The age dependence of haemoglobin denaturation temperature in the composition of erythrocytes is established. Children have a much more expressed correlation of this temperature depending on the type and stage of disease than the adult. It is found that children ill with leukemia have haemoglobin, the value of heat denaturation of which is decreased about 15-25% in relation to the norm.
