Detecting clinically significant lead exposure due to occupational exposure in random urine specimens
This test is not a substitute for blood lead screening.
Lead toxicity primarily affects the gastrointestinal, neurologic, and hematopoietic systems. Increased urine lead concentration per gram of creatinine indicates significant lead exposure. Measurement of urine lead concentration per gram of creatinine before and after chelation therapy has been used as an indicator of significant lead exposure. An increase in lead concentration per gram of creatinine in the post-chelation specimen of up to 6 times the concentration in the pre-chelation specimen is normal.
Blood lead measurement is the best test for clinical correlation of toxicity. For more information, see PBDV / Lead, Venous, with Demographics, Blood.
Only orderable as part of profile. For more information see:
-PBUOE / Lead Occupational Exposure, Random, Urine
-HMUOE / Heavy Metal Occupational Exposure, with Reflex, Random, Urine
Biological Exposure Index (BEI): <150 mcg/g creatinine
Urinary excretion of less than 4 mcg/g creatinine is not associated with any significant lead exposure.
Urinary excretion of more than 4 mcg/g creatinine is usually associated with pallor, anemia, and other evidence of lead toxicity.
