How to Mail a Spore Test

This article offers practical tips and tricks to help you mail your samples efficiently, ensuring your tests arrive at our lab as quickly and smoothly as possible. From correctly labeling your testing envelopes, to understanding optimal shipping timelines, you’ll learn simple steps that make a big difference in turnaround time.

Prepare Your Envelope:

Fill out the test date and operator on the back of your envelope.
Include the sterilizer Make, Model, and Serial number if not already provided.

Add Your Return Address:

● On the top left corner on the front of the envelope, write your name and address. This is
important in case the letter cannot be delivered and needs to be returned to you.
● Do not write your address anywhere other than the top left corner. Placing your address
on the wrong side of the envelope may result in your test being returned.

Affix Postage:

● Affix a first class stamp to the top right corner on the front of the envelope.
Send the Letter:
● Place your letter in the mailbox or take it to the post office.
Additional Services:
● If you require tracking, certified mail, or delivery confirmation, inquire about these options
at the post office

Please allow one week for delivery using USPS First Class Mail. If you need to rush your
test to us, you can use an expedited service. If shipping via UPS or FedEx, your test must be
shipped to our street address:
