A Guide to Evaluating Your Laboratory Performance

ABSTRACT.

The purposes of this paper are to: 1. acquaint EEG personnel with common technical errors in the laboratory, 2. suggest methods that may assist in avoiding such errors and 3. pose questions that enable a technician to evaluate the quality of his performance in the laboratory.

The major sources of errors in laboratory performance are in assuming that: 1. you are always right, 2. all EEG's must be done the same way and 3. that analyzing artifacts, state of alertness, degree of abnormality (if any) and location can be done after the recording is completed.
