Risk Stratification in Chronic Lymphocytic Leukemia
The Role of the Clinical Laboratory
ZAP-70 by Flow in CLL

November 2008
Here’s another example. Again, in the upper left histogram, quad stats are set based on 0.10% ZAP-70 positive B-cells. In the upper right histogram, one sees that the T-cells and NK-cells are appropriately positive.
In the lower left histogram, we see the patient of interest and indeed, in contrast to the previous patient, we see here if we take 62.5% divided by the total B-cell percentage, that we end up with 76% of the B-cells expressing ZAP-70, which would be interpreted as positive for this particular patient.
