What is in the hepatitis B self-test kit?

The test for hepatitis B uses a blood sample collected from a finger prick. The kit contains:

  • an alcohol swab to clean your finger
  • a small lancet to make a tiny cut in your fingertip
  • a sample tube
  • plasters.

If you’d like to test for any of the 6 most common infections, you can find out more about Fettle’s STI kits and customise your order.

Should I get tested?

We recommend testing for hepatitis B for the following groups:

  • men who have sex with men
  • people who are paying for sex or getting paid for sex
  • people who inject drugs
  • people who are born in a country with a high rate of hepatitis B (mainly countries in Africa, Asia and South America)
  • people who have had sex with someone born in a country with a high rate of hepatitis B
  • people who have had a sexual partner who was infected with hepatitis B.

You should seek immediate medical advice if you think you have been exposed to hepatitis B, or if you have any symptoms. It is possible to reduce the risk of infection with emergency treatment, but to be most effective it should be given in the first 48 hours after exposure.

What are the symptoms?

During the early stages of infection there may not be any symptoms. If symptoms do develop, this is usually within the first six months after infection. Those who do get symptoms may experience:

  • flu-like symptoms, such as high temperature, muscle aches and loss of appetite, feeling tired all the time
  • yellowing of the eyes and skin (jaundice)
  • abdominal pain
  • loss of appetite and weight loss
  • sickness and diarrhoea.

Some people clear the virus after this initial stage. However, some people do not clear the virus without treatment and so they will develop a long term infection called chronic hepatitis. This can cause damage to the liver (cirrhosis) and can lead to liver cancer.

It can take up to 12 weeks for hepatitis B to show up in tests

When should I get tested for hepatitis B?

It is best to wait 4 weeks after potential exposure to take a hepatitis B test, but in some cases it can take up to 6 months for the infection to show in results. Our clinicians can help advise you about this when you place an order with Fettle.

What is hepatitis B and how is it transmitted?

Hepatitis B is a virus that can infect and damage the liver. It is carried in the blood and bodily fluids. It is usually transmitted through blood to blood contact but can also be passed on through bodily fluids. This might be through sharing needles when injecting drugs, a cut in the skin that comes into contact with infected blood, use of unsterilised equipment when getting a tattoo or body piercing, or sharing razors or toothbrushes that are contaminated with infected blood or other bodily fluids.

It can be transmitted through sex, although this is rare and can be prevented by using a condom. However, it is 50 - 100 times more infectious than HIV.

How is hepatitis B treated?

Anyone with acute hepatitis B (the very early stages of infection) should be assessed by a doctor. You may not need any treatment for the infection itself, but may need some relief from the symptoms, such as pain relief.

If you have chronic hepatitis B, you will need to be seen by a specialist in liver disease may need to take medication to prevent liver damage and have regular tests. There are now very effective medications that can suppress the virus over many years.

Shall I tell my partner(s) I have hepatitis B?

If you are diagnosed with hepatitis B you should tell anyone who you may have had blood to blood contact with, or unprotected sex with, since you became infected. In some cases this may be hard to work out, so it is best to discuss the risks to others with a clinician. Any contacts may have the virus without knowing it, and could pass it on to others, so it is important for them to get tested.

If you have an STI, you should tell all of your current sexual partners and anyone else you've had sex with in the last 6 months

How to avoid hepatitis B

  • never share any drug-injecting equipment with other people (not just needles, but syringes, spoons and filters)
  • don’t get tattoos or piercings from unlicensed places
  • don’t share razors, toothbrushes or towels that might be contaminated with blood or other bodily fluids
  • use a condom, especially with a new partner, for anal and oral sex. You can order male and female condoms here.
  • hepatitis B vaccine is available from the NHS, and is recommended for people who are at risk of infection. This includes people who inject drugs, sex workers, men who have sex with men, and people whose partners or close family have the virus.

Does hepatitis B affect fertility?

Hepatitis B is unlikely to affect your fertility. If you have been trying to conceive by having regular sex for one year and have not become pregnant then you should speak to your GP. They will refer you and your partner for further tests if required.

Where can I get help with the blood sample test?

You’ll need to drop a very small amount of blood into the sample tube. You can watch the blood test instruction video or follow this link to see the instruction leaflet that comes with the kit.

Can my partner tell if I have Hepatitis B?

They will be able to tell if you have symptoms of infection but not if you don’t. However, it is important that you tell your partner since have passed the infection to them. Your partner(s) will need to be tested and may need treatment. They could develop serious symptoms if untreated, or could pass the infection onto someone else.

Where do I go to get a hepatitis A/B vaccine?

Your GP, a sexual health clinic or occupational health department (if your occupation puts you at risk of infection). Find your nearest sexual health clinic.

Are there any side effects from the hepatitis B vaccine?

Side effects are rare. Contact the person who gave you the vaccine at once if you have a serious side effect such as:

  • fever, sore throat, and headache with a severe blistering, peeling, and red skin rash
  • irritability
  • fast or pounding heartbeats
  • easy bruising or bleeding.

Less serious side effects include:

  • redness, pain, swelling, or a lump where the injection was given
  • headache, dizziness
  • low fever
  • joint pain, body aches
  • tired feeling
  • nausea, vomiting, stomach pain, constipation, diarrhoea.

Will the hepatitis B vaccine protect me for the rest of my life?

No, you will need to check your levels of immunity some years after vaccination. The health care professional who gives you the vaccine will advise you when your immunity levels need to be checked.

What is antiviral medication?

Antiviral medication usually acts to prevent a virus from multiplying.
