This combined blood and urine test screens for seven sexually transmitted infections, including HIV, chlamydia, gonorrhoea, syphilis and hepatitis B. It suits people wanting broad STI coverage in a single visit.
7 biomarkers as listed by Better2Know.
The Full Screen tests for seven sexually transmitted infections in one combined blood and urine sample: HIV and the p24 antigen, chlamydia, gonorrhoea, syphilis, hepatitis B, mycoplasma and ureaplasma. These are markers commonly used to check for common STIs, including ones that can be present without symptoms.
Within its comparison group of 17 standard STI screens (covering 4 to 7 infections), this test's seven markers are above the group median of six, making it one of the broader screens available. Its £295 price is also the highest in the group, around 48% above the £199 median; cheaper options include LloydsPharmacy's 4-infection kit at £59.95 and Forth's 6-infection Full STI Home Test Kit at £129. Better2Know also offers a home kit version of this same Full Screen for £199, £96 less than the clinic version.
The clinical depth score is strong, reflecting the broad infection coverage for its comparison group. value for money is the weak point given the premium over group peers. Collection convenience is lower than some Better2Know tests because it needs both a blood and a urine sample at a clinic or nurse visit, with results taking up to three days. Results and follow-up is marked down because the test is not doctor-reviewed as standard.
This suits you if you want broad coverage of common STIs, including HIV, chlamydia, gonorrhoea, syphilis and hepatitis B, in a single clinic visit, for example if you are unsure which specific infections to test for. If price is the priority, Better2Know's own home kit version of this same Full Screen costs £96 less at £199, and its FAST TRACK Four Screen Home Test Kit covers four infections for £170. Speak to a GP or sexual health clinic if you have symptoms needing urgent attention.
You provide a venous blood sample and a urine sample, either at a Better2Know clinic or during a nurse visit. The samples are sent to the laboratory for analysis, with results typically available within three days, accessed through the online patient area; the provider does not state that a doctor reviews them as standard, though it says consultations are arranged if you test positive.
