hepatitis B surface antigen test, a reactive or positive result means that a person is currently infected with the hepatitis B virus, explains the Hepatitis B Foundation. Reactive results from the hepatitis B surface antibody test means that people are now immune to the virus because they have been infected in the past and their immune systems produced antibodies to fight the infection. For the hepatitis B core antibody test, a reactive or positive result can mean either that a person is currently infected with hepatitis B virus or have been some time in the test. A reactive result for this test can also be a false positive, meaning that the person has never been infected with the virus.

What Is This Test

This test looks for antibodies called IgM in your blood. The test is used to find out whether you are actively infected with the hepatitis B virus .

HBV has a central core and a surrounding envelope. Your immune system makes IgM antibodies to the core of HBV during the active stage of infection. It can take 60 to 150 days to develop symptoms of hepatitis B after you become infected. Hepatitis B core IgM antibodies begin to appear in your blood several weeks after you are first infected with HBV. People who have had the hepatitis B vaccine will not have the core antibody in their blood.

HBV is one of 5 hepatitis viruses. The others are hepatitis A, C, D, and E. Most hepatitis infections are caused by these 5 viruses. HBV is spread through blood, seminal fluid, and vaginal secretions. The virus causes an infection in the liver. In most cases, this virus clears up on its own within 6 months. But in a small portion of adults and a larger portion of children, the virus does not go away. This is especially true for newborns. This is called having a chronic infection. It may lead to liver cell damage scarring, or cirrhosis or liver cancer.

What Abnormal Results Mean

Understanding Hepatitis B Serology Results

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 , or it may be an infection that you have had for a long time .
  • 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 antibodies, you have had a recent infection with hepatitis A
  • Total antibodies to hepatitis A, you have a previous or past infection, or immunity to hepatitis A

Hepatitis B test results:

  • Hepatitis B surface antigen : you have an active hepatitis B infection, either recent or chronic
  • Antibody to hepatitis B core antigen , you have a recent or past hepatitis B infection
  • Antibody to HBsAg : 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 : you have a chronic 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.

Question 5 What Is The Natural History Of Hepatitis B Surface Antibody During Acute Hepatitis B Infection And Convalescence

HBsAg can be detected in the blood 4 to 10 weeks after exposure. This corresponds to onset of symptoms and viremia detectable by nucleic acid amplification methods. Most hepatitis B infections are self-limited and are associated with disappearance of HBsAg within 4 weeks of onset of symptoms. The anti-HBs then appears and increases to a plateau level that persists indefinitely.2

How To Get Tested

Hepatitis B testing is typically prescribed by a doctor and performed in a hospital, lab, or other medical setting. Taking a hepatitis B test requires a blood sample, which can be collected by a health care professional.

For laboratory-based testing, blood is drawn from a patientâs vein. After blood is collected, the sample is sent to a laboratory for analysis.

How The Test Is Performed

Hepatitis B Surface Antibody Ql Reactive Mean

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 . 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 tests are used to check for antibodies to each of the hepatitis viruses.

How Much Does The Test Cost

The cost of hepatitis B testing depends on the tests that are performed, where the test is conducted, and a patientâs health insurance coverage. When testing is ordered by a doctor, patients with health insurance may find it helpful to discuss the cost of testing with their health insurance company as they may be responsible for testing costs as well as other out-of-pocket costs such as copays and deductibles.

For patients without health insurance or for whom insurance doesnât cover the cost of testing, it may be helpful to discuss the cost of hepatitis B testing with a doctor or hospital administrator.

The cost of at-home hepatitis B testing starts around $45. At-home test kits may also test for additional types of viral hepatitis in the same sample. The cost of test panels that look for more than one type of viral hepatitis start around $80.

Discusses Physiology Pathophysiology And General Clinical Aspects As They Relate To A Laboratory Test

Hepatitis B virus infection, also known as serum hepatitis, is endemic throughout the world. The infection is spread primarily through blood transfusion or percutaneous contact with infected blood products, such as sharing of needles among injection drug users. The virus is also found in virtually every type of human body fluid and has been known to be spread through oral and genital contact. HBV can be transmitted from mother to child during delivery through contact with blood and vaginal secretions, but it is not commonly transmitted via the transplacental route.

The incubation period for HBV infection averages 60 to 90 days . Common symptoms include malaise, fever, gastroenteritis, and jaundice . After acute infection, HBV infection becomes chronic in 30% to 90% of infected children younger than 5 years of age and in 5% to 10% of infected individuals age 5 or older. Some of these chronic carriers are asymptomatic, while others progress to chronic liver disease, including cirrhosis and hepatocellular carcinoma.

Hepatitis B surface antigen is the first serologic marker, appearing in the serum 6 to 16 weeks following HBV infection. In acute cases, HBsAg usually disappears 1 to 2 months after the onset of symptoms with the appearance of hepatitis B surface antibody . Anti-HBs also appears as the immune response following hepatitis B vaccination.
