Ethanol in urine, Carboxyhaemoglobin, Toxicological case studies and a range of toxicological analytes for quantitation in blood. 2ml samples of liquid human serum, blood or urine spiked with ethanol and 5 samples of whole human blood containing variable proportions of carboxyhaemoglobin or drugs. The latter analysis is also used twice a year to prepare a summary report of data from the previous 12 months. Comparisons of the precision and accuracy of assay techniques are performed at regular intervals for publication.
Participants receive all such reports and can request details of preliminary findings.
Quantitative toxicology scheme in blood. Some distributions of toxicology case studies will be undertaken in collaboration with the Dutch KKGT scheme.
