I believe everyone knows that it is best to have regular physical examinations every year, which can detect the existence of diseases in advance and provide timely treatment. But in reality, many people do not know the significance and items of physical examination, and always wait until the last step to get checked. So, is biochemical routine examination a blood draw?

There are many biochemical examination items, which belong to blood sampling examination. Different projects have different requirements for preparation before blood draw. Biochemical tests for liver function, blood glucose, and blood lipids require fasting for at least 12 hours, followed by centrifugation and extraction of 2-3ml of venous blood for testing. Kidney function tests and trace element tests generally require fasting for at least four hours. Blood routine examination can be performed simultaneously with biochemical examination, and blood can be drawn from fingertips or earlobes at any time.
Biochemical screening routine examination is used for routine physical examination and screening and confirmation test of diseases. It is a comprehensive examination of the body and a way to understand the physical condition. Sometimes it can also detect latent diseases. For example, hepatitis B virus carriers need to go to the hospital every other time for examination, such as liver function examination, to prevent the sudden onset of disease and timely treatment.
There are many people in life who are afraid of pain, and some people suffer from dizziness. These people are particularly nervous when drawing blood, and if they are too nervous, it can cause blood vessels to contract, making it difficult to draw blood. Blood vessels will contract severely and become very small under tension. Getting a needle is very difficult, so it is important to relax during a physical examination and blood draw.
