Whats The Procedure For A Hepatitis B Titer Test
A hepatitis titer test requires a healthcare professional to draw a small amount of blood for testing.
No special preparation is needed beforehand. If needles or the sight of blood make you anxious, you may want to arrange a drive ahead of time in case you feel faint.
Heres what will typically happen during this test:
Home tests that require a fingerpick are also available. The results of your tests are generally available within 3 days.
About Our Hepatitis B Immunity Status Test
This blood test is used to confirm immunity against the hepatitis B virus by detecting the presence of surface antigens, surface antibodies, and core antibodies specific to HBV .
Hepatitis B is a sexually transmitted disease caused by the double-shelled hepatitis B virus. It is preventable through vaccination.
An individual develops hepatitis B surface antibodies from a successful vaccination or if they have had hepatitis B and recovered from the infection. The hepatitis B vaccine stimulates the body to make these antibodies to protect against the virus. If an individual has been infected but cleared the virus, the surface antibodies they developed protect against the virus for life, preventing reinfection. The hepatitis B surface antibody is detectable after clearing the virus.
The presence of hepatitis B core antibody can indicate a past or present HBV infection. People vaccinated for hepatitis B will not have the core antibody in their blood.
When And How To Perform Post
Which test to use: If testing is needed following vaccination, use quantitated HBsAb only
- Post-vaccination testing is needed for certain groups who are at especially high risk for HBV infection
- The purpose of post-vaccination testing is to confirm if patients have achieved adequate immune response as measured by hepatitis B surface antibody
- Perform testing 1-2 months after final dose of the HBV vaccine series
- Persons with HBsAb concentrations of > 10 mIU/ml are considered immune
- Post-vaccination testing is recommended for some patients:
- Infants born to HBsAg+ women
- Infants born to women whose HBSAg status remains unknown
- Health care personnel and public safety workers at risk for blood or body fluid exposure
- Hemodialysis patients
- Other immunocompromised persons such as hematopoietic stem-cell transplant patients or persons receiving chemotherapy
- Sex partners of HBSAg+ persons

What Do Hepatitis B Test Results Mean
Hepatitis B test results help determine if HBV infection is negative or positive, and if positive, whether the infection is acute or chronic, or if recovery is complete. A combination of results are considered to identify and classify HBV infection status.
The following are some interpretations of hepatitis B test results:

Who Is At Risk For Hepatitis B
Anyone can contract hepatitis B. However, certain groups are at greater risk. According to the CDC, the following groups are at highest risk for contracting hepatitis B:
- Infants born to infected mothers
- People who inject drugs or share needles
- Sexual partners of people infected with hepatitis B
- Men who have sex with men
- People living in close proximity to a person with hepatitis B
- Health care workers or others exposed to blood in their work environments
- Hemodialysis patients

What Are The Symptoms Of Hepatitis B
Not all individuals infected with acute hepatitis B will experience symptoms. In fact, the CDC estimates that only about 30-50% of infected people age 5 and older will have symptoms. When symptoms are present, they will develop about 3 months after exposure and will include the following:
Individuals with chronic hepatitis B will generally not have any symptoms. When symptoms are present, they are generally very similar to the symptoms of acute hepatitis B. Given the serious nature of hepatitis B and the effects it can have on your liver and overall health, it is important to talk to your doctor about hepatitis B if you believe you may have been exposed to the disease.
Initial Hepatitis B Testing
Additional hepatitis B tests help doctors monitor the disease, direct treatment, and determine if you are contagious. Interpreting the results of these additional hepatitis B tests is complex and often interpreted alongside other tests, so itâs important to work with a doctor or specialist to understand what results mean for your health.
You may find it helpful to ask questions about your hepatitis B test results. Questions that may be helpful include:
- What was my test result?
- Do I have an acute or chronic hepatitis B infection?
- Does the test result suggest that I have immunity for hepatitis B?
- Would I benefit from hepatitis B vaccination?
- Do I need any follow-up tests based on my hepatitis B test results?

