通过口腔液体检测药物滥用的设备由Varian公司研制成功

一种独特的待批准的设备可以极其方便地收集口腔液体（唾液）并提供经过认证实验室的检测结果。

该设备被称为OraTube，其收集装置无液体渗漏，操作简单，从样本收集到传送只需要三个步骤。操作是非侵入的而且100％可监控的，收集过程几乎杜绝了对样品做手脚的可能，简化了样品保管链。操作者将OraTube收集器送到近OraTube认证的药品检测机构。在24小时之内就可以获得阴性结果，在48～72小时内可以获得经过认证实验室的确认结果。

OraTube是Varian公司the Oniste OraLab的延伸产品。OraTube被用在雇佣前测试、随机的被怀疑者或者事故发生后，进行安非他明、可卡因、甲基苯丙胺、摇头丸、吗啡以及其他滥用药品的测试与筛查。与竞争对手产品不同，OraTube的设计无需在实验室检测前稀释样品，因此在预期临界值水平结果更加准确。

Varian公司消耗品副总裁兼总经理Stephen Schultheis解释说：“对口腔液体进行测试的需求正在不断增长，因为这收集尿液更加方便。如果用户需要检测近期的药物滥用，口腔液体检测是理想的选择。”

Lab-Based Testing Device for Oral Fluid
 
A unique patent-pending device combines the convenience of onsite oral fluid (saliva) collection with laboratory-certified results.

Called OraTube, the collection device is drip-free, simple to use, and includes only three quick steps from sampling to shipping. Noninvasive and 100% observable, the collection process nearly eliminates specimen tampering and simplifies chain-of-custody procedures. Users ship the OraTube collector to an OraTube-certified drug-testing facility. Negative results are available within 24 hours, and laboratory-certified confirmations are available within 48-72 hours.

OraTube is an extension of the Onsite OraLab of Varian, Inc. (Palo Alto, CA, USA). OraTube is used for pre-employment testing, random suspicion or post-accident testing and screening for amphetamines, cocaine, methamphetamine, ecstasy, morphine, and other drugs of abuse. Unlike competitive offerings, OraTube’s design does not require the dilution of the sampler prior to laboratory testing, and therefore results are more accurate at the desired cutoff levels.

“There is growing interest in oral fluid testing because of the many benefits over urine collection,” explained Stephen Schultheis, consumable products vice president and general manager, Varian Inc. “If a customer wants to detect recent drug use, oral fluid testing is the ideal choice.”
