Blood samples from veterinary practices throughout the UK were submitted for trace element analysis. Erythrocyte glutathione peroxidise (eGSHPx) (colorimetric assay) was expressed in terms of haematocrit and plasma selenium (PlSe) (ICP) analysis from 1767 samples submitted between November 2006 and June 2009. Samples were included under the following criteria: both analyses were performed, were cattle, not haemolysed (Pl Fe >1000mmoll-1) and were processed within 4 days of sampling.
