Healthcare institutions are busy places. A 400-bed hospital can see hundreds of thousands of patients a year. Millions of blood tests will be taken, analysed and the results sent back for diagnosis and medical intervention. The chance of error is small, often only 2 in every 1,000 tests, but the consequences can be enormous. And, with so many tests being processed, even a small chance of error means that thousands take place in every hospital, every year.
