[Lead levels in workers' blood and urine].

The relation between lead content in urine and blood of workers and the degree of manifestation of a disease is analysed in the paper. It has been found out that along with the increase in lead content in biomedia the severity of its effect on the organism is increased too. It has been shown that the determination of this element in urine is characterized by high diagnostic significance (more than 95%). The rate of lead excretion with urine increases with the increase of severity of a disease, and it is twice as much in people with chronic lead intoxication compared to that in practically healthy workers. It is proposed that determination of urine lead content be included as an obligatory test into the examination of workers in contact with lead.
