Question
Does a 15-month-old baby need to fast before a trace element test? Will it have any effect if they had a feeding in the middle of the night?
Answer
The measurement of trace elements usually does not require fasting. Only a small amount of fingerstick blood is needed for the test. If the doctor recommends fasting, it may be related to the testing method they are using. It is advisable to consult with the doctor about the reason for fasting. Additionally, requiring the baby to fast for 12 hours may make them uncomfortable.
