welcome to HCM.
High ALP, High platelets may point to increase marrow activity but not necessarily . Before thinking about rare causes it is better to rule out common causes like anemia
.A coulter count of cbc may not always reflect the blood picture as much as a peripheral smear, which can show morphology and abnormalities of rbc
and platelets.So before coming to any conclusion repeat a peripheral smear and serum calcium and later if suggestive vitamin b 12 and iron studies. Hope I could help you.
