Hepatitis B is a viral infection that affects the liver.
The only way to know if you have hepatitis B is by getting a Hepatitis B Immunity Test. This blood test screens for Hepatitis B (HBV) antibodies present in your blood.
This determines if your immune system has successfully responded to the Hepatitis B vaccine or if you have been previously exposed to the virus and developed natural immunity.
Hepatitis B is caused by the hepatitis B virus (HBV). It is highly contagious and can spread through contact with infected blood, saliva, semen, or vaginal fluids. It can also be passed from a mother to her baby. Chronic hepatitis B can lead to serious health problems, including liver damage, liver cancer, and liver failure.
However, a blood test can help detect Hep B early and help prevent the development of severe liver disease. Vaccination against HBV is also available and is very effective in helping prevent infection.
Many people are asymptomatic. However, if symptoms occur, they may develop within 1 to 4 months after exposure. Some common Hepatitis B symptoms include:
Bear in mind, as of the latest estimates, approximately 108,000 individuals in London are currently living with chronic hepatitis B.
If you have had exposure to high-risk environments or professions (e.g., healthcare workers), or planning to travel to regions with a high prevalence of Hepatitis B (like China, India, and Africa), a Hepatitis B Immunity Test may be recommended. You may also be advised to get tested if you are concerned about past exposure.
Getting tested can help
Use our online booking engine or book your test by giving us a call.
On the online booking engine select the “appointment type” you need.
You will be seen by one of our friendly phlebotomists or trained clinicians.
There is no special preparation needed for the test (like fasting). However, if you are on any medications, particularly immunosuppressants or antiviral drugs, it is important to inform your healthcare provider. These types of medication may affect your test results.
The test involves a simple blood draw. The healthcare professional will clean the area where the needle will be inserted, typically on the inside of your elbow, and insert a small needle to collect the blood sample. The procedure is quick, typically taking only a few minutes.
Results typically take a few days to process. Your healthcare provider will inform you of the results. The test result will indicate whether you are immune to Hepatitis B. If you have sufficient antibodies, you are protected from the virus.
