A Fortran IV computer program is described which identifies, computes, and statistically evaluates amino acid concentrations determined by an automatic amino acid analyzer in physiologic fluids. The program accepts retention time and integrated peak areas from two calibration standards for identification and computational reference. Two internal standards are used to compensate for variations in injector performance and ninhydrin decay. Calibration standard responses are statistically treated to assist in detection of equipment malfunction. The statistical data base is automatically expanded through inclusion of data from normal patients. Amino acid concentrations are printed with appropriate mean and standard deviation values in a format acceptable as a final report.
