Answer 1: The maximum time between a sample being produced by the patient and put into the OMNImet- GUT or OMNIgene-GUT tube is 4 hours. So if it's been sitting in a diaper for more than 4 hours the sample can't be used. Once the sample is in the sample tubes (and shaken x 30 seconds) it is stable at room temp, +4, or -20 for 72 hours. It needs to be then placed in -80C until batched for shipping to our main study site. The sample tubes can also be immediately put into a -80C freezer if you have that available.
