Your annual checkup looks for disease. Signal looks for the decade before it: the cardiovascular, metabolic and genetic signals that standard tests skip. We come to your home, draw your blood in fifteen minutes, run it in our own lab, and a doctor reviews every result before it reaches your private dashboard.
Atlantic Seaboard · City Bowl · Southern Suburbs · results in days, not weeks
No referral, no queue, no pathology waiting room. You book a window, we handle the rest.
A registered nurse visits your home or office at the time you choose. A gentle draw and a cheek swab, and you're done in fifteen minutes, before the coffee is cold.
Your sample travels by monitored cold chain to Signal's own laboratory. Nothing is sent to a third party: our analyzers, our sequencer, our quality control, every time.
Every report is reviewed and released by a registered doctor, then lands in your private dashboard: plain language, optimal ranges, and exactly what to do next.
Every panel includes the home visit, our own lab processing, doctor review, and your results dashboard. No hidden extras.
Standard pathology flags you when something is already wrong. Signal reads the same blood for what it says about the next twenty years: the difference between a result that says "fine" and one that says "here is what to change now".
Your dashboard turns 45+ biomarkers and your genetics into one picture: a Signal Score you can track, each marker on a simple optimal-to-attention scale, and a short list of actions your reviewing doctor stands behind.
Retest quarterly and watch the score move. That's the point: not a snapshot, a trajectory.
One blood draw every quarter, at your home, tracking the markers that move: metabolic, cardiovascular and inflammatory signals. Watch your Signal Score respond to what you change, with member pricing on every panel and priority booking. Like the noon gun, it works because it's regular.
No. Signal is a wellness and prevention service. Every report is reviewed and released by a registered doctor, and anything that needs clinical follow-up is flagged to you directly, with a referral where appropriate. Signal complements your GP; it doesn't replace them.
To our own laboratory in Cape Town. We run our own analyzers and our own DNA sequencer, with daily quality control. Your sample is never sent to a third-party lab, and your results never pass through anyone else's system.
It stays yours. Your genetic data is stored encrypted, processed under South Africa's POPIA privacy law with your explicit consent, never sold, and never shared. You can request deletion at any time.
Yes, for the most accurate metabolic markers we ask for a 10 to 12 hour fast. Water and black coffee are fine. Most clients book a morning visit and eat breakfast the moment we leave.
The Atlantic Seaboard, City Bowl and Southern Suburbs, with corporate visits across greater Cape Town. If you're outside these areas, get in touch and we'll see what we can do.
Blood panels are typically reviewed and released within a few days of your draw. Genetic panels take longer because sequencing and doctor review take time: expect about two weeks for DNA Blueprint and three to four for Whole Genome.
Yes. Signal runs executive testing days: we set up at your office and screen your team back to back, each person getting the same doctor-reviewed report. It's the single most popular way companies discover us. Ask about corporate days when you get in touch.
Tell us where you are and when suits you. We'll confirm your window on WhatsApp and a Signal nurse will be at your door.
Weekday mornings fill first. Fasting visits from 06:30.
