Patient's question:
Trace elements checked, lead 34 reference value 1.0-100.0, copper 21.3 reference value 11.8-39.3, zinc 90.6 reference value 58-100, calcium 1.95 reference value 1.55-2.10, magnesium 1.82 reference value 1.12-2.06, iron 8.44 reference value 7.52-11.82.Doctor's answer:
There are many reasons for a large head circumference, such as being larger than peers at birth, intergenerational inheritance, hydrocephalus, etc. For the above trace element tests, all were normal, and the main reason for the large head circumference is primarily ruled out as hydrocephalus. If the child's motor development and language development are normal, then the large head circumference does not need to be addressed. The above is advice on the question "Is the large head circumference due to trace elements?" I hope it helps you. Wishing you good health!
