Preparing a sample

To prepare a sample for shipment and analysis follow the steps below.

  • Rinse uroliths gently in water and air dry. Samples must be dry before shipping.
  • Do not send in formalin or any liquid. These require special handling and will delay processing.
  • Place clean dry uroliths in a labeled, non-breakable container such as a clean plastic vial, ziploc bag, or whirl pac bag.
  • Label specimen container with the owner/patient name.
  • Login at and enter the patient/sample information.
