[Use of the Reflotron system for laboratory diagnosis in swine and sheep]

The "Reflotron" system (Boehringer Mannheim) was compared with standard laboratory methods for determination of blood values, e.g. haemoglobin, glucose, urea, ASAT/GOT and GGT in pigs and sheep. Various different commercial control sera as well as blood and plasma samples from pigs and sheep were used for evaluation of its precision. The day-to-day precision of all parameters was satisfactory. The accuracy of the values was tested in 56(48) blood samples of healthy and sick pigs (sheep) by using standard substances (glucose, urea) and by comparing them with values measured by standard laboratory methods. There were systematic differences between "Reflotron" and other values in the glucose- and enzyme-values, which can be corrected with the help of conversion factors. In pigs, the enzyme GGT can not be determined accurately with the "Reflotron" system.
