Under the agreement, Archipelago Health will offer the Nightingale Health Check in the Crown Dependencies, Bermuda and the Caribbean under its Longitude brand, and Nightingale Health will analyse the samples. The test will be available through two collection routes: a standard blood sample taken at GP practices and laboratories, and a finger-prick dried blood spot sample that can be collected in workplaces or remotely. From a single blood sample, the Nightingale Health Check produces a 10-year risk estimate for five chronic diseases: heart attack, ischemic stroke, type 2 diabetes, chronic kidney disease, and fatty liver disease.

Small-island jurisdictions carry a high burden of heart- and metabolism-related disease, yet they are often among the last to receive new health technology because they lack the scale to support new infrastructure. The agreement is built to work the other way round. Because the Nightingale Health Check is delivered through existing primary care using standard blood collection, it fits the care pathways islands already operate rather than requiring new ones. First live testing is planned for November 2026, with Jersey as the first jurisdiction.

"Small islands are usually the last places new health technology reaches, because we lack the scale to justify new infrastructure. This agreement turns that around: Longitude brings the Nightingale Health Check into the GP practices, laboratories and workplaces our islands already have, so people here get earlier risk detection without waiting years for it to arrive. We begin in Jersey in November," says Dr Jeff MacLeod, Founder of Archipelago Health.

"Moving from a letter of intent to a signed agreement within a few months says a lot about how ready these health systems are for prevention-led screening. Archipelago Health has designed the service to run through the primary care islands already have, which is exactly how risk detection should reach a population. We look forward to the first tests in Jersey in November," says Teemu Suna, CEO and Founder of Nightingale Health.

Archipelago Health will present the Longitude service at TEKEX Health Innovation Jersey on 24 September 2026, an event convened around the proposition that health is the next key industry for Jersey, bringing together founders, investors and government.
