Varian公司开发急诊科使用的药物滥用检测方法

 
 
一种新型床边检测方法是一种快速体外诊断检查，能够确定医院急诊科就诊的患者是否受到了药物滥用的影响。

OnTrak TesTcard 9能够定性筛查下述尿液中的药物：安非他明、巴比妥酸盐、苯二氮、可卡因、脱氧麻黄碱、吗啡、苯环己哌啶、四氢大麻酚、三环抗抑郁药。这种一步法检测不需要对试剂进行混合、定时、孵育或者特殊处理。对这九种药物的检测结果在3~5分钟之内就可以得出，开发商声称比同类竞争产品快3倍。除此之外，这些检测结果在长达6小时的时间内保持稳定。

这种检测方法是美国Varian公司的产品。Varian公司消费产品部副总裁兼总经理Stephen Schultheis指出：“TesTcard 9为我们提供机会，将我们的床边诊断产品从犯罪鉴定和现场应用扩大到了临床应用。这种临床POC应用对Varian公司而言是一种令人鼓舞的新机会，因为我们可以评估产品和新技术未来的发展，这将会为拓展我们公司当前的药物滥用检测的应用范围。”

Test to Detect Drugs of Abuse in ED
 
A new point-of-care (POC) test is a rapid in vitro diagnostic test to determine if patients entering the emergency department (ED) of a hospital are under the influence of drugs of abuse.

The OnTrak TesTcard 9 provides a qualitative screen for the presence of amphetamines, barbiturates, benzodiazepines, cocaine, methamphetamines, morphine, phencyclidine (PCP), tetrahydrocannabinol (THC), and tricyclic antidepressants (TCA) in urine. The single-step test requires no reagent mixing, timing, incubation, or special handling. Results for all nine drugs are available in three to five minutes, which the developer notes is three times faster than competitive tests. In addition, test results are stable for up to six hours.

The test is the product of Varian, Inc. (Palo Alto, CA, USA). “TesTcard 9 affords us the opportunity to expand our point-of-care tests beyond criminal justice and workplace applications by opening the doors to clinical applications,” stated Stephen Schultheis, vice president and general manager, consumable products, Varian. “This clinical POC application is an exciting new opportunity for Varian as we assess future developments with products and new technologies which will move us further outside our current drugs-of-abuse applications.”
