9. Before C-14 breath test, fasting is required, and strenuous exercise should be avoided after taking capsules. Pregnant women, pregnant women and lactating women should do this test carefully.

Food can directly affect postprandial blood sugar, so fasting blood sugar should be measured for at least 8 hours. If you draw blood at 7: 11 a.m. to test your fasting blood sugar, you can't eat any snacks, fruits and drinks before 11 p.m. the night before. But you can drink a little boiled water during this time. It is best to finish dinner before 8 o'clock in the evening and stop eating snacks after dinner. Blood sugar is unstable, so diabetics who use insulin before going to bed can add meals according to their usual habits.

The day before blood test, the diet should not change much. Don't eat and drink, especially don't drink, don't eat too greasy or too sweet and salty food, so as not to affect the test results.

It is not advisable to drink strong tea, coffee and other stimulating drinks before blood test for fasting blood sugar. If you feel thirsty, you can drink a small amount of boiled water, purified water, mineral water, etc., and the total amount should not exceed 111 ml.

vitamin c must be stopped 2-3 days before fasting blood glucose test, otherwise it will interfere with the real test results. Because vitamin C is a strong reducing agent, it can chemically react with reagents for testing blood sugar and urine sugar, so that the tested blood sugar and urine sugar content is low.
