Forensic Blood Toxicology (QUARTZ)

Our QUARTZ scheme is aimed at laboratories undertaking forensic toxicology and coroners' work. Test analytes and case scenarios included in the scheme are discussed regularly with our Advisory Group.
QUARTZ offers the choice of a number of test materials, comprising blood and urine spiked with drugs and metabolites. Case scenarios provided for interpretation include sudden and suspicious deaths, drug-facilitated sexual assaults (DFSA), impaired driving and other relevant cases.
We also supply an Alcohol Technical Defence (ATD) exercise that allows practitioners to demonstrate competency in performing these types of calculations.
Participation in QUARTZ will provide independent performance assessment and confidence that results are meaningful and accurate. Consistent good performance will allow laboratories to demonstrate to third parties, customers, regulators and accreditation bodies the quality of their results.
The operation of our QUARTZ scheme is supported by an Advisory Group consisting of members of professional bodies, scheme participants, and others experienced in the field.
