Order Guide: Hepatitis B
Your commonly answered questions about Hepatitis B.
Approximately 257 million people globally are positive for Hepatitis B. Having Hepatitis B carries a risk of cirrhosis and liver cancer with chronic infection. Most transmission occurs at the time of childbirth from mother to child through there are a number of risk factors for transmission. Hepatitis B vaccination provides effective protection against Hepatitis B infection.
Is Hepatitis B routinely recommended for STI testing?
We don’t routinely screen for hepatitis B as part of standard STI screening. Current Canadian guidelines recommend screening if you have not been vaccinated for Hepatitis B and have one or more of the following risk factors:
- Exposure to someone with Hepatitis B through blood and/or bodily fluids
- Engage in high-risk sexual activities (unprotected sex with multiple sexual partners)
- Substance use with sharing of equipment
- Use of shared or contaminated materials or equipment (i.e instruments/tools used for personal services procedures that have the potential to break the skin)
- Use of shared or contaminated medical devices (i.e. glucometers)
- Occupational exposure to blood/body fluids
- Travel to/residence in endemic regions
- Transfusion recipient/medical procedure in Canada before 1970
- Incarceration
- History of HIV or Hepatitis C
- Born in a country with a high risk of Hepatitis B infection
Who should not be screened for Hepatitis B?
- You are vaccinated and do not carry special risk status (see below)
- You have a history of Hepatitis B infection
When should I be checked?
- While there is no agreed-upon screening frequency, we recommend screening regularly in unvaccinated patients at least every 1-2 years with ongoing risk factor exposure.
Should I be screened if I am vaccinated against Hepatitis B? (Special Risk Status)
We recommend screening regardless of vaccination if you carry the following risk factors:
- Are from areas where there is an intermediate (2%) > or higher risk of prevalence - see Referenced Map
- Are currently pregnant
- Require immunosuppressive therapy
- Are a donor or plasma, semen, organs or tissue
- Born to a mother with Hepatitis B
If you are concerned about a new Hepatitis B exposure and are seeking post-exposure prophylaxis, we recommend going to an emergency room and not using TeleTest.
