About this test

This kit checks whether you are immune to Hepatitis B, meaning a vaccination course or a past infection has left you protected. Better2Know's own description recommends it for people in contact with blood or bodily fluids at work, such as healthcare staff or food service workers, and for anyone who has recently completed a vaccination course or booster.

Against the rest of the Hepatitis B comparison group, £70 is below the £79.25 median, though it costs more than LloydsPharmacy Online Doctor's £43 equivalent and Blue Horizon Medicals' antibody tests, which run from £45.25. It matches the price of Better2Know's own Hepatitis B sAg Home Test Kit.

It scores well for collection convenience, since the whole process can be done at home, and for clarity, as Better2Know sets out symptoms, timing and the booking process in detail. It loses marks on results and follow-up, because results are not doctor-reviewed as standard.

Who is it for?

This suits people who want to confirm their Hepatitis B immunity without attending a clinic, for example after finishing a vaccination course, or those in roles that involve regular contact with blood or bodily fluids. If price is the main factor, LloydsPharmacy Online Doctor's £43 Hepatitis B immunity test and Blue Horizon Medicals' antibody tests from £45.25 are cheaper options in the same comparison group.

How it works

You collect a blood sample at home using the finger-prick kit provided, then post it to the lab using the pre-paid envelope included; kits ordered before 4pm on a weekday are dispatched the same day by first-class post. Results are reported within 1 day of the sample reaching the lab and are viewed in Better2Know's online patient area, with notification by SMS or email. Results are not doctor-reviewed as standard, though Better2Know says it can arrange a follow-up consultation to discuss them.
