Note
Detailed collection instructions are available in the Renal Biopsy Collection Kit (#40460) or can be requested by contacting ARUP Client Services at (800) 522-2787. Use of a different collection kit could result in suboptimal biopsy fixation and delays in diagnosis. To ensure timely result reporting, include with the test order: nephrologist name and contact information, patient history relating to kidney function, and indication of whether the biopsy is native or transplant. All vials must be labeled with the patient's full name and unique identifier. Avoid drying of specimens; make sure the specimens are completely submerged into the fixative and not caught on vial sides or in the threads of the cap.
Testing is ordered at the discretion of the ARUP pathologist; charges vary by individual patient.
