Taboos in blood drawing physical examination

Editor's note: Blood sampling is a common physical examination item that everyone will do, but do you know some taboos in blood sampling? Taboos of physical examination: blood collection is also taboo, such as taking blood on an empty stomach, not wearing clothes with tight cuffs on the day of physical examination and so on!

First of all, when you see a doctor, you must cooperate with the doctor to write down your name correctly and neatly. Avoid the confusion of the same or similar names, which will bring you inconvenience.

Second, when doing biochemical examination, blood must be drawn on an empty stomach. Generally speaking, the so-called tests that need fasting blood are mostly biochemical tests. Such as liver function, sugar, protein, lipids and various inorganic ions (potassium, sodium, calcium, phosphorus, etc. ).

If you have special needs, you can also take blood samples 6 hours after a light diet according to your doctor's advice; However, when doing blood lipid examination, blood must be taken after meals 12 hours.

3. Fasting blood refers to venous blood collected about 12 to 14 hours before eating in the morning. Since the digestion and absorption activities of gastrointestinal tract have been basically completed 12 ~ 14 hours after meals, various biochemical components in blood are relatively constant. At this time, the measured values can truly reflect the biochemical changes of the body and contribute to the diagnosis of diseases.

Fourth, don't wear clothes with too small and too tight cuffs on the day of blood drawing, so as not to roll up the sleeves during blood drawing or the sleeves are too tight after blood drawing, resulting in arm vascular hematoma.

Five, according to the different examination items, ask the doctor to treat them differently. For example, blood sugar test, postprandial blood sugar, must be checked after eating; Blood sugar before meals, you must check it when you don't eat in the morning; It is best not to eat foods with high fat content, such as sparerib soup and steamed meat, before blood lipid examination.
