ZIZ is a foundation (founded in 2022) offering non-profit STI care from walk-in clinics with their own laboratory. Test, result and treatment sit in one pathway — and one price.
Why ZIZ is structurally cheaper
- No profit motive: no margin is paid out to shareholders.
- An on-site lab cuts outsourcing costs.
- An online pre-consult shortens time with the clinician.
- The health insurer pays a fixed €32 contribution per consult, which falls outside your deductible.
Pricing
Chlamydia and gonorrhoea are always tested as a combination. The price depends on the number of test sites; treatment of a positive result is included.
- One site (urine/vaginal or throat or anus): €39.
- Two sites: €49. Three sites (urine + throat + anus): €65.
- Result within 30 minutes: +€15. Individual tests such as syphilis, HIV or hepatitis: €15 each.
Speed and method
ZIZ uses a lab PCR (NAAT) in its own accredited laboratory — not a lower-reliability rapid test. The standard result is available within 90 minutes, with a 30-minute express option for a surcharge.
Locations and home test
ZIZ has walk-in clinics in The Hague, Utrecht, Rotterdam and Amsterdam. You first do an online consult and then drop in without an appointment. There is also a home test: you mail self-collected samples to the lab.
The caveats
- Not anonymous: ZIZ is insured care and requires ID (BSN). Uninsured people can still use it by paying themselves.
- Limited number of locations and a maximum of four consults per person per year.
- HIV and hepatitis treatment is not done at ZIZ itself — referral follows for those.
- The ceftriaxone injection for gonorrhoea requires a clinic visit, a home visit (€50) or a nearby care provider arranged by ZIZ.
Who is ZIZ for?
ZIZ suits insured residents who want fast testing and treatment without a referral, and who fall outside the free GGD groups or find the GGD wait too long. Under 25? First check whether you qualify for free GGD testing.
