The following tests are required before gastroscopy, including infection marker test, electrocardiogram, blood pressure test and coagulation function test.
1. Infection marker examination: Before performing gastroscopy, the examination of infection markers such as Hepatitis B, Hepatitis C, Syphilis, AIDS and so on should be completed in order to avoid cross-infection during the examination. After the examination, if the test result is positive, it is necessary to carry out strict sterilization and protective measures during the examination.
2. Electrocardiogram: Electrocardiogram is mainly to rule out the presence of arrhythmia, myocardial ischemia, myocardial infarction and other heart diseases. This test prevents patients from having accidents during gastroscopy.
3. Blood pressure check: Before performing gastroscopy, it is important to know whether the body’s blood pressure is within the normal range. If the blood pressure is abnormal, it is necessary to take antihypertensive medication under the guidance of the doctor and in conjunction with one’s own physical condition. Wait until the body’s blood pressure has recovered to the point where it can tolerate the procedure, and then the gastroscopy can be performed after the doctor’s evaluation.
4. Coagulation function test: Before gastroscopy, a coagulation function test is required, and patients need to stop taking anticoagulants to avoid affecting the accuracy of the test results.
In addition, patients may also need to undergo blood tests, liver and kidney functions, abdominal CT and other tests before gastroscopy, so be sure to follow the doctor’s advice to carry out the relevant preparations, so as not to affect the gastroscopy.
