US Classification:

422 8205

Abstract:

An instrument for analyzing test strips supporting chemistries which react with a medically significant component of a body fluid to indicate the concentration of the component in the body fluid. The instrument includes a pathway along which radiation is guided from a radiation source to a strip when the strip is inserted into the instrument and along which remission is guided from the strip to a radiation detector. A title provided on the instrument provides a first remission when no strip is inserted into the instrument. The tile is separated from the radiation source by the strip when the strip is inserted into the instrument. The first remission and the strip's remission, respectively, indicate the absence and the presence of the strip in the instrument. The strip also has a surface opposite the chemistry supporting surface characterized by a second strip remission different from the first strip remission. The instrument is capable of determining whether the strip has been inserted into the instrument correctly or backward.
