The only acceptable tubes for collection of blood for serum zinc which
I have come across are the Becton Dickinson trace element-free
vacutainer tubes (blue top - no additive - ref 367737).
I would not accept any alternative, although these tubes are
relatively costly: others all contain significant amounts of zinc,
especially in the rubber cap.

Do members have experience of any problems with anticonvulsants
and zinc analyses.What is the recommended sample type for zinc?
