Non-panel testing for autoimmune neuropathies. Test by itself is not diagnostic and should be used in conjunction with other clinical parameters to confirm disease.
Semi-Quantitative Enzyme-Linked Immunosorbent Assay
Serum separator tube.
Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.1 mL)
Plasma or urine. Contaminated, heat-inactivated, hemolyzed, icteric, or severely lipemic specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year
Less than 1.00 IV
The majority of SGPG IgM positive sera will show reactivity against MAG. Patients that are SGPG IgM positive and MAG IgM negative may have multi-focal motor neuropathy with conduction block.
