Hepatitis B Antigen (HBsAg) Blood Test

This blood test checks for the presence of the hepatitis B antigen, a protein of the virus. A positive result for the antigens means you are currently infected with hepatitis B and are infectious. Hepatitis B can cause serious liver damage, and is transmitted through unprotected sex, sharing needles or from any situation where you come into contact with bodily fluids from an infected person. Mothers can also pass it to their babies.

If you book one individual blood test we will charge a £30.00 blood draw fee in addition to the listed price. If you call your local clinic and book two or more blood tests, you will not be charged this additional fee.

Why HBsAg?

Common reasons for this blood test are:

  • You’ve been into contact with an infected person, and want to check whether you’ve contracted hepatitis B
  • You’ve recently travelled to a country where hepatitis B is common and want to check for infection
  • To check your sexual health status to ensure you do not transmit the infection to anyone else.

Your blood test

Our phlebotomy-trained professionals will take a blood sample from you. This sample will be analysed in the UK by our authorised partners, TDL. By booking this blood test, you agree for us to share your personal information with TDL in order to process your test. We’ll make sure you consent to this at your appointment too.

Ultrasound Direct will not review or interpret your private blood test results - we recommend you discuss your results with your preferred healthcare provider.

Preparing for your private blood test appointment

  • Hydrate

    -Drink plenty of water in the 24 hours before your blood test. This will make the blood draw easier.

  • Make sure the blood draw area is easily accessible 
    -Wear loose clothing that allows easy access to both arms and hands.

  • If you are on anticoagulant medication, take it after the appointment.

    -If this is not possible, you can take it before your appointment, if it is absolutely essential.

    Let our clinic team know if you are nervous about needles. They will make sure you’re calm and comfortable and do everything they can to make your blood draw quick and simple.

Frequently Asked Questions

No, we will send you the results and recommend that you share these with your GP or fertility provider.

It is not unusual for some bleeding to occur under the skin following your blood test and sometimes this can extend a little further around the puncture site.  If this causes you concern, check with your practice nurse. 

Sometimes we cannot get a blood sample from you. This can be for many reasons, such as not being hydrated enough, feeling cold or having another blood test recently. We will always offer you another appointment so we can try again.
