Another way to detect the levels of Pb in urine examination which is more than 0.2 micrograms / liter or more than 600 micrograms in a 24-hour urine capacity. Otherwise, it could also X-ray examinations on children to see a radio-opaque lines on a metaphysical as well as the long bones can be done to find high lead levels in the body.
