What should patients be reminded of when taking blood? The best time to take blood should be in the

In general, the precautions for blood test mainly include the following points. The first is fasting and fasting, when doing blood tests, some laboratory tests need to be checked on an empty stomach, and it is not possible to eat at this time, which is the so-called fasting, generally speaking, fasting for six hours and drinking for more than four hours, such as blood sugar, liver function, etc.

The second is when to draw blood, because there is a part of this blood test, both need to be fasted at this time, you must follow fasting, and at the same time continue to check after meals, this part of the test mainly includes glucose tolerance test and insulin function These tests, at this time I must remember that the fasting test needs to be fasted, and at the same time, it also needs to be measured one hour after meals and two hours after meals.

Thirdly, there are some tests that can be checked at any time, such as blood routine, coagulation system, blood type, etc., so when doing the examination, we must ask the person who gave us the examination list and the precautions needed.

Summary. Hello Usually the blood collection of the physical examination should be carried out on an empty stomach before 8:00 in the morning of the second day of the physical examination, and the blood collection is most accurate during this time.

It is necessary to make an appointment at the hospital for a medical examination 1 day before the blood collection. After the appointment, the doctor will prescribe a laboratory test and instruct the patient to take precautions. After 8 p.m. the night before, try to avoid eating too many staple foods, especially foods that are high in protein, greasy, raw and cold, which are not easily absorbed and digested in the digestive tract.

Therefore, it is easy to have a clinical situation where the indicators are not accurate when the blood test is done the next morning. When you arrive at the hospital the next morning, you should avoid eating breakfast, because the blood test will affect the liver function and other things you eat, which will cause the index to be non-standard, and it should be completed before 8:00.

Because for blood routine, blood lipids, blood glucose, blood uric acid and other indicators, the measurement is most accurate relative to this time period. Because of the influence of endocrine factors, before 8 o'clock in the morning, it is the strong point of the body's glycemic index and positive stimulation hormone secretion, and blood sampling and testing are carried out at this time, which is relatively standard.

Because of the influence of endocrine factors, before 8 o'clock in the morning, in order to hide the body's glycemic index and positive motivation hormone to the vigorous point of secretion, blood sampling and testing at this time is relatively standard.

I'm still a little confused, can you be more detailed?

In general, it is best to check the blood routine in the morning on an empty stomach, and the results of the measurement are closest to the true value. Routine blood is a method of checking the number, shape and proportion of various blood cells in the human body by using a fully automatic blood analyzer, and the results are most accurate when fasting. The blood routine is easily affected by diet, especially after drinking a lot of water, because after a large amount of water is diluted, the concentration of various blood cells will decrease relatively, and the body's hemoglobin will also be relatively reduced, which may cause the patient to have the illusion of anemia.

In addition, if there is a significant change in the qi situation after a full meal or strenuous exercise, or when there is a significant change in the weather such as severe cold weather, high fever and other banquets, the number of white blood cells will increase significantly, and in the morning after sufficient rest, the body temperature is relatively low, and the measurement results are generally closest to the real level of the human body.

The training content of the phlebotomy collection personnel must include the following:

1. Laws, regulations and regulations, normative documents and standards of the Ministry of Health related to blood management.

2. World Health Organization (WHO) "Safe Blood and Blood Products" textbook.

3. All personnel participating in the assessment should read through the above content; According to the different positions, according to the following classification, read the corresponding part of the textbook of "Safe Blood and Blood Products".

Blood collection is a process in which medical personnel take blood samples through veins and arteries for testing or related needs. The preparation before blood collection is of great significance to improve work efficiency, ensure the safety of blood quality and blood donors, and the smooth progress of blood collection.

Blood collection shall be undertaken by medical staff and personnel trained in special blood collection techniques, and shall not be allowed to work without special training; The proficiency of blood collection technology is directly related to the quality of blood and the health of blood donors, so every blood collection personnel must be proficient in blood collection technology.

After donating blood, the cotton ball and adhesive tape covered with the eye of the needle should be kept for more than 4 hours to avoid infection of the eye of the needle. Check the puncture site for oozing or bleeding, and if there is bleeding, elevate the arm and continue to compress the area. After donating blood, you should rest in place for an appropriate period of time, and then slowly lift the blood donor up, and leave without abnormal reactions.

Attention should be paid to finding the cause of poor blood flow during blood collection:

1. The needle is not properly positioned in the vein, and the bevel of the needle is blocked by the vein wall or valve.

2. The puncture is too deep or the needle bevel does not fully enter the vein.

3. The blood collection catheter is squeezed, adhered or bent and deformed.

4. The pressure of the tourniquet is insufficient or too high, resulting in superficial vein filling or obstruction of deep venous return.

5. The blood donor is nervous and has a blood donation reaction, resulting in venous spasm or collapse.

Blood test is a routine test in clinical work, and attention should be paid to the following when performing blood test:1Before the blood draw, the specific items of the blood test should be clarified, and if there are items that need to be checked on an empty stomach, the blood should be fasted for 6-8 hours before the blood draw.

2.Avoid mental stress when drawing blood, and avoid adverse reactions such as blood sickness. 3.

After blood drawing, a sterile cotton swab should be used to press and puncture the needle hole for 3-5 minutes, and the cotton swab can be removed only after confirming that there is no more bleeding at the needle hole, so as to avoid local congestion caused by inaccurate pressing sites or too short pressing time. 4.Try not to take a shower on the day of the blood draw.

1) Strict aseptic operation technology, thorough disinfection, the range of Zhengsun poison is 8 10cm, after disinfection, the fingers are not chained to touch the puncture site, and the blood collector must often wipe his hands with ethanol cotton balls or towels soaked in peracetic acid solution during the blood collection process, and try to keep his fingers sterile.

2) Attention should be paid to finding the cause of poor blood flow during blood collection: the needle is improperly positioned in the vein, and the bevel of the needle is blocked by the vein wall or valve; The puncture is too deep or the needle bevel is not fully into the vein; The blood collection catheter is squeezed, adhered or bent and deformed; Insufficient or too high tourniquet pressure, resulting in superficial vein filling or obstruction of deep venous return; The blood donor was nervous, and Cong Heng had a blood donation reaction, causing the veins to spasm or collapse. Treat the above causes in time to maintain smooth blood flow.

3) Carefully check whether the number, name and blood type on the bag tag and tube tag are consistent, if the label falls off, the blood sample must be re-drawn from the blood bag to recheck the liver function and blood type, and the results can be sent out only after the results are consistent.

Answer: Pai Wei E

Induced abortion and logistics should be separated to avoid cross-feeling and dyeing, and the flow of staff and blood donors should also be separated as much as possible.
