Shipping Alternative: Using Traditional Postal Services

If you are unable to reach a UPS Dropoff location or if the nearest point is inconveniently far, you have the option to ship your test sample using your local traditional postal service at your own cost.

Follow these steps for shipping via postal mail:

1. Prepare the Shipment: Ensure your test sample is sealed securely in the provided shipping materials, just as you would for the UPS dropoff.
2. Determine Cost and Service:
   • Visit your local post office or their website to calculate the appropriate postage.
   • Crucially, use a service that provides a tracking number (e.g., Registered Mail, Priority Mail, or a similar tracked option). This is essential for confirming safe delivery to the lab.
3. Address the Package: Clearly affix the provided lab address label onto the package.
   • If you do not have a pre-printed label, confirm the exact shipping address with the lab or through the kit instructions.
4. Mail the Sample: Drop off the package at your local post office.
5. Record the Tracking: Immediately record the tracking number provided by the postal service. You may need this to confirm delivery or inquire about the package status.
