About this test

This test detects Hepatitis B surface antigen, present during an active infection according to Better2Know's description, which also states a 28-day incubation period to wait after a possible exposure before testing. A clinician takes a blood sample during your appointment, which the provider says usually takes 10 to 15 minutes.

At £145, this sits well above the £79.25 median for our Hepatitis B comparison group, and above Better2Know's own £70 Hepatitis B sAg Home Test Kit, which the collection details suggest tests the same marker without a clinic visit. Blue Horizon Medicals' Hepatitis B Surface Antigen test, at £45.25, is considerably cheaper again.

It scores well for clarity, thanks to a detailed description of the incubation period and booking process, but poorly on price against its peer group. It also loses marks on results and follow-up, as results are not doctor-reviewed as standard.

Who is it for?

This suits people who would rather have a trained clinician collect the sample than use a home finger-prick kit, or who need a clinic appointment. If cost matters more than the collection method, Better2Know's own home kit tests for £70, and Blue Horizon Medicals offers a surface antigen test for £45.25.

How it works

You attend a clinic appointment, where a clinician takes a blood sample; Better2Know says appointments typically last 10 to 15 minutes. The sample is sent for testing, with results reported within 1 day of reaching the lab. Results are accessed through Better2Know's online patient area, with notification by SMS, phone call or email; results are self-interpreted unless you arrange a consultation, though one is arranged if you test positive.

Pros & cons

Pros

  • Clinic appointments are quick, typically 10 to 15 minutes according to the provider.
  • Results are reported within 1 day of the sample reaching the lab.
  • States the 28-day incubation window to wait before testing.
  • A consultation is arranged with a doctor if you test positive.

Cons

  • At £145, it costs more than double Better2Know's own £70 home kit for the same marker.
  • Results are self-interpreted unless you arrange a consultation.
  • Blue Horizon Medicals offers the same surface antigen marker for £45.25.

Our editorial score

Compare Health Test Score Same infection check, twice the price of the home kit
Editorial confidence: 9.5/10

Better2Know's clinic-based Hepatitis B Test checks for a current infection via the surface antigen marker, with results back within 1 day. At £145 it costs more than double Better2Know's own £70 home version of what appears to be the same check, and results are not doctor-reviewed as standard.

Score breakdown

  • Clarity and documentation 9.0/10

    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.

  • Clinical depth 7.5/10

    A single-marker test measuring exactly what it sets out to; depth is not the point of this comparison group.

  • Collection convenience 10.0/10

    A blood sample taken at home by a visiting nurse or phlebotomist; with a venous or clinic option as well; a home nurse visit is offered; results in around 1 days, well ahead of the sexual health norm of 2.

  • Results and follow-up 3.0/10

    Results are not doctor-reviewed and no consultation is included; the provider does not describe the report format.

  • Trust signals 6.5/10

    Trustpilot 4.2 from 775 reviews; CQC registered; trading 18+ years.

  • Value for money 2.0/10

    £145.00 against a comparison-group median of £79.25 (+83%).
