[Lead automated microdetermination in capillary samples of blood by a flameless atomic absorption spectroscopy (author's transl)].
A method for lead determination in capillary samples of blood based on flameless atomic absorption spectroscopy in connection with an automated microsampling system is described. For such determinations 50 microliter of heparinized whole blood samples from the fingertip or from the ear lobe are sufficient. Immediately after sampling blood is diluted in ratio 1:5 by an aqueous 0.05% Silicon Antifoam solution. Correlation between lead capillary from the same subjects and venous blood levels sampled from the same subjects and in the same sampling session is highly significant and well suited for routine clinical use.
