Do gynecological tumor indicators need fasting?

Gynecological oncology tests usually require fasting, which may vary depending on the hospital, test item and individual situation. Gynecological oncology tests usually require fasting. When performing gynecological oncology tests, the doctor will advise the patient not to eat or drink for at least 8 hours before the test to ensure the accuracy of the test results. This is because eating and drinking may affect the levels of certain tumor markers, resulting in inaccurate results. Specifically, the following are some reasons for fasting: 1. Diet Effects: Ingredients in certain foods and beverages may interfere with the detection of tumor markers, such as high-fat foods, high-protein foods, caffeine, etc. After eating, these substances may accumulate in the blood, affecting the concentration of tumor indicators and test results.2. Gastrointestinal activity: After eating, the gastrointestinal tract will undergo digestion and absorption processes, which may lead to changes in the concentration of certain components in the blood, thus affecting the detection of tumor indicators.3. Hormone levels: Dietary hormone intake may affect the levels of hormone-dependent tumor markers, such as estrogen, progesterone, etc. It should be noted that not all gynecological tumor markers require fasting examination, and specific requirements may vary according to hospital, examination items, and individual circumstances. Before the examination, the patient should consult the doctor or the examination institution in detail to understand the specific precautions and requirements. In addition, gynecological tumor indicators are only an auxiliary diagnostic tool and cannot be used as a basis for diagnosing cancer alone. If the examination results are abnormal, the doctor may recommend further imaging examination, pathological biopsy, etc. to confirm the diagnosis. For some special groups, such as diabetes patients, hypertension patients, etc., it may be necessary to adjust the diet and medication time under the guidance of the doctor to ensure the smooth progress of the examination. In short, in order to obtain accurate gynecological tumor index examination results, it is recommended that patients follow the doctor's advice before the examination and maintain an empty stomach. If there is any doubt about the examination, they should communicate with the doctor in time.
