INDIVIDUAL TEST 804
TS-HDS Antibodies (IgM)
Indication
Small fiber neuropathy
Method
The analysis was performed with EIA. This method is not yet validated for clinical diagnostic use.
Answer
Results are reported as negative or positive with a value.
Interpretation
IgM-antibodies against TS-HDS are reported in a subgroup of patients with small fiber neuropathy (SFN) with unknown underlying cause. These antibodies activate complement and immune therapy may be effective, clinical trials are ongoing. TS-HDS IgM seems to be more frequent and specific for SFN than IgG-antibodies against fibroblast growth factor receptor 3 (FGFR3).

ENSKILD ANALYS 804
TS-HDS-antikroppar (IgM)
Indikation
Fintrådsneuropati
Metod
Analysen har utförts med EIA. Metoden är ännu inte validerad för klinisk diagnostik.
Svar
Svaret anges som negativt eller positivt med värde
Tolkning
IgM-antikroppar mot TS-HDS har rapporterats förekomma hos en undergrupp av patienter med fintrådsneuropati utan annan känd underliggande orsak. Antikropparna är komplementaktiverande och immunmodulerande behandling kan ha positiv effekt, kliniska studier pågår. TS-HDS IgM förefaller vara vanligare och mer specifika för fintrådsneuropati än IgG-antikroppar mot fibroblast growth factor receptor 3 (FGFR3).
