Laboratory Findings And Diagnostic Tests

Understanding Hepatitis B Serology Results

Serum HBsAg and anti-HBs are the most useful screening tests for chronic HBV infection or immunity to HBV. HBsAg is present in most chronically infected persons. Lack of anti-HBs in an unvaccinated HBsAg-negative person indicates susceptibility to HBV infection.3

Screening for HBsAg is recommended at the first prenatal visit for all pregnant women.3,109 Women in labor without HBsAg test information should have HBsAg serology on arrival. In addition, pretested women who have a history of certain risk factors should be retested at the time of admission to the hospital for delivery.3,110

Analysis Of The Positive Results And Influencing Factors Of Hepatitis B Antibody In Hospitalized Neonates With Aghbs Positive Mothers

  • Department of Neonatology, The Second Affiliated Hospital and Yuying Childrenâs Hospital of Wenzhou Medical University, Wenzhou, China

Purpose: To investigate the results of positive antibody to hepatitis surface antigenin hospitalized neonates whose mothers were hepatitis B surface antigen positive and to explore the influencing factors.

Method: The study subjects were hospitalized neonates whose mothers were positive for AgHBs. According to the serological test results of five immune markers of hepatitis B virus , they were divided into positive for anti-HBs and negative for anti-HBs. Retrospective analysis of relevant factors affecting results of anti-HBs.

Result: 269 cases were positive for anti-HBs and 64 cases were negative for anti-HBs. Univariate analysis results: the number of hepatitis B immunoglobulin injections after birth, whether HBIG was injected within 6h, whether Hepatitis B vaccine was injected within 6h, whether combined immunization within 12h, whether Hep B was vaccinated on time after discharge, whether preterm birth, and whether low birth weight infants were statistically significant . The results of binary logistic regression analysis: HBIG injection time 6h , combined immunization time 12h were protective factors premature infants , ALB/GLO and failure to complete three vaccinations on time were risk factors .

When To Contact A Doctor

A person should contact a doctor if they think that they may have had exposure to hepatitis B. The doctor can run a blood test to look for the presence of the infection and determine the next steps.

People who are concerned about contracting the virus may want to ask a doctor about getting the hepatitis B vaccine. This will protect them from future infections.

People who are living with a known case of chronic hepatitis B should visit a doctor regularly for screenings and blood tests to monitor the virus.

Medical staff members at substance abuse treatment programs might assume the primary role for screening individuals for and explaining the screening process and test results. Opioid treatment programs with medical staff members should screen for and C at intake and periodically as indicated. In programs without onsite medical staff, clients may be referred elsewhere for screening with minimal involvement of the substance abuse treatment program.

Regardless of the type of program, counselors should have a basic understanding of the importance of screening, the screening process, and the meaning of the results. Counselors can encourage clients referred for screening to follow through and complete the screening and evaluation process . Clients might feel anxious about being diagnosed with hepatitis, and they might delay or avoid getting screened.

Q:What Does Hepatitis B Core Antibody Being Positive Mean?

A:Hepatitis B Core Antibody is one of the blood tests available to diagnose hepatitis B. It is produced by the body in response to a part of the hepatitis B virus.

The meaning of this test often relies on the results of two other tests: Hepatitis B Surface Antigen and Hepatitis B Surface Antibody .

A positive test has two possible meanings:

  • A person is infected with hepatitis B virus, or
  • A person was infected in the past but the infection has been cleared.

Hbc Antibody Positive/hbs Antigen Negative/hbs Antibody Negative

The HBc antibody positive/HBs antigen negative serotype is further divided into naïve and occult types . However, since HBV reactivation is often observed in HBc antibody positive/HBs antigen negative cases, it may be preferable to divide HBc antibody positive/HBs antigen negative cases based on whether they are positive or negative for HBs antibodies. For HBc antibody positive patients, perhaps HBV reactivation is induced by rituximab. Although Hui et al reported a 3%-25% reactivation rate, prophylactic treatment may be desirable since the mortality is relatively high after reactivation occurs. In 2013, Huang et al conducted a randomized controlled trial to evaluate the effect of the prophylactic administration of entecavir on the frequency of HBV reactivation in HBc antibody positive patients. In their report, unlike in retrospective analyses, the prophylactic administration of entecavir was the most important factor, at least for HBc antibody positive patients. Furthermore, Seto et al recently reported frequent reactivation of HBV in patients with 10 mIU/mL HBs antibody prior to rituximab treatment. In HBc antibody positive patients, prophylactic treatment is necessary, at least for those who are antibody negative prior to rituximab treatment . We believe that the prophylactic administration of a nucleic acid analog is preferable in HBc antibody positive/HBs antigen negative/HBs antibody negative cases.

What Does The Test Result Mean

The tests for hepatitis B may be ordered individually but are often ordered in some combination, depending on the reason for testing. Results of the tests are typically evaluated together. Sometimes the meaning of one result depends on the result of another test. However, not all tests are performed for all people.

The table below summarizes possible interpretations of some common patterns of results.

Initial Tests
None detected or detected at very low level Chronic infection but low risk of liver damage carrier state

*Note: There are some types of HBV that do not make e-antigen. In areas where these strains of HBV are common , testing for HBeAg is not very useful. In these cases, a negative HbeAg result does not necessarily mean that the person is not infectious it may be that the person is infected with a strain that does not make the e-antigen.

Monitoring treatment of chronic infection: If the results from initial and follow-up testing indicate that a person has chronic hepatitis B, then the individual may be treated with medication and the effectiveness of that treatment may be monitored using the tests for HBe and HBs antigen and antibody and HBV DNA:

What Does A Reactive Result To A Hepatitis B Test Mean

Sign And Symptoms Of Hepatitis B

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.

  • Sharing needles for intravenous, or IV, drug use

  • Working in a healthcare center where you are exposed to blood

  • Getting a blood transfusion or organ transplant. This is less common with active screening.

The normal values of an antibody titer depend on the type of antibody. If the testing is done to detect autoantibodies, the normal value should essentially be zero or negative. In the case of testing the efficacy of a vaccine, the normal test result depends on the definite value that is specific for that immunization.

What does it mean if your anti HBs test is negative?

However, the fact that the negative Anti-HBS result does not mean that the person is not suffering from hepatitis B and is not affected by infection. In order to understand this condition, the level of HBsAg known as Hepatitis B surface antigen test should be checked.

What doeshbsag non-reactivemean for hepatitis B?
