A successful blood donation does not mean that the liver function is normal. The result of qualified blood donation is only used to determine whether the donor is suitable to donate blood, and is not applicable to the diagnosis of the donor’s health condition. Before donating blood, donors need to undergo a full body examination and blood test, and whether the liver is healthy or not needs to be tested for HIV, syphilis, viral hepatitis and other programs. The healthy developmental state of the liver or the diagnosis of the disease is usually judged by the clinician based on the patient’s personal symptoms related to the disease, such as whether there are symptoms of nausea, vomiting, diarrhea, etc., whether there has been facial jaundice, darkening of the face, or vague pain in the liver area and other discomforts, and whether there are clinical manifestations such as lethargy, fatigue, irritability, and irritability in the normal course of the day. In addition, it is also necessary to combine blood tests and imaging tests such as ultrasound, CT and MRI to make a comprehensive determination. Before donating blood, the blood donation station will conduct bloodborne disease testing on the donor’s blood in accordance with national regulations, and the blood that passes the test will be used in the clinic. The testing program is blood-borne disease screening, with fewer items, significantly less than the liver health test and imaging tests in hospitals, so a successful blood donation does not mean that the liver function is normal.
