A Practical Method to Measure GFR in people with type 1 diabetes

Iohexol clearance measured with DBS performed better than eGFR methods. Correction for ambient blood glucose improved precision and accuracy of GFR measurement. This method is more convenient than the gold-standard GFR method and may improve screening and diagnostic capabilities in people with type 1 diabetes, especially when GFR is >60 ml/min/1.73 m2 (Diabetes and Its Complications)
