A single-marker blood test for hepatitis B, giving a same-day result at the clinic, for anyone who wants a quick check of this one infection.
1 biomarker as listed by Better2Know.
This test looks for hepatitis B alone, using a blood sample usually taken by finger prick. It sits in our hepatitis B comparison group alongside seven other single-marker hepatitis B tests, so as a single-infection check it is measuring exactly what it sets out to; depth is not really the point of this kind of test.
At £185, it is the most expensive test in its comparison group by some margin. The cheapest options are LloydsPharmacy's hepatitis B immunity test at £43 and two Blue Horizon tests around £45, with Medichecks around £55 to £59. Better2Know's own postal Hepatitis B Immunity and Hepatitis B sAg home kits are each £70, meaning the instant clinic version costs £115 more for the same single marker.
The scores are consistent with this: clinical depth scores reasonably because a single marker fits the purpose of this test type, clarity is strong given the detailed listing, but value for money is weak given how far above the group median this sits. Results and follow-up score lower because a doctor does not review results as standard. Better2Know is CQC registered, holds a 4.2 Trustpilot score from 775 reviews, and has been trading since 2008.
This suits someone who wants a same-day, in-person hepatitis B result and does not mind paying for that speed. If price matters more, Better2Know's own Hepatitis B Immunity Home Test Kit and Hepatitis B sAg Home Test Kit each cost £70, and Medichecks and Blue Horizon offer postal single-marker hepatitis B tests from around £45, all considerably cheaper than this £185 instant version.
A small blood sample is taken, usually by finger prick, and applied to a test cassette at the clinic. Better2Know states results are available from around 20 minutes after the sample is taken, and you receive a signed results report on the day. If the result is reactive, the provider says a further confirmatory blood sample is taken and sent to the lab, included in the price, and a referral is arranged if that confirms positive, rather than every result going through a doctor review as standard.
Hepatitis B is the sole marker here, checked from a blood sample with a result given at the clinic the same day. At £185 it is more than double the group median of about £79 for comparable single-marker hepatitis B tests, and over £100 more than Better2Know's own postal Hepatitis B Immunity and sAg home kits, both £70. The trade-off is a same-day, in-person result rather than a cheaper postal test.
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.

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.
Home infection check, also available via clinic for £145
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.
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
A clinic blood test that checks whether you are immune to Hepatitis B, either from vaccination or a past infection. Suited to people needing to confirm their immunity status, including some at-risk professions.
Second-priciest test in the Hepatitis B range
A clinic blood test measuring Hepatitis B 'e' antibody. Better2Know does not publish further detail on this specific listing beyond the marker it tests for.
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.
