Does the baby need to fast when checking liver function?

As we all know, during the growth stage of babies, the organs in their bodies are not particularly mature and are very fragile. Therefore, the function of organs is very important for babies. Most liver diseases have certain genetic factors. At this time, we must pay attention to checking the liver function of babies to prevent them in advance. So, do you need to fast when checking the liver function of your baby?

Do babies need to fast for liver function tests?

Babies need to fast before having their liver function tested. For children with jaundice, it is necessary to conduct a liver function test to determine the specific value of bilirubin. It is also necessary to check whether there is any liver damage to clarify the cause of the child's jaundice. You need to fast before doing a liver function test. The fasting time should be at least 4 to 6 hours. If the fasting time is too short, it will seriously affect the test results.

Reasons for fasting before liver function tests

Liver function is a routine examination item. All liver function tests require fasting blood draw. This is because normal human blood contains a certain amount of large molecular β and γ globulins, which can combine with certain chemical reagents to precipitate, while small molecular albumin and α1-globulin can prevent the formation of precipitation.

That is to say, after eating before the liver function test, the composition of the serum will definitely change. After adding chemical reagents to the blood drawn during the test, even the serum of a normal person will precipitate to varying degrees, especially after eating high-protein or high-fat foods. Obvious precipitation is more likely to occur. At this time, the test results can easily cause doctors to misdiagnose normal people as hepatitis patients.

Therefore, it can be seen from the above that fasting is very necessary before testing liver function. Even babies are the same. Therefore, parents should not be reluctant to let their babies fast, but they should know whether to feed their babies during the check-up. It is likely to lead to serious deviations in test results, thus causing misdiagnosis and leading to more serious adverse consequences.
