Trace elements play a vital role in children’s growth, with zinc being an important component that supports the activity of over 200 enzymes. It has a profound impact on the metabolism of nucleic acids, proteins, sugars, and bone calcium, promoting growth and tissue repair. Both zinc deficiency and excess can be detrimental to health, especially during periods of excessive sweating, diarrhea, or rapid growth, making it crucial to maintain an appropriate level.
Iron is critical for children’s blood production and oxygen transport, particularly between the ages of 6 months and 2 years. Iron deficiency may lead to symptoms such as pallor, fatigue, and loss of appetite, and can even affect cognitive function. Iron levels should be maintained in the middle of the normal range to prevent potential health issues.
Copper, while less frequently deficient, is also important for blood production and bone development. A varied diet rich in orange, red, and yellow fruits and vegetables can effectively prevent copper deficiency. Excessive copper levels may interfere with the absorption of calcium, iron, and zinc, so maintaining balance is key.
Calcium is a major component in building bones. Although calcium in the blood accounts for only 1% of the total amount, its balanced state is significantly important for overall health. When assessing children’s calcium nutritional status, in addition to blood tests, clinical manifestations and comprehensive testing such as bone density should also be considered.
Lead, as a toxic heavy metal, has serious effects on the nervous system and multiple bodily systems, particularly affecting infants who are more sensitive. It may cause behavioral abnormalities and developmental delays. Low iron levels can exacerbate lead absorption, thus monitoring and controlling the lead levels in children is essential, with an ideal level being below 50ug/L to ensure they are not at risk of lead exposure.
When parents receive their child’s trace element test report, they should focus on two main aspects: first, the specific levels of trace elements, and second, the normal reference ranges for these elements. Any deviation from the normal range should be taken seriously, and timely measures should be taken to adjust and ensure the child’s healthy growth.
