Product Description

If 4 weeks have passed since the risk contact, you can do the hepatitis B surface antibody and antigen test. This test is recommended when vaginal or anal sex has occurred and one is not immunised against hepatitis. This test looks for the answer of our body to the hepatitis B virus (surface antibodies) and a protein of this virus (surface antigen). The detection rate of this technique is around 99% and the figure of false positives is 1/3000 tests.

Service procedure:

  • Complete the purchase, then you will receive an order confirmation email and your patient identification number.
  • You will also receive a second email with the referral slip to perform the blood extraction at the selected laboratory.
  • Go to the laboratory with the referral slip and get the extraction done.
  • We will receive your samples in 24-72 business hours and we will run the tests straight away.
  • We will send you the results by email in 20 minutes.

Important notes:

  • Coming to Open House to get your blood extraction done avoids the transport period. Therefore, you could get your results in just 20 minutes.
  • If you are not immunised against hepatitis B, you can do it without costs at your regular medical centre or we can do it in Open House.
