On the other hand, EtG in meconium is more stable at room temperature and its levels in meconium have been better correlated with EtG levels in maternal hair and with maternal self-report than FAEEs in meconium [118]. We present a series of 29 necropsies in which organic compounds (including benzodiazepines, barbiturates, antidepressants, phenothiazine, opiates, cannabinoids . Open navigation menu. Volume of collected sample is also dependent on both internal (inter- and intra-variability in sweat production) and external factors (physical exercise, room temperature, etc.) However, direct immunoassays such as radioimmune analysis and enzyme-linked immunosorbent assay (ELISA) can also be performed in this matrix [76], although confirmatory analysis relying on traditional techniques may be required. The main mechanisms by which drugs pass from blood into the oral fluid are the passive diffusion (hydrophobic compounds) and ultrafiltration (low molecular hydrophilic substances) [11]. However, due to inherent characteristics and toxicokinetics, drug levels in some of these matrices may be reduced in comparison to blood or urine. J Anal Toxicol 39:225228. Anal Bioanal Chem 397:10391067. The perspective in forensic toxicology is that alternative matrices will be more frequently explored in the future. Multi-step SPE column preparation and multiple extractions add to turn-around-time creating a bottle-neck in sample throughput for laboratories. https://doi.org/10.1111/j.1530-0277.2012.01763.x, Walker A (2010) Breast milk as the gold standard for protective nutrients.

The utilization of insects as an alternative matrix for drug identification is well-reported and suggested without conventional matrices for example urine, blood, or internal organs. However, theses matrices have also limitations such as limited incorporation of drugs (according to physicalchemical properties), impossibility to correlate the concentrations for effects, low levels of xenobiotics and ultimately the need for more sensitive analysis. https://doi.org/10.1093/jat/bkz048(open access article), Khurshid Z, Zohaib S, Najeeb S, Zafar MS, Slowey PD, Almas K (2016) Human saliva collection devices for proteomics: an update. https://doi.org/10.1016/j.forsciint.2006.05.004, Wjtowicz A, Wietecha-Posuszny R, Snamina M (2020) Contemporary trends in drug analysis of vitreous humor: a critical review. The application of forensic entomotoxicology in investigations of death by poisoning has gained popularity as insects serves as an alternative specimen (evidence) when conventional toxicological samples have degraded or are no longer available.

Water or saline solution may be used as surrogate for VH, to provide the physical aspect of the eyeball, after VH is removed [153, 161], especially for funeral purposes. Another study involving the controlled intake of 3,4-methylenedioxymethamphetamine (MDMA) indicated that the parent drug was the main detected analyte, positive in 59.7% of the samples, at<3007ng/patch.

Unlike EtG, FAEEs from mother do not across the placenta and thus FAEEs in meconium are produced by the fetus from ethanol that crossed the placenta, reflecting the true fetal alcohol exposure [117]. The most accepted model assumes that drugs and their metabolites are incorporated in hair by passive diffusion through blood capillaries to the cells of the growing matrix, at the base of the hair follicle.

On the other hand, this method allows prompt collection of sweat and standard sample volumes can be used for the following analysis [77]. A false negative result may be due to instability of some analytes in meconium (e.g., FAEEs, 6-MAM); inappropriately high cut-off concentration; delayed meconium collection (collected sample is transition stool or milk stool); inappropriate analytical targets (analytes not common in urine can improve detection of drug in meconium, e.g., m-hydroxybenzoylecgonine and p-hydroxymethamphetamine) [110, 123].
