Autoimmune Encephalopathy Profile

Test Number 505535

Test number copied

CPT 86255(x22); 86341

Synonyms

Autoimmune Encephalitis Panel
Paraneoplastic

Test Details

Methodology

Immunofluorescence, EIA, Immunoblot

Result Turnaround Time

5 - 7 days

Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Use

For the detection of antineuronal autoantibodies that help in the diagnosis of paraneoplastic syndromes and autoimmune encephalopathies and related conditions

Limitations

This test was developed and its performance characteristics determined by Labcorp in accordance with CLIA requirements. This test has not been cleared or approved by the Food and Drug Administration.

Custom Additional Information

This test should be considered for the differential evaluation of encephalopathy of unknown origin with subacute onset of seizures, confusion, memory loss, and/or behavioral change. For adults and patients with suspicion of cancer, additional evaluation of paraneoplastic autoantibodies is recommended; refer to Autoimmune Neurology/Paraneoplastic Profile [505500].
