Hepatitis B Blood Test

Hepatitis B is a contagious liver infection caused by the hepatitis B virus. It can be transmitted through sexual contact or contact with infected blood. If you have had unprotected sex or contact with blood and suspect you may have hepatitis B, it is wise to test yourself so appropriate treatment can be initiated and the spread of the virus can be minimized. This fingerprick test can be performed from home and provides laboratory-certified test results in days.

Test mode: Finger-prick

Window Period:
The window period is the time between when you were infected with an STI and when it is detectable with a test. See the ‘About this test’ section or the blog ‘When can you be tested for STIs? for more information about when you can reliably test for each STI.

What is hepatitis B?

Hepatitis B is a vaccine-preventable inflammation of the liver caused by infection with the hepatitis B virus. Transmission can take place from mother to child at birth, through sexual contact or contact with blood (RIVM, 2021). Hepatitis B is not spread through food or water, sharing eating utensils, breastfeeding, hugging, kissing, hand holding, coughing, or sneezing.

What is the window period for hepatitis B?

Every STI has a window period. This is the time between when an individual is infected and the moment that the STI is detectable with a test. The window period of hepatitis B is four weeks.

When should I consider taking a hepatitis B test?

If you are experiencing symptoms or have had unprotected sex, shared a toothbrush, or shared a needle with someone who has hepatitis B, you should get tested.

Additionally, many people with acute hepatitis B do not have any immediate symptoms. You may already have the virus and be contagious before experiencing any symptoms, or remain infected for an extended period without experiencing any symptoms at all. Individuals infected with hepatitis B remain contagious until the virus is cleared from their body, usually 4 to 8 weeks after onset. In some cases, acute hepatitis B will not be cleared by the body and progress to a chronic infection. This is why screening for hepatitis B as a part of routine STI screening is also recommended. Testing allows you to prevent further spread of the virus and access appropriate treatment if needed.

Frequently asked questions

Everything you need to know about the Hepatitis B Blood Test

Who is this hepatitis B test suitable for?

This hepatitis B test is suitable if you want certainty after unprotected sex, contact with blood or if you belong to a risk group. Even if you have no symptoms, testing can be useful, because hepatitis B often progresses for a long time without clear symptoms.

What is the difference between this hepatitis B test and other STI tests?

This test focuses exclusively on hepatitis B and is performed via a blood sample. Unlike urine or smear tests, this test is intended for infections that are detected via the blood. It is therefore a targeted test and not a complete STI screening.

What percent of the population has hepatitis B?

In the Netherlands, approximately 40,000 people have hepatitis B (Atlasinfectious diseases.nl, 2022). This concerns reports of acute hepatitis B, not chronic hepatitis B.

What can you do to prevent hepatitis B?

The most important thing you can do to prevent hepatitis B is to have sex with a condom. Furthermore, it is important to be careful with blood from other people. It is therefore best not to share razor blades, nail scissors, syringes, or toothbrushes. You can also get vaccinated against the virus. In the Netherlands this is recommended for people who are at increased risk (GGD Amsterdam, 2022).

Which people are at increased risk of hepatitis B?
  • People born in a country where hepatitis B is common.
  • Sex workers
  • Men who have sex with other men without being vaccinated against hepatitis B.
  • People who travel for more than three months in a country where hepatitis B is common.
  • Persons who have a profession where they often come into contact with needles or blood.
