摘要：

A forensic test, designed to detect blood at crime scenes, was applied to EEG surface electrodes after routine EEG recordings. The EEG recordings were performed at a teaching hospital by experienced technologists in compliance with standards set by the American EEG Society. Seven out of 574 electrodes (1.2%) were positive for the presence of blood. None of the positive electrodes had visible blood on the electrode or at the electrode site. Three of the positive electrodes Mere from sites at which both abrasive skin prep and a blunt needle were used to lower impedance, three of the positive electrodes were from sites at which only abrasive skin prep was used to lower skin impedance; far one positive electrode the method of impedance reduction was not documented.
