A blood, swab and urine panel screening for 11 infections including HIV, hepatitis B and C, syphilis, chlamydia, gonorrhoea, herpes and HPV. Suits people who want a broad in-clinic sexual health check rather than a home test.
11 biomarkers as listed by Better2Know.
The Conclusive Screen checks for 11 sexually transmitted infections from a combination of a blood draw, an oral swab and a urine sample: HIV (including the early p24 antigen marker), hepatitis B and C, syphilis, chlamydia, gonorrhoea, herpes types 1 and 2, HPV, mycoplasma and ureaplasma. Testing several infections in one visit is useful because many STIs share similar symptoms or, particularly with chlamydia and mycoplasma, can be present without symptoms at all.
At £495 it sits exactly at the median price for the ten comparable full STI screens we track, which keeps its value for money score in the middle of the pack. Its own biomarker count of 11 is slightly below the group median of 12, and Better2Know's own Platinum Screen tests for 12 markers at the same £495 price. Cheaper options exist too: LetsGetChecked's Complete 11 covers 10 infections for £199, and Randox Health's Complete STI Screen covers 14 for £227, both well under half this price.
The listing itself scores well for clarity, with a full biomarker breakdown, stated turnaround and clear collection details published up front. It scores lower for collection convenience because it requires a venous blood draw at a clinic rather than offering a home-testing route, and lower again for results and follow-up because, as with Better2Know's other tests, results are not doctor-reviewed as standard.
This suits you if you want a broad, single-visit STI check covering 11 infections and are comfortable attending a Better2Know clinic for a blood draw, swab and urine sample, with results back in about five days. Better2Know's own product description recommends it particularly for gay and bisexual men, though it is listed as suitable for anyone.
If price matters most, LetsGetChecked's Complete 11 (£199, 10 infections) or Randox Health's Complete STI Screen (£227, 14 infections) cover similar ground for a fraction of the cost, and Randox tests for three more infections. If you want the same panel from Better2Know without paying more than necessary, its own Platinum Screen costs the same £495 but includes one extra marker.
Samples are taken at a Better2Know clinic: a blood sample from your arm plus a self-collected oral swab and urine sample, following the clinic's own collection instructions. Samples are sent to Better2Know's laboratory the same day, and results are uploaded to your online patient account within about 5 working days, with SMS or email notification. The fact sheet does not state that results are doctor-reviewed as standard; if you test positive, Better2Know says it will arrange follow-up consultations.
The Conclusive Screen tests for 11 infections at a Better2Know clinic for £495, level with the median price across similar full STI screens we track. Within Better2Know's own range it lines up with the 12-marker Platinum Screen at the same price, so you get one fewer marker for the same money. There is no home-testing option and results are not doctor-reviewed as standard.
