Frequent pathogenetic condition of hemoconcentration in calves results in apparent increase in the parameters of metabolic profile above the standard level. These values, however, do not conform to the actual state and often lead to unsubstantiated diagnostic conclusions with pathological deviations. On the basis of experimental study on the dynamics of some parameters of hematological, protein, mineral and electrolytic profile in the calves with experimental hemoconcentration, a correction table and diagram for the calculation of corrected values for some parameters of metabolic profile were elaborated. At hematocrit value increased above the physiologic limit (0.45--0.60) the correction values of parameters in percent are subtracted from the actual value. The correction table was used to correct actual values of those parameters of metabolic profile which during the experimental hemoconcentration were found to have direct relations to the dynamics (Er, Hb, Le, CB, Ig, serum Ca, P and Na). The correction of serum potassium and of some enzymes (AST, ALT, gMT) is not indicated because no relations were determined. Whereas the actual values of the studied parameters reached their maxima (statistically significant differences in Er, Hb, CB, Ig levels) at the culmination of hemoconcentration (6th hour--1st sampling), the differences between the corrected values and initial values were in all parameters insignificant. The correction of actual values of parameters by means of the diagram or table is simple, expeditious and reliable.
