Question
How can a baby’s liver and kidney function be checked?
Answer
When conducting a kidney function test, it is necessary to fast and avoid drinking water, as eating can affect blood sugar levels. Additionally, after a meal (especially a heavy one), an increase in gastrointestinal contents may compress organs including the kidneys, leading to unclear organ edges, missing information, and potentially confusing the test results. Therefore, it is usually recommended to perform kidney function tests on an empty stomach in the morning.
