We would like to reassure you that we are maintaining our activities. However, in order to contribute to the efforts of the Government of Quebec to limit the transmission of COVID-19, we would appreciate that you prioritize your requests and it is possible that there may be an additional delay before sending results. This is particularly important for requests for necropsy, as well as requests for samples from research projects sent in large numbers.
We also ask you to call with us before taking sample for a referred test, as we will need to check the availability of service from the laboratory of destination.
