My WBC goes up and down as well. This is due to the fluctuation of my absolute lymphocytes. When they spike the rest of my white blood cells go down. I was 16.3 on my ab lymph and my neutrophils were at 0.7. my WBC was 19.6. 2 weeks later my ab lymph was 12.2 and my neutrophils were at 4.4 and WBC at 16.2. It's a rollercoaster ride.

yes. My doc recently said not to worry about WBC. Whatever that means. More important is neutrophils as Bob mentioned. And if you are starting a new drug, remember that it is to activate your system so the general rule is your counts will go up before they come down. I was on Calquence for a month and my WBC went from 158 to 6. Looks shocking but I guess that's the magic.

Yes, mine fluctuate up and down as well.

My WBC fluctuates also.

Hi Marilyn!
I have CLL and my white cells are doing the same thing as yours…
I’m meeting with my oncologist tomorrow to find out why…
I do blood work once a week and last week it was 3.2 and this week it’s 2.4 Very frustrating
If I learn anything tomorrow from my doctors appointment I’ll share it with you. Hugs
