Can I eat breakfast while doing a blood test?

A routine blood test is the most basic physical examination. Before doing it, you must understand some precautions. For example, you need to fast before the test. This is because diet may affect the diagnostic results of the routine blood test. It should also be noted that the diet should be as light as possible in the few days before the test. After the test, stop the bleeding in time to avoid subcutaneous hematoma.

Can I eat breakfast when I have a blood test?

You cannot eat breakfast. You need to be on an empty stomach, otherwise there will be some effects. The fasting time needs to be advanced to 8 pm the night before. Try to avoid eating after that. Also, don't eat too much meat in the days before the test. Eat mainly vegetarian food, so that the test results are relatively accurate.

Precautions

1. Before the inspection

(1) Do not eat greasy or high-protein foods or drink large amounts of alcohol the day before blood collection. The alcohol content in the blood will directly affect the test results.

(2) You should fast for 12 hours starting at 8:00 pm the day before the physical examination to avoid affecting the test results.

After 8 pm the day before the physical examination, you should start fasting for 12 hours.

(3) When drawing blood, you should relax to avoid blood vessel constriction due to fear, which will increase the difficulty of blood collection.

2. After the inspection

(1) After drawing blood, apply local pressure on the needle hole for 3-5 minutes to stop the bleeding. Note: Do not rub to avoid causing subcutaneous hematoma.

(2) The pressing time should be sufficient. The clotting time varies from person to person, and some people need a little longer to clot. Therefore, if you stop applying pressure immediately when the surface of the skin seems to be not bleeding, the bleeding may not stop completely, and the blood may seep into the subcutaneous layer, causing bruises. Therefore, pressing for a longer time can completely stop the bleeding. If there is a tendency of bleeding, the pressing time should be prolonged.

(3) If you experience symptoms of needle phobia such as dizziness, blurred vision, fatigue, etc. after blood draw, you should lie down immediately and drink a small amount of sugar water. Wait until the symptoms are relieved before undergoing a physical examination.

(4) If local bruising occurs, apply a warm towel for 24 hours to promote absorption.
