How do I know if my test includes prepaid return shipping?
First Alert, Kidde, and LabTech brand test kits do not include prepaid return shipping. For all other kits, check for either an included prepaid return shipping label or prepaid USPS First Class Postage on your return mailer:
- If your test includes a 4″x6″ return shipping label sticker, your test includes prepaid return shipping. Follow the instructions provided with the shipping label. In general, you should seal each test individually in the provided return mailer. Next, place all test kits in one box or package and apply the label to the box or package. If you are shipping just one test, you can apply the label to the back of the mailer.
- For FedEx return shipping labels, you must drop the package off at a FedEx location. Use this link to find a FedEx location. We recommend getting a receipt when you drop off your package; this ensures FedEx has properly processed the package.
- For USPS return shipping labels, you can put the package in your mailbox or drop it off at any USPS location.
- Some older tests include prepaid USPS First Class Postage. If your return mailer says “NO POSTAGE NECESSARY IF MAILED INSIDE THE UNITED STATES” in the upper right corner, your test already includes prepaid USPS First Class Postage, and no stamps or shipping label is necessary. To use the prepaid postage, ship each test individually in the provided return mailer.
Please understand that we cannot guarantee USPS will deliver your test kit within the 10-day window. Customers who ship via USPS First Class do so at their own risk.
What are some additional tips for shipping my sampler back to the lab?
- Ship your test kits promptly. Delays may invalidate your test.
- Keep a copy of your shipment tracking information. You can use this to track the shipment delivery to the lab. Shipping time is the biggest factor in analysis time; our lab’s analysis time is typically 3-5 business days (faster if you purchase Lab Rush service).
- Keep a copy of your Test Kit Serial # in case you need to contact us.
- Ship all your tests in one box or package so they arrive at the same time. Make sure each test is sealed individually in its own mailer to prevent cross contamination.
- Plan to stop your test early in the week (not on a weekend). Most shipping companies don’t operate on weekends, so it’s best to ship the test early in the week when possible.
- Avoid testing near holidays when possible. Shipping companies don’t operate on some holidays which will increase shipping times.
