The erythrocyte density microtest is a technique that is being assessed for the diagnosis of perinatal hypoxia, a pathology with a high incidence in the neonatology services. This technique is used to measure the percentage of young nucleated red blood cells. As the rat blood coagulates rapidly, the original technique was modified. This technique was applied to conduct a serial study in young rats (from 1 to 14 days) and to have a control group to compare its values with those of hypoxic rats. In the results it was observed a decrease of the values with age, which should also occur in children after birth. Therefore, it is suggested to carry out a similar study in normal infants at term that will serve as a pattern of comparison with the cases of hypoxia
