Rates for shipping vary depending on what carrier and service you use, shipping distance, and the number of kits being sent. You will need to check with your carrier for accurate pricing. Please note that we must receive your kit within 10 days of being stopped for best results; after that time period, we cannot guarantee a valid reading.

  • We do offer return shipping via FedEx SmartPost! FedEx has been one of the most reliable carriers we’ve worked with and their SmartPost service is affordable and easy to use. For more, visit our webpage!
  • We strongly recommend purchasing a service that includes tracking. This is the best way to ensure delivery to our labs and to know whether or not we have received it!
  • Recently, USPS has increased the amount of postage needed for First Class mail (using stamps). Some older tests may contain outdated information, so be sure that you are using the correct amount of postage! For the current postal rates, click here.

We do not recommend shipping with USPS First Class (using stamps) as they are the least reliable carrier. We also advise placing your kit(s) inside another shipping box or envelope for extra protection during shipping!
