Which physical examinations require fasting?

I believe that in daily life, every friend will be asked to take a physical examination after applying for a driving school. And many friends will also be asked by the company to take a physical examination after the interview. From this we can see that physical examination has become an indispensable thing in people's lives. So which physical examinations require fasting? In order to better help everyone solve this question, please join me in today's learning content.

Color Doppler Ultrasound (Gastrointestinal tract, Gallbladder)

Examination of the gastrointestinal tract The gastrointestinal tract often contains a large amount of gas. When people eat, a large amount of gas can be sent into the gastrointestinal tract as they swallow food. These gases will interfere with the passage of ultrasound, affect the clarity of the image, and easily cause misdiagnosis or missed diagnosis.

The physiological function of the gallbladder is to store bile. Under normal circumstances, the gallbladder will contract and discharge bile after a person eats fatty foods. When the bile in the gallbladder decreases, it is not easy to see the lesions on the gallbladder wall during B-ultrasound examination.

C14 (Helicobacter pylori test)

Because if there is chyme in the stomach, the urea capsule and Helicobacter pylori cannot fully contact each other, which will affect the test results.

Since fasting for a long time is not good for the body, it is generally recommended to coordinate meal times, try to cooperate with physical examinations, and eat in time.

Some routine physical examinations still require fasting. You don't have to fast for a routine urine test, but you do need to fast for a routine blood test or liver function test. A routine blood test is something that everyone who has a physical examination will do, but for some reasons, many people will only do some routine blood tests. The routine blood test checks parameters such as red blood cells, white blood cells and platelets, so fasting is required. Urinalysis tests are to check for blood cells, urine bilirubin, urine specific gravity, etc., so fasting is not necessary. If you are checking liver function, some bile enzymes are affected by eating, so fasting is required. If it is an outpatient condition, you can wait for the results in the outpatient clinic 1-2 hours after blood draw.

I believe that through the above learning, most of our friends have a deeper understanding and more proficient grasp of which physical examinations require fasting. Of course, I want to tell you that physical examinations are not only for us to know our physical condition clearly, but also to avoid some diseases from being transmitted to others when we come into contact with others. So we must pay more attention to the issue of physical examinations.
