USPS Deliveries May Be Affected Due To Exceptionally High Volumes and Covid-19 Pandemic

Some customers may experience slightly longer delivery timescales than normal. The USPS has confirmed “exceptionally high volumes” of post this spring, so please expect an extra 2 to 7 days for delivery of the Testing Kit and processing of your fur sample.

All received test submissions are processed promptly with results emailed within 3 working days of receipt.

We apologize for the delay and thank you for your patience during this difficult time.
