What items do blood tests generally check in physical examination?

? Blood routine is a very important and necessary item in physical examination. In order to ensure the accuracy of the test results, we should pay attention to some problems before blood test. In addition, because blood test is the first step of physical examination, maintaining a stable mentality is conducive to the accuracy of the test results.

On the day before physical examination and blood test, it is best not to eat high-protein and greasy food or drink alcohol, because these foods and alcohol will directly affect the proportion of blood components, and then affect the test results. Ask a doctor for different laboratory tests and treat them differently. Before the blood lipid test, it is best not to eat foods with high fat, such as sparerib soup and steamed meat. At the same time, don't wear clothes whose cuffs are too small and too tight on the day of blood drawing, so as not to roll up the sleeves during blood drawing or too tight after blood drawing, resulting in arm vascular hematoma.

Generally speaking, blood tests should be carried out on an empty stomach, such as liver function, sugar, protein, lipids, various inorganic ions (potassium, sodium, calcium, phosphorus, etc. ). If you have special needs, you can also take blood 6 hours after a light diet according to the doctor's advice, but when you do a blood lipid physical examination, you must take blood after meals 12 hours. People's blood sugar will rise after eating, and it will gradually return to normal in about 2 hours, so it is necessary to do blood sugar test on an empty stomach. The same is true for blood lipid analysis. Because chylomicroemia may occur after eating, which seriously affects the determination results, fasting 12 hours or more is required to draw blood.

There are three major problems in the requirements of physical examination and blood test. It is forbidden to be greasy the day before blood drawing, and wear loose clothes on an empty stomach in the morning on the day of blood drawing. At the same time, after the blood test, there are some other matters that need everyone's attention, so as to ensure the quality of blood and the accuracy of this physical examination.
