A small device worn on the wrist or kept in a pocket has an astonishing ability to know a lot about you. It records, for example, the distance you walked along Sea Point promenade this morning, your resting heart rate, the quality of sleep before an early meeting, and how long it took to climb Lion's Head compared to last summer.
We have never measured ourselves so in detail. However, most of us cannot name our cholesterol, blood sugar, or iron levels. If asked when we last had blood tests, the usual answer is a pause, followed by a guess like 'I think it's been a while.'
There is a valid reason for this gap. The metrics tracked by a watch are those you can feel. You know when you slept poorly, and you feel pain when getting up. Metrics in your blood are different. Levels of cholesterol, glucose, iron, thyroid, and vitamins do not send notifications when they change. They change slowly over months and years, while you feel perfectly fine. You cannot feel a metric increasing; you can only measure it.
This is why the phrase 'I feel fine' becomes such a convincing reason not to get tested. This is good news to be happy about. But it is not the same as knowing. When people do get tested, it often happens once, in a rush, either before an event or after a stressful incident. Such a test provides only a snapshot: where you were on a particular morning.
A snapshot does not allow you to understand the direction of movement. Could a high reading be because it has always been high, or because it has been gradually increasing? Is it stable or decreasing? Two measurements form a line. If you take tests now and then again in six months, you start to see a direction, which is much more useful than a single result. This also turns testing into feedback. If you changed your diet, started training for the Cape Town marathon, or finally cut down on late nights, six months is enough time for many of these changes to show up. You can see if your effort yields any result.
Over several years, these results become your personal story. You can compare yourself to yourself, not just to the general population range. Most people who don't get checked aren't careless; they are simply busy. The standard process requires a referral, a phone call, a morning in line, and a results form full of incomprehensible abbreviations that no one explains. Every step is minor, but together they can postpone good intentions to next month, and then to the month after.
People who care about everyone else often care less about themselves. This is the one who writes down all family visits except their own. This is the one who manages the calendar but never finds free time for themselves.
Signal Health was created to eliminate all these obstacles, leaving the decision to learn information as the only choice. A nurse comes to your home or office on a weekday morning. It takes about fifteen minutes, wherever you are comfortable. Your sample is sent to a partner pathology lab in Cape Town, and a registered doctor reviews every result before you see it. You receive a report in plain language, with a 'Signal Score' and several clear recommendations.
Membership includes two visits per year. The first is a full panel of tests: heart and cholesterol, blood sugar level, inflammation, hormones, thyroid, complete blood count, liver, kidneys, iron, and vitamins. The second visit is scheduled for six months later so you can track your line, not just a point. Signal Health is a wellness service that complements your therapist's work. It does not diagnose or treat, nor does it replace medical care. It provides you with information calmly and on your terms, so that any conversation with your doctor starts with real numbers in front of you.
Nurses currently visit areas in Atlantic Seaboard, City Bowl, Southern and Northern suburbs, Blouberg, West Coast, Somerset West, and Vineyards. The annual Signal subscription costs 7,995 South African Rand, payable in a lump sum, or 695 Rand per month for the first 100 participants, with the price fixed for the first year. The company can offer the Signal annual subscription to its partners and top clients at the end of the current year instead of gifts. In this case, the company pays a one-time 7,495 Rand per person when ordering five or more on one invoice, and Signal handles all the organization confidentially for each person. Results never belong to the company. More information can be found at signalhealth.me.
