Introduction

An important element of the UNODC International Quality Assurance Programme (IQAP) is the implementation of the International Collaborative Exercises (ICE). The exercises allow laboratories, from both developing and developed countries, to continuously monitor their performance in testing on a truly global scale. Two rounds are offered per year with each round presenting participants with four different test samples for analysis.

This report provides information on the analytical results of laboratories participating in the Biological Specimens (BS) group. In order to maintain confidentiality, the participating laboratories have been assigned random “Web Codes”, which change every round. The analytical results returned by laboratories participating in ICE are evaluated by UNODC and a confidential report is provided to each laboratory on its own performance. Analytical results are reviewed by the UNODC’s International Panel of Forensic Experts which oversees the implementation of these exercises, and offers guidance and support in addressing relevant quality issues. The exercises provide an overview of the performance and capacity of participating laboratories and enable UNODC to tailor technical support in the laboratory sector for greatest impact.

Comments from the International Panel of Forensic Experts

Participation of laboratories

Samples within both the Seized Materials (SM) and Biological Specimens (BS) test group were sent to 167 laboratories in 55 countries. 68 laboratories in participated in the BS test group and 62 (91%) laboratories submitted the results of their analysis in time for inclusion in the summary report, with 97% using the ICE portal for return of results. The almost universal usage of the ICE portal continues to be a high endorsement of its utility.

Qualitative and Quantitative Analysis of the biological specimens test samples

Overall, the level of performance in identification of the test samples was good given the inherently higher level of difficulty in the analysis of biological specimens compared to seized materials. BS-1 contained amfetamine and 85% of participants identified the substance while there were two false positives for controlled substances (MDEA and metamfetamine). BS-2 contained 11-nor-∆9-THC-9-carboxylic acid, which was identified by 89% of participants and there were no false positive results reported for this test sample. BS-3 contained Morphine and this was identified by 89% of participants. There were a number of false positive results for this test sample, including four for morphine glucuronides, three for and one each for 6-monoacetylmorphine and 11-nor-∆9-THC-9-carboxylic acid. BS-4 contained a mixture of two metabolites, benzoylecgonine and methylecgonine. The former was identified by 85% of participants, while 60% identifed the latter. Within BS-4, there was one false positive result for 11-nor-∆9-THC-9-carboxylic acid. With regard to false negative results, there were seven for BS-1, two for BS-2 and BS-3, six for benzoylecgonine in BS-4 and 11 for methylecgonine in BS-4.

The results for quantitative analysis within the BS test group were excellent with 23 of 25 (92%, BS-1), 28 of 28 (100%, BS-2), 25 of 26 (96%, BS-3,) 25 of 25 (100%, BS-4, benzoylecgonine) and 11 of 15 (73%, BS-4, methylecgonine) participants performing quantification with acceptable Z-scores less than 3.5 (A modified Z-score was used for the statistical examination of the quantitative results, as it is a robust method based on absolute deviations from the median of all participant values and is relatively insensitive to outliers). It is encouraging to note that of those laboratories who did carry out quantification, 67% (22 of 31) performed quantification of at least one substance in all test samples. The predominant analytical techniques used by participants for quantifaction within the BS test group were GC/MS (83%) followed by LC/MS (8%) and others at (9%).

Laboratories are encouraged to carry out quantification as it can improve the quality of laboratory analyses and can be helpful in assessing the significance of the results. Also, laboratories reporting false positive or false negative results should investigate the reasons for this and corrective actions should be taken in order to continuously improve performance. Participation in ICE also helps in monitoring the effect of corrective actions.

Z-Score has been calculated as modified Z-Score as it is a robust method and therefore relatively insensitive to outliers. Modified Z-Score = 0.6745 * AbsDev/MAD AbsDev = Absolute value of the difference between a laboratory value and the median of all the laboratory values for the given drug; MAD = median absolute deviation about the median.
