Does the sample collected with the Teal Wand expire?

The stability of your sample while it is on the way to the lab has been tested for a specified period of time, which is why you should mail your sample via the US Postal Service (USPS) within 24 hours of collecting it.

The lab must receive your sample within a specified timeframe in order to process it. This window of time starts from when you collect your sample and includes all time in the mail before getting to the lab. That is why we recommend you mail your sample within 24 hours, so that even if there are shipping delays, your sample will be able to be processed at the lab.

We suggest not screening on days the USPS is closed, such as Sundays and holidays. You can mail your sample in your home mailbox (if it fits), drop it off at the Post Office, or schedule a USPS pickup
