Des Plaines, IL - United States Drug Testing Laboratory, Inc. (USDTL), a forensic laboratory specializing in drug and alcohol testing using advanced specimens, has released a new assay to detect zolpidem (Ambien®) use in fingernail and hair specimens. Previously available only in urine and oral-fluid specimens, zolpidem testing in fingernails and hair offers forensic drug testing professionals new, powerful tools to meet their drug testing needs.
Since its approval in 1993 for the treatment of insomnia, zolpidem has become one of the most popular and most prescribed sleep aids. Zolpidem is a sedative-hypnotic medication that affects the same areas of the brain as benzodiazepines. In 2011, 39 million prescriptions for zolpidem products were written in the United States. 
Zolpidem use carries some risks of harm, especially when taken in combination with other substances. The number of emergency department visits related to zolpidem grew by 136% from 2004 (12,792) to 2011 (30,149).  Other substances were involved in 57% of those ED visits, including benzodiazepines (26%), narcotic pain relievers (25%), and alcohol (14%). 
The development of zolpidem testing is driven by USDTL’s ongoing commitment to be a leader in substance abuse and alcohol detection. Zolpidem testing in fingernails and hair will be available on October 1st, 2014.
USDTL has made significant breakthroughs in detecting alcohol and other substances of abuse. They offer a wide range of testing services and specialize in hard to detect substances of abuse, customized assays, and advanced drug testing specimens.

On August 18, 2014, the pain reliever tramadol (Ultram®) will be scheduled as a Class IV controlled substance by the U.S. Drug Enforcement Administration.1 Tramadol is a synthetic, opioid pain reliever similar in strength to codeine. In 2012, more than 40 million tramadol prescriptions were written in the United States, more than any other opioid medications except for hydrocodone and oxycodone.2
In 1994, clinical data suggested tramadol had a very low abuse potential.3 Research has since shown that tramadol can produce a euphoric high similar to oxycodone. At doses greater than prescription levels, tramadol has addiction reinforcing effects similar to morphine and oxycodone.
Between 2004-2012, emergency department visits related to illicit tramadol use increased from 4,800 incidents to more than 16,000.1 Adverse effects of tramadol include sedation, dizziness, respiratory depression, seizures, apnea, and death.4
Withdrawal symptoms often occur following both abrupt and tapered discontinuation of tramadol use, suggesting an issue of drug dependence for tramadol users.
In the year 2000, tramadol was present in only 82 law enforcement drug seizures. This number increased to 1806 by 2012.1 A 2002 study found that 87 out of 140 healthcare professionals testing positive for tramadol use obtained the drug with illegal prescriptions.
Tramadol is available in both single dose (25-100 mg) and extended release (100-300 mg) forms. Tramadol abusers can crush extended release tablets and ingest them for an instant, high-dose euphoria similar to OxyContin but without the cognitive impairment.2
Fingernail testing detects tramadol use for up to six months, while hair provides a three month look-back. Tramadol testing is available in USDTL’s extended drug panels.
