ABSTRACT
During an 18-month period, we evaluated the LINEAR KGT 3/4 'cloud' tonometer and found the reproducibility of results in replicate assays to be excellent, with a narrow range of standard deviations. Equilibrium efficiency high, and temperature stability and pH re-equilibration were excellent. Whole-blood tonometry involved minimum exposure to the technologist and could be satisfactorily accomplished from a single blood pool for at least 22 hours. Consumption of calibration gases was low (less than 4 ml/min per level), operator time minimal, and cost per assay for aqueous-buffer samples estimated to be about $0.08.

Sixty-seven digoxin-containing sera were analyzed by both radioimmunoassay and EMIT. After some important modifications of the EMIT method, agreement between the two methods was very good. Reproducibility of the EMIT assay was excellent; daily variations in values found for control sera were quite small, and recovery of added digoxin was good. Slight hemolysis hadnegligible effects, but highly hemolyzed specimens gave low recoveries of digoxin.
