Abstract: | The reference volumes of erythrocytes and blood platelets were evaluated for different age groups of children. The mean volume of cells and the parameters of its distribution, i.e. SD, As and Ex, were found. The mean volume of erythrocytes and the value of positive Ex for the volume of blood platelets were shown to be reliably higher in adults. The investigated blood parameters in children were proven to depend in children on their age and sex. It was concluded that the mentioned peculiarities should be considered in the practice of clinical laboratory examinations. |
