When performing the measurement of blood alcohol concentration, the blood is enclosed in a test tube, and since the test tube is airtight, it does not normally evaporate. When measuring blood alcohol concentration, it is necessary to maintain the stability of the alcohol, so it is necessary to store the blood in an airtight test tube. If blood is collected by a healthcare professional and a proper test tube is selected, the alcohol in the blood will not evaporate and will not cause the alcohol concentration to change. The public is advised to minimize unnecessary alcohol consumption to prevent harm to the body. Reducing alcohol consumption can reduce the risk of diseases such as acute pancreatitis and hepatitis, thus safeguarding health. If you develop uncomfortable symptoms due to excessive alcohol consumption, it is recommended that you visit a hospital in time to receive standardized treatment under the guidance of a doctor.
