CD23 Positivity Robin.Allen at

Can anybody offer any advice on lymphocyte subset results we have
recently obtained on a 42 year old woman, presenting with a mild but
persistent lymphocytosis.

Her Total WBC is 12.2 x10E9/L
Lymphocyte Count: 6.3x10E9/L 

Marker results:
CD2     91%      
CD3     82%         
CD4     21%
CD5     86%
CD8     47%
CD10     4%
CD19   10%
CD20   10%
CD23    83%
CD56   14%
FMC7    3%
SmIg    16%

Given the T-cell proliferation, I am unable to explain the CD23 positivity
which is showing very strong fluorescence. The test has been repeated
with similar findings.

Any suggestions would be gratefully received.
