Intended Use

The DETECTABUSE® Liquid control is an In Vitro Diagnostic (IVD) device, for prescription use only, that is intended for use as quality control urine to monitor the precision of laboratory urine toxicology testing procedures for the analytes listed in the package insert.

Summary and Explanation

The DEA exempt DETECTABUSE® product line of controls is manufactured using a human based matrix that has been stabilized to insure that the product will be viable until the date of expiration. Positive controls are spiked with reference drug standards and/or appropriate metabolites that have been obtained from certified manufacturers. Standards are certified by the manufacturers to be at least 98% minimum purity. Specific gravity, pH, and creatinine fall within the limits of normal human urine.

Description

Each bottle contains stabilized human based urine. Positive control urines have been spiked with authentic reference drug standards and/or appropriate metabolites. Negative control urines are certified negative by combination of Immunoassay, GC/MS and/or LC/MS for the constituents listed on our target sheets. They should be treated as any "unknown” specimen while following the specific protocol of the assay being used. This product is intended to be used by health care professionals as an integral part of good laboratory practices.

Storage and Stability

Please refer to Limitations for detailed instructions.

Unopened:

  1. The controls are stable until the expiration date when stored at 2° to 8°C (Oxazepam is stable for only 6 months).
  2. Store -10° to -20°C to extend the Oxazepam stability, up to 3 years or until expiration date, whichever comes first.

After Opening:

  1. The controls are stable for 31 days or until the expiration date, whichever comes first, when stored tightly capped at 2° to 8°C.
  2. The controls are stable for six months or until the expiration date, whichever comes first, when stored at -10° to -20°C. Controls can be thawed/frozen up to 5 times.

    3. Procedure

    Allow controls to come to room temperature followed by gentle swirling or inversion before use. DO NOT SHAKE. Transfer an appropriate aliquot of DETECTABUSE® control urine as required by the drugs of abuse test device or screening method.

    Expected Results

    The positive DETECTABUSE® control must test positive on the drugs of abuse test device or screening method. The negative control must test negative.

    Precautions

    For In Vitro Diagnostic Use Only. Please read the entire package insert before using the DETECTABUSE® control urines. Please use the same safety precautions you would use for processing any "unknown” urine sample containing potentially infectious biological material. Protect product from exposure to direct sunlight. Contains sodium azide: To prevent formation of explosive metal azides dispose of waste by flushing with copious amounts of water or according to local governing regulations.
    Do not use beyond the expiration date.

    Limitations of Procedure

    This control is meant to be used to validate the performance of immunoassay drug screening methods. Consult test manufacturer’s instructions when using this product; changes in reagents, sample requirement, or methodology may affect test results. Although target values are provided with the DETECTABUSE® liquid controls, each laboratory should run these controls as unknowns in order to establish “in-house” assay values for them.

    Detectabuse® Controls, Oxazepam Stablity:

    Oxazepam has known stability problems in urine stored refrigerated, our studies indicate that Oxazepam will deteriorate when stored refrigerated for longer than 6 months from date of receipt.

    Detectabuse® Controls, THC Stability:

    DETECTABUSE® controls are stable for the length of time under the storage conditions stated in the package insert. In spite of this fact, under certain conditions, there may be observed a gradual decline in THC levels, over time, from continuous use of a single bottle of control material. This drop in THC values may occur from any THC sample (i.e. calibrators, controls, and samples). The apparent loss of THC most often occurs from handling and not from product instability.

    It is well known that THC-COOH binds to surfaces, especially certain plastics.
