Interpretation of Results
- The patient exhibits normal absolute expression of all adhesion molecules
tested. However, when the antigen density (mean peak channel fluorescence-
MPC) is examined, the patient unstimulated appears to express over four
times the antigen density as the healthy control. The granulocytes appear
to be up regulated
in vivo to a degree thereby limiting the final
stimulation index value (see histograms below). However, the stimulation
index is just within the normal range (SI=3-30).
