Sequential CK and LD isoenzyme interpretation by microcomputer.

A microcomputer program for rapidly interpreting and reporting sequential creatine kinase and lactate dehydrogenase isoenzymes written in BASIC is described. The program uses a combination of algorithmic logic and matrix-searching functions, correlates abnormalities from up to three patient samples, and arrives at a pattern diagnosis. Program execution is simple and has proved reliable in 1,000 samples from a large university hospital and a medium-sized community hospital.
