Measuring a person's blood lead level requires a blood sample, which may be performed with a fingerstick or a blood draw. The amount of lead found in the blood sample may be measured in micrograms of lead per deciliter of blood (μg/dL) especially in the United States; 5 μg/dL is equivalent to 0.24 μmol/L . [6]
Elevated blood lead levels (BLLs) in adults can damage the nervous, hematologic, reproductive, renal, cardiovascular, and gastrointestinal systems.. Current research continues to find harmful effects in adults at BLLs previously considered harmless, such as decreased renal function associated with BLLs at 5 micrograms per deciliter (μg/dL) and lower, and increased risk of hypertension and ...

These statistics first helped defeat a petition from the Lead Industries Association to relax the law and then, in 1985, to ...

Blood lead concentrations in poisoning victims have ranged from 30 to 80 μg/dL in children exposed to lead paint in older houses, 77–104 μg/dL in persons working with pottery glazes, 90–137 μg/dL in individuals consuming contaminated herbal medicines, 109–139 μg/dL in indoor shooting range instructors and as high as 330 μg/dL in ...
