Re: High platelet & white cell counts
First of all, find a good hematologist. Your condition is unlikely to escape a good specialist.
I have high platelets, but my white count is normal. Thus our conditions are not completely the same. I am diagnosed with Essential Thrombothycemia (ET). All it really means is that I have high platelets and that there is no apparent underlying cause. Fortunately, my platelet count has remained stable. Many patients with ET live full lives and exhibit no other symptoms. So far so good for me.
Back to hematology. My DR did some genetic testing to check for mutations which can affect blood disorders. I'd bet that you could find a hematologist who could run additional tests for you to help determine why your counts are high.
