Should trace elements be checked during a 1-year-old baby's physical examination

A 1-year-old baby's physical examination usually does not require routine testing for trace elements. Trace element detection is mainly used in clinical practice for children with specific nutritional deficiency symptoms or high-risk factors. If healthy infants and young children have no obvious abnormal symptoms, it is generally not recommended as a mandatory test item. The World Health Organization and pediatric guidelines from multiple countries indicate that healthy infants and young children fed a balanced diet have a lower probability of developing micronutrient deficiencies. Breast milk or formula milk, as well as gradually added complementary foods, are usually sufficient to meet the needs of a 1-year-old baby for trace elements such as iron, zinc, and copper. Routine physical examinations focus more on basic items such as growth curve monitoring, neurodevelopmental assessment, and blood routine screening for anemia, which can indirectly reflect nutritional status. Blindly conducting trace element testing may result in false positive results due to sampling errors and differences in detection methods, which can lead to unnecessary anxiety or excessive intervention. When a baby has symptoms related to trace element deficiency such as developmental delay, repeated infections, abnormal appetite, and changes in skin and mucous membranes, doctors will prescribe targeted tests based on specific clinical manifestations. High risk groups such as premature infants, low birth weight infants, and children with chronic diarrhea may also require monitoring of specific trace element levels. The test results need to be comprehensively judged based on clinical manifestations. If a single numerical abnormality is asymptomatic, it usually has no clinical significance.

Parents should pay attention to ensuring balanced nutrition through diet. The 1-year-old baby needs to take iron rich meat paste and iron fortified Rice noodles every day, together with vitamin C rich fruits and vegetables to promote absorption; Zinc can be supplemented through poultry and seafood; Dairy products and legumes can provide sufficient calcium. Regularly recording the trend of height and weight growth, observing the mental state and milestones of motor development, can more objectively reflect the health status of babies than trace element testing. If there are feeding difficulties or growth deviations from the standard curve, it is recommended to consult a pediatrician first rather than relying on laboratory tests.
