Specimen Collection

Special Instructions

N/A

Preferred Specimen

Dry stone(s) collected in a sterile screw-cap container

Minimum Volume

N/A

Instructions

  1. Clean any blood or foreign material from the stone with water.
  2. Stone should be air dried thoroughly at room temperature for approximately 24 hours. A dry stone should not stick to the walls of the plastic container.
  3. Important: Do not tape specimen; Do not send stone in formalin, surgical gel, or any transport  media; Avoid sending filters and cotton swabs (Q-tips)
  4. Additional processing is required for stones received with residual liquid or dampness, potentially causing delays in testing.
  5. In cases for multiple stones that require individual analysis, testing must be ordered for each stone and will be charged separately. Each stone should be placed in its own plastic container.
  6. Indicate source of specimen on outside of container (e.g., left kidney, bladder, right ureter).
