Great question! After you post your samples (using the enclosed pre-paid envelope), the Royal Mail typically delivers your samples to our lab in 1-2 business days.
We'll be sure to send you an email the same day the Royal Mail delivers your samples, and we'll start analysis right away.
In the event the Royal Mail experiences a delay, don't worry: we'll first test your samples to make sure they are still valid before testing, to ensure maximum accuracy.
