Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.
The first 9 stains are not orderable individually but are performed when 8104 Renal Biopsy, Immunohistology is ordered. In most cases, the first 9 immunofluorescent stains are the only ones required and performed. In certain cases pronase-digested paraffin-based slides can be used for immunofluorescence staining as a salvage technique when there is no Zeus sample or an inadequate Zeus sample (eg, no glomeruli). Determining the subtype of IgG antibody found in renal immunofluorescent panel can be helpful in confirming a select few disease processes affecting the kidney. The C4d stain will be setup on Zeus specimens for transplant/allograft kidney biopsies. The C4d stain can also be ordered separately without the full immunofluorescence panel stains.
88501 Renal Pathology Consultation and 8331 Renal Biopsy, Light Microscopy must be ordered with this test and will be charged separately.
