Knowledge Point

Which tests require fasting and which require holding in urine?

Organ examinations require fasting: liver, gallbladder, pancreas, spleen, renal blood vessels, abdominal aorta, etc. Because on the one hand, food will cause the gallbladder to contract and empty bile, the structure and shape of the gallbladder will be affected by ultrasound after the gallbladder contracts. On the other hand, the abdominal contents and gastric gas after eating will be affected, and some ultrasound sections will not show clearly. It is easy to misdiagnose or miss the diagnosis and delay the condition.

Is ultrasound harmful to the body?

The medium used in ultrasonic examination is ultrasonic wave, which has no ionizing radiation. The conduction in the human body uses the characteristics of sound waves, just like the sound of our speech. Ultrasound examination is a very safe examination and is therefore commonly used in obstetrics to examine the fetus.
