Computer calculation of serum protein electrophoresis, based on peak height measurements.

A computer program has been written for off-line calculation of relative and absolute percentages of the five serum protein fractions usually seen on cellulose acetate electrophoretograms, with use of manually observed peak heights on densitometer scans. With myeloma-like peaks, both peak height and width at half-peak height must be measured. Routine application of the program saves technician time and decreases the number of large random errors.
