Most of the samples are stable from 4 to 8 days so there is enough time to get them to the lab. Some samples do have to be delivered overnight and we have taken care that this process goes smoothly. You will get detailed instructions how to prepare the samples and when to call the courier to pick them up. From then on, we will take care that the samples are delivered correctly and on time.
In the case of urine only DUTCH tests you will send the samples on your own as they are stable for at least 21 days and can be shipped in a regular envelope.
