| 520 | 3 | |a Participants taking part in proficiency testing (PT) schemes often question whether the transport conditions, particularly time and temperature, could affect their sample and subsequently their performance scores. This is particularly true for microbiology PT schemes which contain living microorganisms and therefore pose a significant challenge in maintaining stability during a range of different transport conditions. Even though the PT provider can perform stability testing, it is impossible to predict and reproduce all possible environmental conditions that samples could be exposed to during transport. In this study, a number of PT scheme samples were selected in order to observe the effects of transport on the participant results for a range of different microorganisms and matrices. For each microorganism over a number of rounds, the participant results were compared against date of analysis, average distance travelled (km) and average temperature (°C) of destination country in order to determine whether there were any significant trends between participants' results and the different transport conditions. More than half of participants (62%) received and tested the PT samples within 4days of the dispatch date, and 90% of participants received and tested the samples within 10days of the dispatch date. Distance travelled by samples ranged from 0 to 16000km, and the average temperature of destination countries ranged from -10°C to +25°C. The results varied by round and microorganism, but overall the date of analysis, distance travelled and average temperature of destination country were not found to have a significant effect on participant results. Even participants from the same country receiving and testing the same sample at the same time could obtain very different results which are therefore unlikely to be due to transport factors. | |
