| Objective of Scheme | Provides EQA coverage for Fructosamine assays used in the management of diabetes when the presence of haemoglobin variants means that HbA1C alone cannot be used to monitor Diabetes. This Scheme provides endogenous samples that cover both the normal (non diabetic) and pathological (diabetic) concentration ranges |
