A broader STI screen combining blood, swab and urine testing to cover 14 infections, including HIV, hepatitis B and C, and syphilis.
14 biomarkers as listed by Randox Health.
This screen combines three sample types to cover 14 infections in total: a blood sample for hepatitis B, hepatitis C, HIV and syphilis; swabs for chlamydia and gonorrhoea; and a urine sample for chlamydia, gonorrhoea, both herpes simplex strains, mycoplasma genitalium, mycoplasma hominis, trichomonas vaginalis and ureaplasma urealyticum. The provider recommends taking swabs from all areas exposed to sexual activity, since urine alone will not catch every infection, and advises waiting until the incubation period has passed before testing to avoid inaccurate results.
Across its comparison group of full STI screens, this test tests more infections (14) than the group median (12), while costing 54% less than the £495 median price. LetsGetChecked's Complete 11 is cheaper still, at £199, though it tests one fewer infection. Every Better2Know screen in the group, ranging from £299 to £550, tests fewer or an equal number of infections for a higher price.
The scores reflect strong value and depth. Clinical depth scores the maximum, with 14 biomarkers against a group median of 12. Value for money is also maximum, roughly 54% below the group median. Collection convenience is moderate, since it needs a clinic visit for the blood, swab and urine samples, even though results return within 2 days. Results and follow-up scores lower because results are not reviewed by a doctor as standard.
This suits people who want broader coverage than a urine-only screen, including blood-borne infections such as HIV, hepatitis B and C, and syphilis, without paying Better2Know's higher prices for similar or narrower coverage. If a slightly cheaper option is more important than one extra infection, LetsGetChecked's Complete 11 is £199. If urine-detectable infections are your only concern, Randox's own STI Urine Screen covers 9 of them for £79.
You attend a Randox Health clinic for a venous blood draw, along with a swab and urine sample. The lab tests across all three sample types, and results are available within 2 days of the samples arriving, though they are not reviewed by a doctor as standard.
The Complete STI Screen combines a venous blood draw with swab and urine testing to cover 14 infections, including HIV, hepatitis B and C. At £227 it costs 54% less than the £495 median for its comparison group, and it tests more infections than every Better2Know screen in that group. Results are not reviewed by a doctor as standard.
