Just wondering if anyone can shed a little light on how I should read some flow cytometry results, please?
I am in the UK (I guess different indicators/symbols may be used in other countries...) but I would like to know what the "+" symbol means when it follows a CD number, e.g. CD19+, CD23++, etc?
How many "+" symbols indicate dim, moderate and bright expression? I mean, is CD23++, for example, moderately or brightly expressed?
Also, I note some of the CD numbers on the flow cytometry report are followed by a "+" symbol over a "-" symbol (sorry but I can't reproduce the symbol here....it's either the limitations of my phone or simply me being a bit thick!).
Anyway...if anyone can explain the significance of these symbols I'd be most grateful.
Having CLL is proving to be one huge learning curve!☺
Thanks very much!
