Fasting before the blood test is necessary for some tests. This is because during these tests, your doctor will ask you not to eat or drink anything for a few hours before the test.

Fasting before the blood test is an important issue. This action helps you to be sure of the accuracy of the test results.... Vitamins, fats, carbohydrates and proteins in food and drinks definitely affect the parameters obtained from the blood test.... These substances put the results obtained from the test in an aura of ambiguity..

All Blood tests do not require fasting before the test..

  • Blood sugar test
  • Liver function test
  • Cholesterol test Triglyceride test
  • High-density lipoprotein (HDL) test
  • Low-density lipoprotein (LDL) test
  • Basic metabolic panel
  • Renal function panel
  • Lipoprotein panel

If the doctor has prescribed a new blood sugar test for you, but has not determined the necessity of fasting and its duration, ask him about the necessity of doing this method.

Red meat, broccoli, and even some medications can lead to a false-positive test result...so it's best to always follow your doctor's advice when preparing for a test.

1... How many hours should we fast before the blood test?

The length of time you fast before a blood test varies depending on the type of test....most tests require you to have nothing but water for 8 hours before the test....a limited number of tests require a 12-hour fasting period.

2.... Is it permissible to eat coffee while fasting before the blood test?

?.

Drinking empty coffee (black coffee) before taking a blood test may interfere with the results. This is because coffee contains caffeine and soluble plant substances. These substances can potentially lead to the deviation of blood test results.

Furthermore, coffee is a diuretic....that is, its consumption leads to more urine....in fact, coffee has a dehydrating effect.

Drinking water increases the volume of water in the body...so the veins dilate and become more visible...drink plenty of water two days before the test...also try to drink a few glasses of water before donating blood...this will make it easier for the nurse or medical professional to find the vein.

4.... Should children also be fasting before the blood test?

Children, like adults, are subjected to a series of tests that require fasting... If necessary, the pediatrician will give you instructions not to consume food or water.

  • Plan your child's blood test so that it is done at the beginning of the day as much as possible.
  • During the fasting period, regularly distract them. The hours before the exam are considered the best time to give them the opportunity to watch cartoons on TV or play with the iPad.
  • Buy a snack for your child to eat as soon as the test is over.
  • If your child managed to eat something before the test due to your carelessness, it is better to change the time of the test because otherwise the results will be incorrect.

5.... Should we fast before blood test during pregnancy?

If you are pregnant, you will probably need several blood tests... The purpose of these tests is to address any potential health threats to the mother or fetus, during pregnancy or after birth... Some of these tests also require you to fast before the test.. Stay away from water or at home.... These recommendations are suggested to increase the general well-being of the person being tested.... These recommendations apply especially in very hot and humid weather. be.
