Yes I have the 13 deletion too I think the one to be careful about is the 17 deletion.

My del13q14 result was determined at diagnosis. Three years later I elected to start treatment with Calquence. I had rough 3 month start(infections) but now am doing fine with WBC in the normal range.

There are several markers (gen deletions) for CLL. Some have a better prognosis than others. When I was tested, I found I have one abnormality, q 13 del. This one happens to have a favorable prognosis. I'm a lucky kid!

Yes I had this done the same time I had my flow cytometry test. I knew my deletions when I went into my first visit with hema/onc.

Hi Heleen.
I have CLL/SLL. When I went to the hospital on January 26,2018 my hemoglobin was 48. I was getting blood every other day until I saw my hematologist in March.
I was diagnosed March 29th with stage 3 CLL/SLL.
We discussed treatment options including chemotherapy. Before we started my treatment, she put me on a very high dose of prednisone and sent my blood for the test you mentioned.
The test took 7 weeks to complete.
When she received the results, she decided that the best treatment for me was 420 mg. of Imbruvica daily.
I have been in treatment 67 months now and living a fairly normal life at 75yrs old.😊
