Anonymous users2024-02-08Blood is a very important indicator in the physical health examination, and it is an indispensable part of the physical examination. Blood test is an important way to understand the health status of the body, dozens of biochemical data can be evaluated in the blood, and various physiological and pathological indicators are also an important reference for judging whether the body is healthy or not. But to get accurate results from a blood test, there are some things that must be taken care of:
Do not eat too greasy, high-protein food three days before blood drawing, avoid drinking a lot of alcohol (because the alcohol content in the blood will directly affect the results of the test), maintain a daily routine, fast for more than 8 hours the day before blood drawing, and it is best not to eat after 8 o'clock the night before, so as not to affect the detection of blood sugar and other indicators on the second day.
If you have a history of blood sickness, please let us know in advance so that you can make special arrangements.
On the day of blood drawing, it is required to take blood on an empty stomach before 9 o'clock in the morning, and if it is too late, it will distort the blood sugar value due to the influence of physiological endocrine hormones in the body, which will affect the blood drawing results.
Try to wear loose-fitting clothing when drawing blood and avoid meridians that compress your arms.
When drawing blood, you should be relaxed to avoid vasoconstriction caused by fear, which will increase the difficulty of blood collection, and also avoid syncope caused by neurovascular reflexes.
After the blood is drawn on the spot, press the pinhole site with a cotton swab or hemostatic tool for more than 3 minutes to compress and stop the bleeding. The clotting time varies depending on the individual's condition, and some people take longer.
Do not rub the pinhole to avoid causing a subcutaneous hematoma. If there is a small bruise at the place where the blood is drawn, and it is slightly tender, please do not panic, and you can apply a hot compress after 24 hours to promote the absorption of the bruises. A small amount of bruising will gradually absorb over 3 to 5 days and become lighter in color and return to normal.
If you have symptoms of fainting after blood drawing, such as dizziness, dizziness, fatigue, etc., you should immediately lie down, drink a small amount of sugar water, and then conduct a physical examination after the symptoms are relieved.

Anonymous users2024-02-061. Take a break before leaving.
Many people leave the hospital immediately after their blood is drawn, which is actually unsafe behavior. Although the dose required for a blood test is not very large, many people experience a little dizziness after the blood is drawn. In order to avoid accidents, it is recommended that you do not leave immediately after the blood is drawn, and sit in the hospital for ten minutes now, and then go home after the situation is really stable.
2. If you are dizzy, lie down for a while.
Dizziness after a blood draw is a common phenomenon because the person who has had a blood draw has not eaten in the morning and has low blood sugar. If this happens, it is best for the blood drawer to lie down for a while, eat something with higher sugar content, such as candy, sugar water, etc., or drink glucose directly.
If it is blood, you should not remove the hemostatic patch within four to eight hours after the blood is drawn, and you should not exercise moderately. >>>More
