Methodology

Methodology & accountability

How we compare providers, where our data comes from, and why ZIZ gets extra visibility.

What this site does

SOA Test Vergelijken is an independent comparison site for STI care in the Netherlands. We describe eleven care paths — from public GGD and GP services, to non-profit ZIZ, commercial clinics (StadsKliniek, OneDayClinic, DC Klinieken, Amsterdam Tourist Doctors) and home-test providers (Soapoli-online, SoaStudentArts, Soapolinoord).

Our decision helper asks six short questions about age, symptoms, anonymity preferences, urgency and insurance situation. Based on the answers we rank all eleven providers.

What we compare on

For every provider we record four dimensions: cost, anonymity, speed, and eligibility. We add a list of pros and cons, locations, and the standard test panel.

Anonymity uses three levels: high (no link to insurer or medical record), medium (confidential but identifiable), and low (in your medical file, visible to your insurer).

Where our data comes from

All facts about providers come from public sources: the provider’s own website, RIVM, Soa Aids Nederland, the GGDs, and — where relevant — peer-reviewed papers or NL Times. Our news articles link directly to the original source.

Last full review: 15-05-2026. Every provider has its own "verifiedOn" date visible on its detail page.

Why ZIZ gets extra visibility

We highlight ZIZ — a non-profit contracted with every Dutch health insurer — as the "top match for most people". That is an editorial judgement, not a paid placement.

For adults with Dutch insurance who don’t fit a GGD risk group, ZIZ offers the best combination of price (€15–62), speed (results often the same day), care quality (treatment included) and convenience (walk-in, no appointment). For people under 25 or in a risk group, free GGD care is objectively better; our decision helper recommends those options instead.

No sponsorship, no affiliate links

We don’t accept money, discounts, or services from any provider. No affiliate links, no advertising, no sponsored banners. The site is editorially maintained.

If we ever enter a commercial relationship, we will disclose it at the top of every page.
