Specimen Acceptability

Methods
Inductively Coupled Plasma/Mass Spectrometry (ICP/MS) Includes arsenic, cadmium, lead, and mercury. NOTE: Mayo Medical Laboratories offers both an essential elements screen and a heavy metals screen. In the case when a metals screen is ordered, we will assume this to be a heavy metals screen request. In case we have misinterpreted your request, the specimen will be retained for 2 weeks following testing during which time you may call and request other testing.
