Persistant high platelets, doctor can't figure it out
I want to preface this with saying I am currently seeing a hematologist, so I'm just more curious if anyone has ideas, rather than this being a substitute for going to the doctor.
I started having consistently high platelets (between 5-600 k/ul) several years ago. My PCP finally sent me to a hematologist about a year ago, who assured me they would "figure it out". Which they obviously haven't, so now I'm just going on every 3 months for tests to see if they go back down on their own. They have run many tests, including a bone marrow biopsy, and found nothing. Anyone have any thoughts?
I've had scattered but not crazy out of range abnormal results (like, 1 or 2 tests out of 4) for the following: c- reactive protein, manual and auto neutrophil, monocytes, sedimentation rate, auto immature granulocyte, MCHC, and reticulocyte. Some but not all of the tests have found abnormal platelet morphology and giant platelets.
My iron has consistently been weird (see pics).
I have high cholesterol and am in perimenopause. The only medication I'm taking that I think would affect my results is oral birth control? Happy to share any other test results.
