The Collection and Preparation of Human-Blood Plasma or Serum for Trace-Element Analysis

Abstract

Trace element concentrations in blood plasma or serum have been assayed by numerous investigators using a variety of analytical techniques. For several elements, figures obtained in different centers are widely disparate. Impressive evidence has accumulated that a great deal of the inconsistencies should be ascribed to unsuspected contamination of the samples with exogenous material during their collection and preparation. In this paper, a number of potential sources of extraneous additions are indicated. Methods for controlling contamination are also briefly discussed.

“…The samples were taken to the laboratory for centrifugation to obtain blood serum for chemical analysis. To convert the serum samples into solutions for elemental analysis, microwave acid digestion method was employed using concentrated HNO3 and concentrated H2O2 [14][15][16][17]. A MARS Xpress Technology Inside Microwave System was used to perform the extraction employing the EPA 3051 method.…”
