Clinical Interpretation

Reference Range:

No reference range established in this institute. In general the tissues that contain sarcoid granulomas exhibit a CD4:CD8 ratio of 10:1 or greater compared with a ratio 2:1 in uninvolved tissues


Test Comments:

CD4:CD8 Ratio will be automatically ordered and charged when %Lymphocyte on differential are > 15% on the fluid cell count order


Methodology:
  • Flow Cytometry (FC)
