Enzyme immune assay - portable microcomputer interfaced system

This paper describes an enzyme immune assay system interfaced with microcomputers. Developed initially for Hewlett-Packard 9825A microprocessor, the system now utilizes an Apple II Plus with two disk drives, a printer and a monitor. The system stores values read by a multi-channel spectrophotometer, keeps records and generates reports. The system was created with portability in mind and has been tested successfully in Africa. Information collected in the field is sent to a mainframe computer via modem for further statistical analysis. It functions well in the hospital, laboratory and remote field settings.
