Do I need to test transaminase on an empty stomach?

Generally speaking, fasting tests can improve the accuracy of test values, especially when testing blood sugar, you must fast, because the blood sugar level when fasting can best represent the patient's blood sugar status at normal times. Through the detection of alanine aminotransferase, it is possible to effectively infer whether there is a problem with the patient's liver. Many people wonder whether they need to fast before testing alanine aminotransferase.

Can I eat before testing my transaminase?

The transaminase test requires a fasting blood test, which means do not eat before the blood test. The fasting time is generally 8-12 hours.

Can I take medicine before testing transaminase?

If you can't eat, can you take medicine? If you have other diseases, you can take medicine a few days before the examination, but you cannot take medicine on the day of the examination.

Can I drink water before testing my transaminase?

Many people, especially those who are undergoing pre-employment physical examinations, are worried that elevated transaminase levels will affect their employment, so they deliberately drink plenty of water before the physical examination in an attempt to lower their transaminase levels. Is this useful? No, it may even have the opposite effect!

If you are really thirsty before the physical examination, it is okay to drink a few sips of water, but if you deliberately drink a lot of water, it is likely to cause an increase in transaminase, because drinking a lot of water may increase the burden on the liver and heart, leading to an increase in transaminase.

Don’t do these things before testing your transaminase:

1. Don’t eat too greasy food. You should eat light food one week or at least three days before the examination, and avoid fried, grilled, fatty, or greasy foods. Bad eating habits may affect the transaminase values.

2. Don’t stay up late. We all know that staying up late is very harmful to the liver. One week before testing the transaminase, it is best to go to bed at 10:30 p.m., and going to bed after 11 p.m. will be considered staying up late. If you don't want your transaminase to be high during the physical examination, you must go to bed early, especially for those who plan to take an employment physical examination. Abnormal transaminase may affect your employment.

3. Don’t drink alcohol. Wine contains alcohol. The ethanol in alcohol will be oxidized into acetaldehyde in liver cells, which may directly stimulate and damage liver cells, leading to elevated transaminase levels during liver function tests.
