My 22 month old toddler has had very high vitamin b12 level (>2000) in two separate checks.
I was very concerned and read that high b12 is a symptom of cml.
Her recent CBC was also a little disturbing :
Wbc was 11.9 - elevated
Platelets were 337 bil/l - in the range ( 150-440) but slightly on higher side
Lymphocytes and monocytes are high but not others.
Her pediatrician has no explanation for the really high b12. I read that it is a symptom of CML - so. Am really concerned.
Though WBC is a. Little high - it could just be because of a cold or something. I am not sure whether to follow up or not. If this is really early stage - will the blood picture be almost normal ? Also I believe it's really rare in children this young. So I don't want to subject her to unnecessary tests.
Doctor says high b12 level is harmless - but I want to figure out why it is high?
She is a happy child otherwise - but has a low appetite.
