Sometimes when going to the hospital for blood tests, doctors will remind people not to eat in the morning. Sometimes blood tests can be taken without the doctor's reminder, even after eating. Does it mean that some tests require fasting while others do not? Can a 3-year-old baby draw blood after eating?
If the baby's blood is drawn for liver function test, food should not be eaten before the test so as not to affect the accuracy of the test results. However, other blood drawing test items, such as renal function, electrolyte, myocardial enzyme, troponin, blood routine test, hepatitis B B penta and procalcitonin, are not affected by food. Food can be eaten before blood drawing for these tests.
During blood tests, some items cannot be eaten before the blood is drawn, but not all items require fasting. Fasting blood tests are mainly required for liver and kidney function, blood lipids, and blood sugar. If there are significant fluctuations in the results of these items after eating, it will affect the doctor's diagnosis.
For a three-year-old baby, it is important to develop good lifestyle habits and focus on a light and easily digestible diet, avoiding overeating. After the baby has drawn blood, it is important to supplement nutrition and maintain a relaxed mood.
