Wieslab Laboratory Services is proud to be one of the first diagnostic laboratories in Scandinavia to offer an extended panel for Small Fiber Neuropathy (SFN) testing in serum.
In close collaboration with key healthcare professionals, we have developed an extended panel to support identifying the underlying SFN cause when there is no clear etiology.
Diabetes, sarcoidosis, hepatitis C, autoimmunity, Sjögren's syndrome, vitamin deficiency, toxic exposures, amyloidosis, paraneoplastic syndromes, and some rare genetic disorders have been reported as causes of SFN. However, the underlying cause is often unclear in a significant percentage of patients.
SFN can overlap with other muscle/pain syndromes and can be found in fibromyalgia, associated with muscle cramps and complex regional pain syndrome. SFN has been reported in up to 40% of patients with fibromyalgia.
Treatment of SFN is based on the primary cause. Determining the underlying cause for SFN in serum facilitates patient care.
