一種新型床邊檢測方法是一種快速體外診斷檢查，能夠確定醫(yī)院急診科就診的患者是否受到了藥物濫用的影響。

OnTrak TesTcard 9能夠定性篩查下述尿液中的藥物：安非他明、巴比妥酸鹽、苯二氮、可卡因、脫氧麻黃堿、嗎啡、苯環(huán)己哌啶、四氫大麻酚、三環(huán)抗抑郁藥。這種一步法檢測不需要對試劑進(jìn)行混合、定時、孵育或者特殊處理。對這九種藥物的檢測結(jié)果在3~5分鐘之內(nèi)就可以得出，開發(fā)商聲稱比同類競爭產(chǎn)品快3倍。除此之外，這些檢測結(jié)果在長達(dá)6小時的時間內(nèi)保持穩(wěn)定。

這種檢測方法是美國Varian公司的產(chǎn)品。Varian公司消費(fèi)產(chǎn)品部副總裁兼總經(jīng)理Stephen Schultheis指出：“TesTcard 9為我們提供機(jī)會，將我們的床邊診斷產(chǎn)品從犯罪鑒定和現(xiàn)場應(yīng)用擴(kuò)大到了臨床應(yīng)用。這種臨床POC應(yīng)用對Varian公司而言是一種令人鼓舞的新機(jī)會，因?yàn)槲覀兛梢栽u估產(chǎn)品和新技術(shù)未來的發(fā)展，這將會為拓展我們公司當(dāng)前的藥物濫用檢測的應(yīng)用范圍。”

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.”
