An increase in the use of routine automated laboratory profile screening, included as an essential part of each annual health evaluation, has been predicted and urged by various authorities. Three recent studies indicate 10% of those screened will show some major chemical abnormality. One key specialist in the evaluation of any person's health status is his family physician. This report considers data from a fourth study, consisting of 1,084 consecutive automated laboratory profiles secured on 832 adult patients having health evaluations performed by their family physician. Both patient and physician benefit greatly. The suggestion by many authorities that the apparently healthy person as well as the obviously sick patient be routinely studied by automated laboratory profile screening seems justified.
