Blood Test Detecting Autoantibodies to N-Methyl-d-aspartate Neuroreceptors for Evaluation of Patients with Transient Ischemic Attack and Stroke

Abstract

NR2A/2B aAbs are independent and sensitive serologic markers capable of detecting TIA with a high posttest probability and, in conjunction with neurologic observation and neuroimaging, ruling out ICH. The test may help assess risk of TIA in routine general practice and may potentially be useful in assisting diagnosis of acute IS in the emergency setting.
