Abstract
Abstract A microprocessor controlled data analyzing system is provided for use with a clinical spectrophotometer, such as the Abbott Bichromatic Analyzer (ABA-100), which is used for testing samples of serum derived from patients' blood. The data analyzing system of the invention serves to analyze the outputs from the spectrophotometer, and to transform the outputs into reportable units. The data analyzing system is capable of providing the operator with full instructions as to any particular test and to control the spectrophotometer to perform such a test.
