The eleven liver tests are generally referred to as full liver tests. The cost of a full liver function test is usually between$80-150. Depending on the geographical location of the patient and the level of the hospital, the fee may fluctuate up or down. Patients who have their blood drawn for liver function tests are advised to have their blood drawn in the morning on an empty stomach, without drinking or eating. The liver function checked in this way is more accurate and can reflect the health status of the liver more comprehensively and correctly. Patients also need to fast for the physical examination because some patients may have to check the ultrasound of the upper abdomen. For upper abdominal ultrasound, if looking inside the gallbladder, it is also necessary for the patient to fast and perform without eating or drinking. Patients who drink or eat will cause the gallbladder to contract, which will further cause the gallbladder to become empty and then the ultrasound will not be able to observe the condition of the gallbladder. This makes it impossible to make a more correct diagnosis of the presence of stones and polyps in the gallbladder.
