INDIVIDUAL TEST 355

Sulfatide Antibodies (IgM)

Indication

Suspicion of polyneuropathy

Sample material

Serum

• Minim. volume: 0,5 mL
• CSF
• Minim. volume: 0,5 mL

Transport

• Within Sweden: room temperature
• International: cold

Method

ELISA

Reference interval

< 10 negative, 10-15 borderline

Result

Results are reported as negative, borderline or positive with a ratio.

Interpretation

IgM antibodies against sulfatide are predominantly present in patients with antibodies against myelin-associated glycoprotein (MAG) but isolated findings occur in cases with neuropathy. The clinical value is limited.

IgM antibodies against sulfatide are rarely found in CSF and the clinical value is low.
