Persistent immature grans/left shift on CBCs
My name is Lyda, and I've been trying to wrap my head around my recent CBCs that appear to have the presence of what they are calling a "left shift" / immature granulocytes. So CBC on Oct 2018 I had .10 / left shift. However CBC in Dec 2018 showed .05. Than Jan 2019 its back to .10 and March 2019 it is .11 My hematologist is "monitoring" these instances and I am slated for another CBC June 28, 2019.
I do have a couple of known diseases:
Thrombocythemia (CMS-HCC) [D47.3]
Hashimoto's disease [E06.3]
Mediastinal cyst (most likely benign from PET/CT scan done Feb 2019)
Both my PCP and my Blood Doctor aren't giving me too much information about these immature granulocytes and or why I am persistently having them. I did do a little research online and couldn't really find anything that stood out other than a severe infection. If anyone has any additional insight I'd love to hear it! Thank you.
