Urine Validity Testing Sample Clauses

Urine Validity Testing. The aim of validity testing is to demonstrate that the sample submitted for analysis is unadulterated and undiluted urine. The minimum validity tests that must be performed are pH, creatinine and the presence of oxidising agents including materials for cleaning teeth and sterilization tablets provided by prisons for cleaning purposes. Please provide detailed protocols for all of the validity tests carried out, as listed in the specification, including validation data and interpretation and reporting of results. Concateno UK Urine samples submitted for Drugs of Abuse testing can be adultered in a variety of ways, either by substitution, dilution or addition. Substitution: a urine sample from another person or animal is provided and passed of as the donors own sample, or another fluid resembling urine might be provided. Examples include diluted fruit juice, lager, coloured tap water etc. Dilution: can be either in vitro (diluting the urine sample after collection) or in vivo (drinking large quantities of fluid before providing the sample). Both methods attempt to lower the drug concentration in the urine to below the cut-off levels of the assay required. Addition: addition methods attempt to interfere with the assay techniques themselves, either screening or confirmation assays. Examples of such chemicals include oxidizing substances, which alter the chemical structure of the target drug(s), affecting both screening and confirmation assays. Examples include bleach, perborate (Bocosan) and nitrite (urine “Klear”) which also interferes with derivatisation procedures used in confirmation assays. These are screened for with an in-house test for oxidant assay. More recently, sterilising tablets containing dichloroisocyanurate have been tested, the active ingredient being chlorine. Unfortunately, chlorine rapidly dissipates giving a negative oxidant test; therefore an assay for the detection of the residual cyanuric acid has been developed and is used for detection. Addition of glutaraldehyde or soap may denature the protein based antibodies and enzymes used in most screening assays, and acid/alkalis can be used to drastically alter the pH of the urine and interfere with immunoassay procedures (i.e. vinegar, caustic soda etc). Applying dynamic range limits detects any disruption to the background enzyme activity caused by these additions. Concateno employs a range of sample validity tests and has developed several specialist procedures to counteract the use of kno...
