'Why report eGFRS over 60?'
Renal experts are suggesting
reporting eGFRs above 60 in general practice is a waste of time and is causing unnecessary confusion among doctors.
Some laboratories are considering limiting detailed reporting to eGFR values below 60 amid reports that some GPs are over-diagnosing chronic kidney disease or referring patients inappropriately.
Dr Edmund Lamb, who reviewed the robustness of eGFR at a CKD conference this week, said: 'Many international organisations recommend we don't report eGFR if it is greater than 60.'
Dr Lamb, renal expert for the Association for Clinical Biochemistry, added: 'In the UK we went for 90. That's possibly something we'll need to revisit.'
There are concerns some GPs are diagnosing patients with CKD who have eGFRs between 60 and 90 and lack additional risk factors.
Dr Damian Fogarty, senior lecturer in nephrology at the school of medicine, Queen's University Belfast, said: 'We report at less than 60, and there's poor evidence for reporting between 60 and 90.'
But some delegates said they did not want to see reporting above 60 removed because the results could still indicate a problem in some patients.
Dr Lamb also said there was a lack of evidence for use of eGFR in the very elderly and in certain ethnic minorities.
