Abstract
Apparatus and method are disclosed for detecting the presence of a analyte in a sample. The apparatus includes an optical transmitter and receiver for transmitting light toward the sample and receiving a portion of the reflected light. The optical receiver acts in conjunction with a data processor to convert the reflected light to data representing the density of analyte in the sample. The apparatus thus disclosed is portable and can be transported to remote testing sites.
