Alphabetical Test listing

Lead, urine-994

Lead, urine
Pb, urine

Monitor exposure to lead or lead chelation therapy

Urine, random
5.0 mL
2.5 mL

Sampling time is not critical for industrial exposure monitoring. Metals with timing "not critical" have very long elimination half-lives and accumulate in the body over years, some for a lifetime. After a couple of weeks of exposure, specimens can be collected at any time.
