How long are my saliva samples viable for? Updated 2 years ago

Saliva samples are viable for up to 30 days. *We highly recommend sending your sample right away if possible to make sure the sample reaches the lab with plenty of time. If you cannot send right away, we recommend freezing the saliva sample and making sure the blood spot sample is stored in a cool, dry area away from light (may place in the fridge if needed).
