Every hour of delay after a potential exposure is an hour of anxiety — and an hour in which a treatable infection can deepen. We engineered a solution to the time problem.
Speed is the First Treatment
The traditional medical model is slow by design. You travel to a clinic, you wait in a lobby, you provide a sample, and then the sample waits. It waits for a batch. It waits for a courier. It waits for the lab tech's shift to start. This latency is where anxiety breeds — and where infections go undetected.
Standard clinics in Bangkok advertise "same-day" results that routinely arrive in 24-48 hours. Large hospitals like Bumrungrad can take 2–5 days for a full STI panel. We inverted this model entirely.
Clinical Insight
The 72-Hour Window: For post-exposure interventions like DoxyPEP, every hour within the 72-hour window matters. A test result that arrives on day 3 is medically useless for this critical decision. A result in 4 hours is actionable.
The Rider Grid
Bangkok is a complex organism. Traffic patterns shift by the minute. Our "Rider Grid" is not just a delivery service — it is an algorithmic dispatch system.
When you book a test, our system identifies the nearest rider carrying a sterile cold-chain kit and routes them to your location. These are not food delivery drivers. They are trained medical couriers, vetted for privacy protocols and bio-hazard handling. They move anonymously through the city — indistinguishable from regular traffic, but carrying critical diagnostic payload.
Grid Coverage by Zone
Highest density in Sukhumvit, Silom, Sathorn, and Thonglor. Extended coverage available with advance booking.
Cold Chain Integrity
PCR samples are delicate. RNA degrades with heat. In a tropical city like Bangkok — where ambient temperatures routinely exceed 35°C — a sample left in an uncontrolled environment is a ruined test result.
The Specimen Vault
- ✓ Active cooling maintains 2–8°C for up to 12 hours — the clinical gold standard for PCR preservation.
- ✓ Shock-absorbent foam core protects tubes against road vibration and sudden stops.
- ✓ Digital temperature logging on every collection — a timestamp audit trail for quality assurance.
- ✓ All containers meet ISO 6710 standards and Thai FDA transport regulations for diagnostic specimens.
The Tech Stack Behind the Speed
Behind each physical rider is a digital brain. Our dispatch engine calculates routes in real-time, factoring live traffic data from BMTA sensors, rider GPS positions, and lab capacity status — all in a single orchestration loop.
Once your sample reaches the partner lab, it is immediately prioritized. There is no batching, no waiting in a queue. Every Express sample triggers a "single-piece flow" — a manufacturing principle borrowed from Toyota's production system — meaning your sample is processed as a standalone priority job from the moment it arrives.
"The fastest result is a negative result, delivered before your anxiety has time to compound. We built every step of this system around that principle."

CTM vs. The Alternatives
How does our end-to-end flow compare to the standard options in Bangkok?
| Provider | Time to Results | Friction | Privacy |
|---|---|---|---|
| Hospital (Bumrungrad) | 2–5 Days | ID, forms, long waits, upselling | Low — name in system |
| Pulse Clinic | Same-day (฿17,350) | Passport required, high price | Moderate |
| MedEx / Standard Clinic | 1–24 Hours | ID at lab, call-centre coordination | Moderate |
| CheckThatMate Express | 4 Hours | WhatsApp → Done. Zero forms. | Maximum — code only, no ID |
Worry → Certainty in 4 Hours.
Book your Express sample collection. A rider will be at your door in under 38 minutes. Your results arrive via encrypted PDF — before Bangkok's traffic even clears.
