Before the carcinoembryonic antigen (CEA) test, here are some things to pay attention to:
1. Diet:
Generally speaking, there is no need to strictly fast before the test, but it is recommended to maintain a light diet and avoid eating a lot of greasy, high-protein or overly irritating foods.
Medication:
Some drugs may affect the test results of CEA. If you are receiving medication, especially high-dose biotin treatment, you should inform your doctor in advance. You may need to collect samples 8 hours after the last biotin treatment.
2. Lifestyle:
Avoid excessive fatigue and strenuous exercise before the test, and get enough sleep.
Try to reduce smoking and drinking as much as possible, as smoking may increase CEA levels.
3. Others:
Inform your doctor of your health status, including whether you have chronic diseases, recent infections or inflammation, etc.
If you have done relevant tumor marker tests or other cancer-related tests before, you should bring the test reports for your doctor's reference.
It should be noted that there may be some subtle differences between different medical institutions and test methods. Before taking the test, it is best to consult a specific testing agency or doctor to obtain the most accurate and detailed precautions.
