[Chemical method for the determination of fetal hemoglobin at low concentrations]

A new method of determination of foetal haemoglobin by means of the alkali denaturation is described. This method allows to determinate low levels of foetal haemoglobin and that is an important date in the screening of beta-thalassemia where the per cent of foetal haemoglobin is only a little increased than in physiological condition.
