Can I drink alcohol the day before having my blood drawn?

After ingestion, it will be dispersed throughout the body and then transported to the liver through the blood for metabolism (detoxification). This detoxification process is very slow. Therefore, you should not drink alcohol the day before a blood test, especially for those who are doing liver function tests. Drinking alcohol the day before can easily lead to misdiagnosis.

How long after drinking can blood be drawn accurately?

At this time, the functions of various organs in the human body have been restored, and the various items detected in the examination are the most accurate.

What are the effects of drinking alcohol before having your blood drawn?

3. Abnormal liver function. Alcohol, also known as ethanol, is metabolized into acetaldehyde in the human body. Acetaldehyde has a degenerative or necrotic effect on liver cells.

Therefore, you must eat meat while drinking alcohol. Excessive intake of meat can easily lead to increased blood lipid concentration, and blood tests can easily misdiagnose hyperlipidemia.
