Dr Simon Eaton of the Northumbria Diabetes Service told the All-Party Parliamentary Group for Diabetes that giving patients advance access to results would reduce unnecessary consultations.
Patients would have more time to reflect on the results and prepare goals before meeting with their GP, he said.
Dr Eaton argued this would improve quality of care and cut the healthcare burden from the 'exponentially rising' cost of treating increasing numbers of people with diabetes.
Research has suggested prevalence of type-2 diabetes will rise 98 per cent by 2020.
'We need to think about reducing unnecessary consultations. But to do it we need to help that person self care and make decisions effectively,' said Dr Eaton.
He compared a diabetes consultation with meeting a bank manager without knowing your statement or balance. 'We don't go to our bank manager for our statement, yet every day people with diabetes are going to see their GP to be told how they're doing,' said Dr Eaton.
