What are the precautions for routine blood tests

A routine blood test is a very common and very effective examination method. This is mainly because our body's blood circulates throughout the body's organs and penetrates into various tissues. It also participates in the body's metabolism and plays a key role in the balance of the body's internal environment. It also carries a variety of physiological and pathological information. Therefore, a routine blood test can clearly diagnose some diseases, but there are many things to pay attention to in this examination.

Precautions for routine blood tests can be divided into two aspects: before and after the examination. Precautions before a routine blood test: Within one week before the test, you should avoid overeating, drinking large amounts of alcohol, and eating spicy and irritating foods to prevent temporary changes in blood components due to food stimulation, which may affect the results of the physical examination. Three days before the examination, you should avoid heavy physical labor, strenuous exercise and highly intense mental work, keep your mood relaxed and get enough rest. Starting from 8 pm the day before the examination, do not eat or drink anything, and do not have breakfast until the next morning. Go directly to the physical examination center for the examination. After the examination, you can enjoy a nutritious breakfast for free, and then concentrate on the remaining examination items.

It is best to take a shower before the physical examination and clean the area where blood will be drawn to prevent infection. When doing a routine blood test, you should relax. It is not as painful as the legend says because it does not puncture the flesh. Therefore, you will only feel a slight pain during the puncture and then the pain will go away. Female friends, please do not be overly nervous. Precautions after routine blood test: After blood drawing, press the blood drawing site with three fingers for ten minutes to avoid bleeding. If the pressure is not applied for a long enough time or the pressure is applied incorrectly, it may cause bruising at the blood drawing site, which may be large or small. If this symptom occurs, don't panic. Generally, the bruise will disappear naturally. Applying a hot towel 24 hours after the blood is drawn can also speed up the disappearance of the bruise.

Routine blood tests can not only diagnose diseases, but also for some patients after treatment or during the treatment process, doctors also need to conduct routine blood tests in order to clearly understand whether the drugs are effective or to understand the patient's recovery status. In order to improve the accuracy of routine blood tests, the above precautions must be taken seriously.
