Shipping a sample

The Minnesota Urolith Center does not provide containers or prepaid mailers. Any shipping, duties, or customs inspection charges are the responsibility of the shipper. Domestic samples can be shipped via US Mail or through your preferred shipper.

Sending specimens by a carrier that provides tracking will minimize transit delays. If shipping through the US Postal Service make sure sufficient postage is affixed. Postage is calculated by weight and parcel size.

To confirm that the sample was received, check back into your account on our online laboratory and select “search” in the top navigation bar. This page will list the status of all samples under your clinic account. For further assistance, view the printable guide with images, visit our FAQ page or contact us at


  • Print out the packing slip and address label. Verify that owner/patient names on specimen container and paperwork match.
    • If you notice an error, write the correction on the submission form. We will correct the data when we receive the sample.


  • Place the specimen container in a plastic bag, use one staple to attach bag to the back of the submission form -or- use a two pouch plastic bag. Place the sample in the Ziploc portion. Place the folded submission form in the outer pocket with the barcode facing out.


  • Use paper envelopes.  Plastic or glass vials may not withstand shipping in a paper envelope.
  • Rubber band the submission form around the vial. It impedes sample processing and document scanning.
  • Place the submission form inside the vial. Samples can be lost when we retrieve the form.
  • Submit samples labeled with the biohazard symbol because regulations require special handling and disposal of these samples.


  • Place the sealed plastic bag containing the specimen vial, packing slip, and packing material in a sturdy outer box.


  • Secure with packing tape. Adhere the address label (second page of packing slip) to the outside of the package if needed
