The University of Kansas Pathology Consultants, located in the heart of the Midwest, is committed to the highest quality of care and rapid turn around time for renal biopsy diagnoses. We provide a full range of diagnostic services for adults and children with kidney diseases in our CLIA certified laboratory. Our laboratory provides routine histology, immunofluorescence, immunohistochemistry and electron microscopy. Our pathologists call and fax preliminary results to referring physicians within 24-36 hours of receiving the specimen.

Biopsy Services and Results

Renal biopsies are processed the day of receipt for routine histology C1q, C3, IgA, IgG, IgM, C4d, Albumin, Kappa, Lambda and Fibrinogen. Special stains for light microscopy include PAS, Masson Trichrome and Jones Silver. C4d immunohistochemistry staining for human Polyoma virus (BK) in renal transplants is available. Electron microscopy is routinely performed to confirm and/or establish the diagnosis. To arrange a meeting to discuss our services, please contact Brian Donawa, Senior Administrator at 913.588.7070, email:

We offer rapid same day processing of the specimen, including review of material on weekends. The division is staffed by three renal pathologists with expertise in primary renal pathology and transplant renal biopsies and two technical staff. You receive with our services:

  • Physicians with extensive specialized experience in diagnosing renal pathology cases.
  • Nephropathologists who routinely collaborate on challenging cases for accurate diagnoses.
  • Rapid turnaround, of utmost importance to you and your patients.
  • Results called or faxed within 24-36 hours.

For Specimen Submissions, we provide:
