Question
Doctor, hello! I want to check if my child is deficient in zinc or calcium, what kind of test should I do? Is it a trace element test? How much does it cost? Thank you!
Answer
The cost of trace elements should vary according to local prices. Trace element tests are generally conducted through blood tests from the fingertips, usually including calcium, iron, zinc, magnesium, iron, copper, and tin. If a child lacks a certain trace element, it is important to supplement it promptly to avoid affecting their growth and development. For example, a lack of calcium can lead to poor tooth development, night sweats, and restless sleep; a lack of zinc can cause poor appetite and picky eating; prolonged iron deficiency can lead to iron-deficiency anemia, causing dizziness and decreased immunity.
