Elevated urinary lead concentration is indicative of chronic lead toxicity. Urinary lead concentrations may be used to monitor detoxification therapy. Increased urine lead excretion rate indicates significant lead exposure. Measurement of urine lead excretion rate before AND after chelation therapy has been used as an indicator of lead exposure. An increase in lead excretion rate in the post chelation specimen of up to 6 times the rate in the prechelation specimen is normal. Blood lead is the best clinical correlate of toxicity.
