At a glance

  • Sample: Blood
  • Collection: Self-collected sample using the supplied kit
  • Estimated turnaround: 1 day from laboratory receipt of a usable sample

What this test measures

Hepatitis B surface antibodies (anti-HBs)
Antibodies associated with immunity after vaccination or previous infection. A concentration above the laboratory threshold can support immunity, but it does not test for current hepatitis B infection.

How clinicians use this test

Clinicians use Hepatitis B surface antibodies (anti-HBs) to assess infection, previous exposure or immunity depending on the specific marker. Screening results may require confirmation and must be interpreted against exposure timing and vaccination history.

Is this the right test for you?

An adult seeking the stated hepatitis marker after considering exposure timing, vaccination history and the difference between screening for infection and checking immunity.

Preparation and collection

Return the sample on the same day it is collected. Do not post over weekends or bank holidays.

Understanding your result

Results are usually reported as detected, not detected, reactive or non-reactive rather than simply “normal”. A reactive or detected result may need confirmation or treatment; a non-detected result does not exclude exposure during the window period or infection at a site that was not sampled.

Your results and next steps

Review the marker-specific meaning carefully: immunity, previous exposure and current infection are different questions. Share a reactive, unexpected or unclear result with a clinician and complete any recommended confirmatory test.

Limitations

Testing during a window period can miss infection. A screening result may not distinguish current infection, previous exposure and immunity; use the specific result pathway stated above.

When to get medical help

Do not wait for a home-test result if you feel seriously unwell. Call 999 for a life-threatening emergency, or use NHS 111 when you need urgent advice and are unsure what to do.

Questions, answered

How accurate is an at-home test?

Are my results private?
Yes. Kits use discreet packaging and your results are delivered through a secure digital service.
Does this diagnose a condition?
No. The test checks and measures biomarkers. Results and the doctor’s comment can help you decide what to discuss with your GP.
When should I post my sample?
Collect and post on the same day, ideally Monday–Thursday, to avoid a sample waiting in the postal system over a weekend.
What happens if my sample cannot be processed?
The support team will explain the next step if the laboratory cannot process your sample. Any recollection or refund depends on the circumstances and the applicable policy.
When should I speak to my GP?
Speak to your GP if symptoms persist, worsen or concern you. Seek urgent medical help for severe or sudden symptoms.
