A recent review has been published in The Lancet Diabetes & Endocrinology, showing the utility
of SUDOSCAN in the early diagnosis of diabetic peripheral neuropathy (DPN).

Early detection of DPN is a key point in the management of diabetic patients; indeed, DPN is a principal cause of diabetic foot ulceration and can lead to foot amputation.

As DPN is a marker of diabetic complications, the authors propose using point-of-care testing to screen for various diabetes complications in a single visit. Large and small fiber assessments (DPN-Check and SUDOSCAN, respectively) can be performed easily to identify neuropathies as shown in the pattern below.

Clinical utility of SUDOSCAN for the diagnosis of diabetic peripheral neuropathy: sensivity 87,5%, specificity 76,2%, intra-observer intraclass correlation coefficient 0,88 and inter-observer intraclass correlation coefficient 0,95

Proposed assessments for a one-stop screening clinic for diabetes complications,
including use of point-of-care devices for DPN
