Interpretive Data


Compliance Statement D: For laboratory tests using a manufactured RUO kit. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use. The results are not intended to be used as the sole means for clinical diagnosis or patient management decisions.

Note
The Asialo-GM1 Antibodies, IgG/IgM component of this test is unavailable due to a nationwide manufacturer reagent issue. The result of this individual component alone has minimal clinical significance but can support an overall clinical diagnosis in conjunction with other clinical parameters and/or other motor neuropathy markers. The other panel components are not affected by this reagent issue and will be reported within the published turn-around time.
