Stage 1

Almost 18,000 participants joined COMPARE between February and May 2016 when attending their routine blood donation session.
Over 12,000 participants have attended their second donation visit to date.
At the second visit, the different methods for measuring haemoglobin levels are being tested, including a non-invasive device and capillary hemocue. A blood sample is also taken and measured using a “gold standard haematology analyser”.
The non-invasive devices and capillary hemocue will only be available until the 25th September 2016.
