Medical testing company Randox has unveiled a new clinic in Co Down.
The Northern Ireland business, which is headed by Dr Peter FitzGerald, launched the centre in Holywood yesterday with the help of Arlene Foster.
The building houses one of the company's Evolution blood-screening machines, which is capable of delivering accurate results from more than 2,600 tests an hour.
Mrs Foster said the business "occupies a special place in Northern Ireland".
"For almost 35 years, it has been a global leader in medical diagnostics," she added.
"Dr Peter FitzGerald has dedicated himself completely to improving people's health around the world, and we see the results of that here in this clinic, which I am delighted to open to the public.
"I fully embrace his philosophy of preventive health and doing what we can to stay healthy, living fuller lives for longer."
Dr FitzGerald said: "Right across society, I see too many people struggling with preventable illness. Conditions like type 2 diabetes, described as the fastest-growing epidemic of our time, are having a catastrophic impact on people's lives."
The Crumlin-based firm has grown into a major business, mainly based here.
The company has a turnover of nearly £96m, with pre-tax profits of close to £18m.
It also has a workforce of 1,400, including more than 900 people locally.
