![]() Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. This assay provides only a preliminary analytical test result. The results are summarized below.Ĭonfigurations of the One Step -Drug Screen Test Card consists of combination of Cocaine, Amphetamine, Marijuana(THC), Methamphetamine, Opiate drug analytes. This is the suggested screening cut-off for positive specimens set by the Substance Abuse and Mental Health Services Administration (SAMHSA, USA).Ī drug-free urine pool was spiked with drugs at concentrations listed. The One Step Drug Screen Test Card yields a positive result when the morphine in urine exceeds 2,000 ng/mL. The One Step Drug Screen Test Card yields a positive result when the Methamphetamine in urine exceeds 1,000 ng/mL. Methamphetamine is generally detectable in the urine for 3-5 days, depending on urine pH level. Thus, the presence of the parent compound in the urine indicates Methamphetamine use. However, 10-20% of Methamphetamine is excreted unchanged. Methamphetamine is excreted in the urine as amphetamine and oxidized and deaminated derivatives. The effects of Methamphetamine generally last 2-4 hours and the drug has a half-life of 9-24 hours in the body. More acute responses produce anxiety, paranoia, hallucinations, psychotic behavior, and eventually, depression and exhaustion. Cardiovascular responses to Methamphetamine include increased blood pressure and cardiac arrhythmias. Acute higher doses lead to enhanced stimulation of the central nervous system and induce euphoria, alertness, reduced appetite, and a sense of increased energy and power. The drug can be taken orally, injected, or inhaled. Methamphetamine is made in illegal laboratories and has a high potential for abuse and dependence. Methamphetamine is closely related chemically to amphetamine, but the central nervous system effects of Methamphetamine are greater. Methamphetamine is an addictive stimulant drug that strongly activates certain systems in the brain. Elevated levels of urinary metabolites are found within hours of exposure and remain detectable for 3-10 days after smoking. The peak effect of marijuana administered by smoking occurs in 20-30 minutes and the duration is 90-120 minutes after one cigarette. Long-term, relatively heavy use may be associated with behavioral disorders. They may also experience transient episodes of confusion and anxiety. ![]() Users have impaired short term memory and slow learning. When smoked or orally administered, THC produces euphoric effects. ![]() THC (∆9-tetrahydrocannabinol) is the primary active ingredient in cannabis (marijuana). They are chemically related to the human body’s natural catecholamines: epinephrine and norepinephrine. Amphetamines are a class of potent sympathomimetic agents with therapeutic applications. It is excreted in the urine in a short time primarily as Benzoylecgonine.Īmphetamine is a Schedule II controlled substance available by prescription (Dexedrine®) and is also available on the illicit market. Cocaine is often self-administered by nasal inhalation, intravenous injection and free-base smoking. In large amounts, cocaine causes fever, unresponsiveness, difficulty in breathing and unconsciousness. Initially, it brings about extreme energy and restlessness while gradually resulting in tremors, over-sensitivity and spasms. ![]() The One Step Drug Screen Test Card is a lateral flow chromatographic immunoassay for the qualitative detection of multiple drugs such as Cocaine, Amphetamine, Marijuana(THC), Opiates, Phencyclidine and drug metabolites in urine at the following cut-off concentrations: TestĬocaine is a potent central nervous system (CNS) stimulant and a local anesthetic. ![]()
