Normative Data of Intra-epidermal Nerve Fiber Density

April 12, 2019 updated by: University Hospital, Strasbourg, France

Establishement of Normative Intra-epidermal Nerve Fiber Density Using Skin

Intra-epidermal nerve fiber density can be assessed using skin biopsy. A decrease of this density is used to diagnose small fiber neuropathy, despite the absence of normative data in a selected normal population. To establish a normative set of data matched for age and sex is absolutely needed to evaluate the sensibility and specificity of this test.
