Clinical Partnership with MCW
Our concierge-level renal pathology service centers on individualized consultation for every case. We provide accurate, actionable diagnoses within 24 hours of specimen receipt and immediately communicate preliminary results directly to the treating physician.
We emphasize continuous clinicopathologic correlation, keeping lines of communication open so nephrologists and clinical teams have fast, clear diagnostic clarity when managing complex patient care.
Treating physicians have direct access to our renal pathologists via phone, text, email, or video conference for follow-up discussions and preliminary case reviews.
We also support multidisciplinary care by scheduling in-person or virtual kidney biopsy conferences tailored to your clinical group's needs.
Comprehensive histological analysis on native and transplant kidney tissues using serial sectioning and specialized histochemical staining protocols.
Rapid panel processing for immunoglobulins (IgG, IgA, IgM), complement components (C3, C1q), and kappa/lambda light chains to evaluate immune-mediated disease.
High-resolution transmission electron microscopy (TEM) in-house for evaluating ultrastructural basement membrane changes, podocyte effacement, and immune deposit localization.
PLA2R tissue staining for membranous nephropathy, and IgG subclass analysis (IgG1, IgG2, IgG3, IgG4).
Congo Red staining with polarized light examination for amyloidosis detection, along with Paraffin Immunofluorescence when frozen tissue is insufficient.
C4d immunohistochemistry / immunofluorescence, viral IHC (SV40/BK virus, CMV), and comprehensive antibody panel evaluations.
WDL and MCW Renal Pathology provide consultative review services for diagnostically challenging or complex kidney biopsy cases, including glomerular diseases, transplant rejection, tubulointerstitial disorders, and rare vascular lesions. Consultative cases may be submitted for subspecialty review and clinicopathologic correlation through our pathology consultation program.
