Abstract

The contamination caused by rubber stoppers of collection tubes preceding the determination of zinc in plasma and serum was investigated. The use of evacuated blood collection tubes (EBC-tubes), normally used for the collection of serum samples, could give rise to an average artificial increase of normal serum zinc concentrations of about 250%. Heparine containingebc-tubes, used for the collection of plasma, and plainebc-tubes of an experimental production appeared to be suitable for correct zinc determinations. There was no difference between the serum and plasma zinc levels of fifty volunteers.
