I took my son to the doctor because he needed a regular physical for school. I have had concerns about his weight since he was born. My son is 4 and only weighs 36 pound. He had an absolute eosinophil count of 858 and a calcium of 10.6.these were the only two outliers in his blood test results.I am very concerned about the eosinophils count.
Hi, I am Chat Doctor.  Absolute eosinophils count of 858 /UL indicates mild eosinophilic, most common cause for which is allergy and or worm infestation. If otherwise normal he needs deforming if not done already. If everything is normal on physical examination, I do not think it is a cause of concern. Serum calcium is slightly on higher side, if serum PTH level is normal, it is not cause of concern if physical examination is normal. Other common cause at this age is more use of vitamin D , he may need evaluation for this. If your child has no other symptoms/signs , I think it is not related to something serious.
