I'm happy that you have asked me to assist you with your child and hope that you can benefit from my many years of helping parents like you.
Hi. Can you tell me what his white count and absolute neutrophil counts are?
I'm seeing patients but will watch for your reply.
His WBC and ANC while low are not dangerously so but obviously he has something going on with his immune system, especially with the IgM.
Is he going to see an immunologist?
I doubt cancer or leukemia with a normal red cell count and platelets, which I assume was the case.
More likely is that he has one of the immune disorders, many of which can be transient, and the immunologist and/or hematologist can sort this out pretty quickly with some blood tests.
His ANC (absolute neutrophil count) is high enough that he should not be at much risk for infection right now but certainly the underlying cause needs to be determined.
Transient meaning temporary, and these are usually due to some infection or toxin, such as a drug reaction.
Be sure to check with your relatives about any immune disorders in the family history as well as all medications he's been on in the past 6 months.