What Do My Test Results Mean
Test results may vary depending on your age, gender, health history, and other things. Your test results may be different depending on the lab used. They may not mean you have a problem. Ask your healthcare provider what your test results mean for you.
Normal results are negative or nonreactive, meaning that no hepatitis B core IgM antibodies were found.
If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases, this means that you will recover within 6 months. If you recover, you will have immunity from the virus and will not be able to pass the virus to others. If you don’t recover in 6 months, the virus may stay in your blood, cause liver problems, and can infect others. Your healthcare provider may give you medicines if you don’t recover after 6 months.
Hepatitis B Blood Tests
The Hepatitis B Panel of Blood Tests
Only one sample of blood is needed for a hepatitis B blood test, but the Hepatitis B Panel includes three parts. All three test results are needed to fully understand whether a person is infected or not. Below is an explanation of the 3-part Hepatitis B Panel of blood test results.

Addressing Hepatitis For The First Time
It is crucial that a treatment counselor or health professional use a nonjudgmental and compassionate tone. Clients need to feel comfortable disclosing information about their health and risky behaviors. The following strategies can help initiate the conversation:
- Display posters, literature, or other -related items that could help prompt the client to ask questions about hepatitis. .
- Assess clients ability to discuss , based on their degree of openness in the counseling session, the amount of detail they provide in their responses, and the length of the therapeutic relationship.
- Raise the subject in a way that avoids making clients feel defensive or afraid. Consider introducing the subject by making parallels with other conditions that have been discussed. Say, for example, You said you were tested for HIV several times. Were you ever tested for viral ? or You mentioned that your friend is sick with HIV. Have you been tested for HCV or HIV? Tell me about those tests.
- Be patient and allow time for multiple, short conversations about the subject. This might ease feelings of fear, anxiety, or shame.

Transmission Symptoms And Treatment
How is HBV transmitted?
HBV is transmitted through activities that involve percutaneous or mucosal contact with infectious blood or body fluids , including
- sex with a partner who has HBV infection
- injection drug use that involves sharing needles, syringes, or drug-preparation equipment
- birth to a person who has HBV infection
- contact with blood from or open sores on a person who has HBV infection
- exposures to needle sticks or sharp instruments and
- sharing certain items with a person who has HBV infection that can break the skin or mucous membranes , potentially resulting in exposure to blood.
How long does HBV survive outside the body?
HBV can survive outside the body and remains infectious for at least 7 days .
What should be used to clean environmental surfaces potentially contaminated with HBV?
Any blood spills should be disinfected using a 1:10 dilution of one part household bleach to 9 parts water. Gloves should be worn when cleaning up any blood spills.
Who is at risk for HBV infection?
The following populations are at increased risk for becoming infected with HBV:
- Infants born to people with HBV infection
- Sex partners of people with HBV infection
- Men who have sex with men
- People who inject drugs
- Household contacts or sexual partners of known people with chronic HBV infection
- Health care and public safety workers at risk for occupational exposure to blood or blood-contaminated body fluids
- Patients on hemodialysis
Who should be screened for HBV?
Can I Take The Test At Home
Samples for hepatitis B testing can be collected at home. At-home hepatitis B testing requires you to collect a blood sample, typically from a fingerstick using a very small needle provided in the test kit. Once a blood sample is collected, it is prepared according to the instructions contained in the test kit and mailed to a laboratory for testing.
Because there are numerous types of tests for HBV, it is important to look closely at the specific components of any at-home test kit. Many at-home test kits only look for HBsAg.
You can order a test through our shop page quickly and easily with local lab testing and results in one to three business days.

