Abstract
Publisher Summary
This chapter discusses the use of separation methods for the isolation, identification, and quantitative analysis of natural and synthetic opiates. The term “opiate” refers specifically to the products derived from the opium poppy. The chapter describes morphine derivatives and synthetic or semisynthetic opiates, showing agonistic action at opioid receptors OP1 (δ), OP2 (κ) or OP3 (μ). Preliminary testing for the opiates in field conditions is mainly performed by law-enforcement officers (police, prison, or customs officers). The testing devices are simple and robust and usually based on well-known color reactions. The main purpose of these tests is to select suspicious samples or materials for possible further examination with confirmatory methods. Preliminary methods used for biological fluids may be divided according to different criteria. From the technical point of view, these methods are divided into onsite and laboratory tests. These two groups of tests are discussed in the chapter in detail. Immunoassays are the most important techniques used for the preliminary testing of opiate agonists. The trend toward the use of immunoassays for alternative samples available in a noninvasive way—for example, saliva or sweat—is described in the chapter.
1.1 Introduction
In this chapter, the use of separation methods for the isolation, identification, and quantitative analysis of natural and synthetic opiates is reviewed. Strictly speaking, the term “opiate” refers specifically to the products derived from the opium poppy. The review focuses on morphine derivatives and synthetic or semisynthetic opiates, showing agonistic action at opioid receptors OP1 (δ), OP2 (κ) or OP3 (μ). The action of opiates on opioid receptors has been reviewed elsewhere [1,2]. The present overview focuses on forensic analytical applications, devoted mainly to biological samples. These applications are divided into several sub-chapters, convering:
In each sub-chapter the relevant separation techniques: thin layer chromatography (TLC), gas chromatography (GC), high-performance liquid chromatography (HPLC), and capillary electrophoresis (CE), combined with various detection methods, are reviewed in turn.
1.2 Preliminary methods for opiate detection
Preliminary tests play a dual role in forensic toxicology. First of all their use fulfills the main condition of forensic analysis, i.e. the application of two independent methods for positive results whenever possible. The second purpose of these tests is to exclude samples that definetly do not contain any opiates. Since a negative result from a preliminary test is usually decisive, there is no room for false-negative results. Therefore, preliminary tests should show broad group specificity and possibly high sensitivity, whereas an absolute specificity is not required. An unequivocal identification and quantitation is usually carried out in the confirmatory step of analysis.
1.2.1 Methods used for street drugs
Preliminary testing in field conditions is mainly performed by law enforcement officers (police, prison, or customs officers). The testing devices are simple and robust, and usually based on well-known color reactions. The main task of these tests is to select suspicious samples or materials for possible further examination with confirmatory methods.
Narcopouch® (ODV Inc., Paris, ME, USA) is a battery of color tests for the detection of opiates, amphetamines, cocaine, barbiturates, cannabinoids, and lysergic acid diethylamide (LSD) in street samples. This test uses color reactions with several reagents, e.g. Marquis, Meyer’s, Mecke, Ehrlich’s, Fast Blue B, and Koppanyi. The whole procedure is performed in a plastic pouch by visual inspection. The Herosol® (Mistral Detection Ltd., Jerusalem, Israel) field kit consists of a spray reagent and special test paper. A suspected surface (e.g. skin) is wiped with the paper, which is then sprayed with Herosol. A violet color indicates the presence of heroin. A similar heroin test Detect Now™ is supplied by Test Medical Symptoms@Home, Inc., and is marketed via the internet as a simple test for parents who want to check their children for drug use. The NIK® (Public Safety Inc., Armor Holding, Jacksonville, FL, USA) narcotic field test consists of individual ampoule tests for the main groups of drugs of abuse, among them opiates/amphetamines, and heroin/opium. Drug Wipe and Drug Wipe II (Securetec AG, Germany) are immunochemical tests designed for the detection of drugs of abuse on different surfaces, e.g. luggage, passports, currency, and also on the skin or the tongue. Therefore, these tests may be used for the detection of drugs in sweat or saliva. The detection limit for opiates is 25 ng of morphine equivalent. With a portable reader a colorimetric quantitation may be performed.
1.2.2 Methods used for biological fluids
Preliminary methods used for biological fluids may be divided according to different criteria. From the technical point of view, it is obvious to divide these methods into on-site and laboratory tests. These two groups of tests are discussed below. However, preliminary tests may be used not only for forensic or preventive purposes, e.g. in employee screening, but also as a diagnostic procedure in suspected acute poisoning. In on-site tests applied in a clinical emergency ward, the confirmation analysis sometimes is not of primary importance. In the case of a suspected heroin overdose, the positive result of a preliminary opiate test is an indication for the administration of an opiate antagonist, e.g. naloxone, instead of waiting for the results of the confirmatory analysis. This practice is not limited to health professionals; the distribution of naloxone for administration in addicts’ home by their companions or family members is a novel approach, which is being tested in the USA, Germany, and the UK [3].
1.2.2.1 On-site tests
There is a multitude of socially critical situations that demand full sobriety and an unaffected psychomotorical condition. On-site tests are widely used among very different social groups, including automobile drivers, incarcerated criminals, the military, athletes, employees of the oil industry, and others. The particular value of the on-site test is in the testing of mobile groups located in remote areas. The most important is the ability to use non-invasive sampling. For this reason, testing of saliva or sweat instead of urine or blood has become particularly attractive. It should be added that on-site tests might also be very valuable in monitoring some therapeutic drugs. For these reasons, such tests carry an alternative name of “point-of-care tests”. Jenkins and Goldberger published a comprehensive review of on-site drug testing, comprising all aspects of this technique [4]. Table 1.1 shows some popular on-site testing devices used for opiate detection. All these tests use the immunoassay principle and are capable of detecting the whole panel of drugs of abuse, including amphetamines, benzodiazepine, cannabinoids, cocaine, and opiates.
Table 1.1 On-site tests used for opiate detection
Crouch et al.[5] performed a field evaluation of five on-site drug-testing devices: AccuSign, Rapid Drug Screen, TesT-Cup-5, TesTstik, and Triage. Four hundred urine samples were collected and tested at two sites. All positive results were confirmed using gas chromatography-mass spectrometry (GC-MS; for morphine and codeine) or liquid chromatography-mass spectrometry (LC-MS; for hydrocodone and hydromorphone). One false-negative result was observed. The false-positive rate was below 0.25% for all devices. Gronholm and Lillsunde [6] evaluated eight on-site devices for urine and oral fluid assay of opiates and other drugs. In the case of opiates, the accuracy ranged from 94 to 98% for both matrices. In a multicenter evaluation of the immunochromatographic on-site urine test Frontline® published by Wennig et al.[7], the sensitivity and specificity for opiates was above 99% for all centers involved. Buchan et al.[8] evaluated the accuracy and specificity of four on-site kits for urine testing. Opiates were correctly detected in 100% of cases by all the kits.
Barrett et al.[9] evaluated an ORALscreen System for the on-site analysis of drugs in oral fluids and found very good agreement with laboratory-based urine screening test results for...
