Nightingale Health Plc | Press Release | September 23, 2026 at 09:52:00 EEST
Nightingale Health and Archipelago Health have signed an agreement to bring the Nightingale Health Check, a single blood test that detects the risk of several major chronic diseases, to small-island healthcare systems across the Crown Dependencies, Bermuda and the wider Caribbean, following the letter of intent the companies announced on July 1, 2026. Archipelago Health will deliver the test under its Longitude brand through the primary care services islands already run, using a standard blood sample, so no new infrastructure is needed to start. First live testing is planned for November 2026, beginning in Jersey.
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.

About Nightingale Health
Chronic diseases cause around 75% of deaths globally and place a growing burden on healthcare systems. The way to address this is preventive healthcare, but until recently the tools to detect disease risks at population scale have not existed. Nightingale Health has built them. The Nightingale Health Check is a blood-based risk detection test that identifies risks for multiple chronic diseases, including cardiovascular disease, type 2 diabetes, kidney disease, and fatty liver disease, from a single blood sample. It is designed to be applied population-wide, so healthcare systems can identify the people who would benefit most from preventive action before disease develops.
Nightingale Health's technology is validated in over 1,000 peer-reviewed scientific publications and is used in many of the world's leading health studies, including the UK Biobank. In Finland, the Nightingale Health Check is in nationwide healthcare use, and over 250,000 people have already received their results. Nightingale Health operates globally with a parent company in Finland and subsidiaries in countries such as Japan, the United States, Singapore, and the United Kingdom, and has customers in more than 34 countries across healthcare and medical research. The company's Series B shares are listed on the Main Market of Nasdaq Helsinki and on the OTCQX International market. Read more: https://nightingalehealth.com/
