An at-home finger-prick blood test for Hepatitis B surface antigen, used to check for a current Hepatitis B infection. Suited to people who may have been exposed and want to test after the stated incubation window.
1 biomarker as listed by Better2Know.
This test looks for Hepatitis B surface antigen, which Better2Know's description says is detectable during a Hepatitis B infection. The provider states a 28-day incubation period, recommending you wait at least that long after a sexual encounter, needle-stick injury or other incident of concern before testing.
In our Hepatitis B comparison group, £70 sits below the £79.25 median and matches the price of Better2Know's own Hepatitis B Immunity Home Test Kit, which checks a different thing, immunity rather than current infection. Blue Horizon Medicals' Hepatitis B Surface Antigen test, at £45.25, is a cheaper option for the same marker.
It scores well for collection convenience, since it can be done at home and a venous or clinic option is also offered, and for clarity, given the detail Better2Know provides on incubation periods and the booking process. It loses marks on results and follow-up because results are not doctor-reviewed as standard.
This suits people who are concerned about a possible Hepatitis B exposure through blood-to-blood contact and have waited the stated 28-day incubation period, and who would rather use a home kit than attend a clinic. If you specifically want a cheaper surface antigen test and are happy to attend a clinic, Blue Horizon Medicals offers the same marker for £45.25.
You take a finger-prick blood sample at home using the kit provided and post it back to the lab; a clinic appointment is also offered for £145 if you would rather have a professional take a venous sample. Results are reported within 1 day of the sample reaching the lab, accessed through Better2Know's online patient area, with notification by SMS, phone or email. Results are not doctor-reviewed as standard, though Better2Know says it will arrange a consultation if you test positive.
This at-home kit tests for Hepatitis B surface antigen, and Better2Know recommends waiting 28 days after a possible exposure before testing. At £70 it costs the same as Better2Know's home immunity kit and sits below the £79.25 group median, with a clinic version also available for £145.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
A single-marker test measuring exactly what it sets out to; depth is not the point of this comparison group.
A finger-prick sample you take at home; with a venous or clinic option as well; results in around 1 days, well ahead of the sexual health norm of 2.
Results are not doctor-reviewed and no consultation is included; the provider does not describe the report format.

Cheap, at-home Hepatitis B antigen test with fast results
This test checks for Hepatitis B Surface Antigen, which shows whether you have been infected with Hepatitis B within the past few weeks. It suits anyone wanting a fast, at-home check after a possible exposure.
Hepatitis B immunity check, pricier than LloydsPharmacy's
This test measures Hepatitis B Surface Antibody levels, used to check whether Hepatitis B vaccination has produced adequate immunity. It suits anyone who needs to confirm immune status, including for occupational health.
Below the group median, but not the cheapest antigen check
Checks for hepatitis B surface antigen, the marker used to detect a current infection, via a simple blood test. Suits anyone wanting to check for active hepatitis B after possible exposure.
Not the cheapest hepatitis B immunity check available
Checks for hepatitis B surface antibodies to confirm immunity from vaccination or past infection; it does not detect a current infection. Suits people who need proof of protection for work, travel or healthcare requirements.
Cheap single-marker Hepatitis B test, slower turnaround
This test looks for Hepatitis B Core Antibody IgM, a marker used to indicate a recent or current Hepatitis B infection. It suits anyone who has had a possible exposure and wants a single, focused marker checked.
Priciest Hepatitis B option in its comparison group
This test measures total Hepatitis B Core Antibody (IgG and IgM combined), helping distinguish a current infection from one that has resolved. It suits anyone wanting a fuller picture than a single IgM check gives.
Lowest-priced hepatitis B immunity check we track
A single-marker blood test that checks whether you have immunity to hepatitis B following vaccination, not a test for a current infection.
Below-average price for a Hepatitis B immunity check
An at-home finger-prick blood test that checks whether you are immune to Hepatitis B, either through vaccination or past infection. Suited to people who want to confirm their immunity without a clinic visit.
Same single marker as Medichecks' £55 test, priced at £189
Checks for hepatitis B surface antigen, the marker used to indicate current infection. It measures one biomarker despite the Profile name, so it suits situations calling for that specific antigen check rather than a broader panel.
Same infection check, twice the price of the home kit
A clinic blood test for Hepatitis B surface antigen, used to check for a current Hepatitis B infection following possible blood-to-blood exposure. Suited to people who would rather use a clinic than a home kit.
Priced well above every peer in its Hepatitis B group
A blood test for Hepatitis B core antibodies, showing whether you have ever had the infection, though not when you were exposed.
Most expensive test in its Hepatitis B comparison group
A single blood test checking for Hepatitis B core antibodies, which show whether you have ever been infected, without indicating when.
Immunity check, pricier than Better2Know's own home kit

Monitoring test for known Hepatitis B, not a first screen
A clinic blood test measuring the amount of Hepatitis B virus in the blood, used to monitor people with a known chronic Hepatitis B infection. Suited to those already diagnosed, rather than as a first check.