Question 7 Is Hepatitis B Surface Antibody Antibody Always Acquired After A Completed Vaccination Protocol
No. After 3 intramuscular doses of vaccine, > 90% of healthy adults and > 95% of those < 19 years of age develop immunity .1 However, there is an age-specific decline in development of immunity. After age 40 years, about 90% of people become immune, but by age 60 years, only 75% of people become immune.1 Larger vaccine doses or an increased number of doses are required to induce immunity in many hemodialysis patients and in other immunocompromised people.1

Transmission Of Hepatitis B
The hepatitis B virus is transmitted through blood and sexual fluids. This can most commonly occur in the following ways:
Direct contact with infected blood
From an infected pregnant person to their newborn during pregnancy and childbirth
Needles and other medical/dental equipments or procedures that are contaminated or not sterile
Use of illegal or street drugs
Body piercing, tattooing, acupuncture and even nail salons are other potential routes of infection unless sterile needles and equipment are used. In addition, sharing sharp instruments such as razors, toothbrushes, nail clippers, earrings and body jewelry can be a source of infection.
Hepatitis B is NOT transmitted casually. It cannot be spread through toilet seats, doorknobs, sneezing, coughing, hugging or eating meals with someone who is infected with hepatitis B.

Whats The Hepatitis B Titer Test Used For
A hepatitis B titer test measures antibodies in your blood to see if youre immune either due to vaccination or previous infection.
Hepatitis B is a viral infection that targets your liver. It can be transmitted by coming into contact with the bodily fluids of an infected person. A person with the virus can also infect their child during birth.
Hepatitis B can develop into a chronic infection. Chronic infection occurs when your body cant fight off the virus within six months. Chronic hepatitis B infections most commonly develop less than six years old, especially in infants.
Hepatitis B titer tests can be used to evaluate:
- whether a high-risk person is immune to hepatitis B
- whether hepatitis B immunoglobulin is needed after a needle prick
- men who have sex with men
- people born in countries with a hepatitis B prevalence greater than 2 percent
- people born in the United States not vaccinated as children and with parents born in regions with more than 8 percent hepatitis B prevalence
You may need your titer test results as proof of hepatitis B immunity in order to get into healthcare programs at many schools for example, the nursing program at Lone Star College. In the United States, employers are not allowed to withdraw a job offer if they learn you have hepatitis B.

Question 2 What Is The Hepatitis B Surface Antibody
The hepatitis B surface antibody is the antibody that is produced in response to hepatitis B surface antigen , a protein present on the surface of the hepatitis B virus. Anti-HBs appears after convalescence from acute infection and lasts for many years. It can also be produced in response to hepatitis B vaccination.
Other hepatitis B antibodies are not produced in response to vaccination. This is because these antigens are not in the vaccine.
How Much Does A Hepatitis B Titer Test Cost
The cost of a hepatitis B test varies based on where you get the test. Prices range from roughly $24 to $110.
Your insurance may cover some or all of the cost. Under the Affordable Care Act, all new health plans must cover preventative services including hepatitis B vaccination and testing without a deductible or copay.

How Do Doctors Test For Hepatitis B Immunity
Doctors may order a panel of blood tests to check if someone has HBV:
- Hepatitis B surface antigen : This test looks for the presence of HBV in the blood by looking for antigens found on the virus. A positive result means that a person has HBV.
- Hepatitis B surface antibody : This test can show if a person is immune and protected against HBV. A positive result indicates that the person has overcome a past HBV infection or it is the result of receiving the hepatitis B vaccine.
- Hepatitis B core antibody : This test looks for another antibody in the HBV, but this one does not provide protection. A positive result indicates that a person had a past infection or currently has HBV.
Some people with certain risk factors for hepatitis B infection, such as those who inject drugs, pregnant people, and other populations, may require testing postvaccination to check their immunity.
Does Hepatitis B Show Up In Routine Blood Tests
Routine blood tests do not detect hepatitis B virus infection. Hepatitis B tests are specifically done if blood tests show abnormal liver function results, or if a person experiences symptoms or falls into the high-risk category for HBV infection.
A panel of HBV-specific blood tests are required to detect HBV infection.
