The assay relies 100 ng/ml of oxycodone on the competition for binding antibody. When drug is present in the THC Cannabinoid (THC) 50 ng/ml of 11-nor-9-THC-9-COOH urine specimen, it competes with drug conjugate for the limited amount of 200 ng/ml of Tramadol antibody-dye conjugate. When the amount of drug is equal or more than the cut-off, it will prevent the binding of drug conjugate to the antibody. NB. Dipscan 10 Plus is set to the AS/NZS 4308 Australian/New Zealand

Methamphetamine is the most popular synthetic derivative of the amphetamines.

Amphetamines are central nervous stimulants that cause the of increased energy and power. More acute response produces anxiety, neutrotransmitters epinephrine, norepinephrine and dopamine to be released paranoia, psychotic behavior, and cardiac dysrhythmias. Methamphetamine into the brain and body giving users feelings of euphoria, alertness, and is excreted in the urine as amphetamine and oxized and deaminated increased energy. Chronic abuse of amphetamines leads to tolerance and drug derivatives. However, 10-40% of methamphetamine is excreted unchanged. reinforcement effect. Cardiovascular responses to amphetamine include increased Methamphetamine is generally detectable in the urine for 3 to 5 days after blood pressure and cardiac arrhythmias. More acute responses produce anxiety, paranoia, hallucinations and psychotic behavior. Amphetamines are metabolised Opiate (OPI)
by a number of pathways. In general, acid urine promotes excretion whereas alkaline urine retards it. In 24 hours, approximately 79% of the amphetamine Opioid analgesics comprised of a large group of substances that control pain dose is excreted in acid urine and about 45% in alkaline urine. Typically, about by depressing the central nervous system. Acute high dose used by abusers 20% is excreted as unchanged amphetamine.

Benzodiazepines are a class of widely prescribed central nervous system depressants which have anxiolytic, hypnotic, anticonvulsant and muscle relaxant effects. Chronic abuse can result in addiction and tardive Oxycodone is known as Oxycontin, Roxicodone and is an ingredient of dyskinnesia. Acute higher doses lead to drowsiness, dizziness, muscle Percodan, Percocet, Roxicet and Tylox. Oxycodone is a semi-synthetic relaxation, lethargy, coma and possible death. The effects of benzodiazepines opiate derived from opium. Like other opiates, oxycodone is characterized use last 4 – 8 hours. Many of the benzodiazepines share a common metabolic by its analegestic properties, and the tendency for users to form a physical route, and are excreted as oxazepam and its glucuronide in urine.

usually administered in combination with non-opiate analegesics such as acetaminophen and salicylates for the relief of moderate to severe pain. Oxycodone is a central nervous system depressant that may cause drowsiness, A derivative of thebaine, buprenorphine is an opioid that resembles dizziness, lethargy, weakness and confusion. Toxicity in an overdose of morphine structurally but has a longer duration of action than morphine oxycodone can lead to stupor, coma, muscle flaccidity, severe respiratory and can be administrated sublingually as an analgesic.

Marijuana (THC )
The agents of Marijuana that cause various biological effects in humans are Derived from the leaves of cocoa plant, cocaine is a potent central nervous called cannabinoid. Cannabinoid is a central nervous stimulant that alters system stimulant as well as a local anesthetic. Some of the psychological mood and sensory perceptions, produces loss of coordination, impairs short effects induced by cocaine are: euphoria, confidence and a sense of increased term memory, and produces symptoms of anxiety, paranoia, depression, energy, accompanied by increased heart rate, dilation of the pupils, fever, confusion, hallucination, and increased heart rate. Large doses of cannabinoid tremors and sweating. Continued ingestion of cocaine could induce could cause the development of tolerances and physiological dependency tolerances and physiological dependency which leads to its abuse. Cocaine is and lead to abuse. A tolerance to the cardiac and psychotropic effects can used by smoking, intravenous, intranasal or oral administration and excreted occur and withdrawal syndrome produces restlessness, insomnia, anorexia in the urine primarily as benzoylecgonine in a short period. Benzoylecgonine and nausea. Δ9-THC is the primary active ingredient in cannabinoids. The has a biological half-life of 5 – 8 hours, which is much longer than that of main metabolite excreted in the urine is 11-nor- Δ 9-THC-9-COOH, which cocaine (0.5 – 1.5 hours), and can be generally detected for 12 – 72 hours are found within hours of exposure and remain detectable in the urine for after cocaine use or exposure. 10-30 days after smoking, longer for chronic users.
Methadone is a synthetic opioid, clinically available. It is used clinically for Tramadol is a quasi-narcotic analgesic used in the treatment of moderate the treatment of severe pain and in maintenance programs for morphine and to severe pain. It is a synthetic analog of codeine, but has a low binding heroine addicts. Methadone acts on the central nervous and cardiovascular affinity to the mu-opioid receptors. Large doses of tramadol can develop tolerance and physiological dependency and lead to its abuse. Tramadol is GC/MS at a cut-off of 300 ng/ml of benzoylecgonine.
