Detecting lead exposure
Nail analysis of lead can be used to corroborate blood analysis.
0.0-3.9 mcg/g of nails
Reference values apply to all ages.
Normally, the nail lead content is <4.0 mcg/g. Nail lead >10.0 mcg/g indicates significant lead exposure.
Blood lead analysis has the strongest correlation with toxicity.
