DIAGNOSTISK ANALYS 006
CASPR1-antikroppar (IgG)
Diagnostisk analys för antikroppar mot CASPR1 (IgG) vid misstanke om inflammatorisk neuropati/autoimmun nodopati.
Indikation
Misstanke om inflammatorisk neuropati/autoimmun nodopati

Tolkning
Contactin-associated-protein 1 (CASPR1) är ett paranodalt protein. IgG antikroppar mot CASPR1 har beskrivits vid autoimmun nodopati.
