QUARTZ - Forensic blood toxicology schemeQUARTZ is a blood toxicology scheme and isdesigned for laboratories undertaking analysis ofdrugs in post-mortem and other blood samples fortoxicological purposes, particularly in a forensiccontext. Test materials are prepared by spikingpre-screened human blood, which are assessedfor homogeneity prior to despatch.The analytes to be determined in each round arefrom a list, compiled by the Advisory Group, ofnon-prescription, prescription and controlleddrugs, as well as other toxins, which reflect whatparticipants are likely to encounter in forensiccasework.Test materialGroup AMore frequently determined drugsAnalytes6MAM (MACM), Amfetamine,Amisulpride, Amitriptyline,Benzoylecgonine, Buprenorphine,Carbamazepine, Chlordiazepoxide,Chlorpromazine, Citalopram,Clomipramine, Clozapine, Cocaine,Codeine, Cyclizine,Desmethyldiazepam, Diazepam,Diclofenac, Dihydrocodeine,Diphenhydramine, Dosulepin,Fentanyl, Fluoxetine, Ibuprofen,Imipramine, Ketamine, Lamotrigine,MDA, MDMA, Methadone,Methamphetamine, Midazolam,Mirtazepine, Morphine, Olanzapine,Oxazepam, Oxycodone,Paracetamol, Paroxetine, Pethidine,Phenytoin, Procyclidine,Promethazine, Propoxyphene,Quetiapine, Risperidone, Salicylate,Sertraline, Temazepam,THC,THC-COOH,Tramadol, Venlafaxine,Zolpidem, Zopiclone.OtherPT schemesThe drugs used are subdivided into two groups:Group A those drugs that are more frequentlydetermined by participants.Group B those drugs that may be lessfrequently determined by participants.Test material will contain between 0 and 4 drugs andup to three samples are provided in each round.Alcohol is a major cause of road casualties anddeaths and as penalties for drink-driving aresevere it is essential the accuracy of analysiscan be proven in the legal case. The test materialcomprises 10ml vial of whole blood containingalcohol for analysis. The full range and availabilityof test materials in QUARTZ is determined on anannual basis and further details can be found in theQUARTZ application form and scheme description.Group BLess frequently determined drugsTest materialDrug IdentificationDrug QuantificationAmlodipine, Amobarbital, Atenolol,Benzyl piperazine (BZP),Butobarbital, Clobazam,Clomethiazole, Clonazepam,Dextromoramide, Dipipanone,Gabapentin, Loprazolam,Lormetazepam, Mefenamic Acid,Methylphenidate, Naltrexone,Pentobarbital, Phenelzine,Propranolol, Secobarbital,Sildenafil, Thioridazine,Trazadone, Zaleplon.Note: Metabolites of the above substances may also be added.AnalytesParticipants will be asked toidentify the drug(s) only. The testmaterial will always (if positive)contain one drug from Group A.Up to three other drugs may bein the test material from eitherGroup A and/or Group B.Participants will be told the identity,or generic classification, of thedrug(s), and asked to quantify theconcentration. They will also beasked to give an interpretation ofthe results in respect to a casestudy provided. The test materialwill always contain a drug fromGroup A. Any other drugs presentwill be from Group A and/or Group B.Drug Quantification*Alcohol QuantificationStandard solutions containingdrugs for the evaluation ofinstrumentation.Participants will be required toquantify the alcohol concentrationby their usual methodsNote: Test materials and analytes may be added or removed, pleasesee current application form. *Please note the Alcohol test material iscurrently not included in our scope of accreditation46 Tel: +44 (0)161 762 2500 Fax: +44 (0)161 762 2501
TOYTEST - Toy safety schemePlay is a vital part of child-development and toyshelp at every stage from babies to school-agechildren. Toys are safer than ever before, butwe should remain cautious about often hiddenhazards of toys. We rely on manufacturers,suppliers and toy legislation to help keep ourchildren safe and at the same time preventproduct recalls and protect brand value.With an international reputation as a leadingindependent PT supplier, <strong>LGC</strong> <strong>Standards</strong>TOYTEST scheme allows laboratories involved inthe safety <strong>testing</strong> of toys to monitor their analysisagainst the current European and Americanstandards. Participation in TOYTEST will enablelaboratories performing tests on toy productsto monitor their performance and compare withthat of their peers.Test materialTest usually a toy material ortoy partA paper exercise relating to theinterpretation and inspection of toysA standard solution containingmetals at levels similar to atypical extractSection of material and/orstandard solutionDried paint flakesSection of plastic materialAnalytesEN71-1: Test material for analysisand assessment against standard.EN71-2: Test material forflammability <strong>testing</strong>.EN71-3: Test material and <strong>Standards</strong>olution provided for metal analysis.EN71-7: Information provided forassessment against standard.EN71-8: Information provided forassessment against standard.EN71-9: Test material for analysisand/or information provided forassessment against standard.ASTM F963: Test materialassessment against standard.Azo dyes.ASTM: Total Lead.Phthalates.Test materials are assessed against therequirements of EN71 (European Standard)and ASTM (American Society for Testing andMaterials F963) toy safety standards.A comprehensive range of test materials will beincluded over the scheme year to be assessedagainst the regulations; however, not all parts ofthe standards will be assessed over a schemeyear. Participants will be given clear instructionsas to which parts of the standards are to beassessed.Note: Test materials and analytes may be added or removed, pleasesee current application form.OtherPT schemesTest materials will also be provided for analytical<strong>testing</strong>, such as paint flakes for lead analysis,and standard solutions for heavy metal analysis.Further tests may be added at the discretion ofthe Advisory Group.The full range and availability of test materialsin TOYTEST is determined on an annual basisand further details can be found in the TOYTESTapplication form and scheme description.Email: customerservices@lgcpt.comWebsite: www.lgcpt.com47
