Several short messages about unqualified blood donation

China's Blood Donation Law stipulates that healthy citizens are encouraged to donate blood without compensation. At the same time, after blood donation, the blood bank will make all kinds of comprehensive inspections on the donated blood, and if there is any unqualified situation, it will call the blood donor. Common unqualified blood conditions are as follows: First, the concentration of transaminase in blood donors increases, whether it is alanine transaminase or aspartate transaminase, as long as the concentration of transaminase increases, it is generally unqualified blood. Second, carriers of hepatitis B surface antigen are positive. If hepatitis B surface antigen is positive, the blood in this case is also unqualified. There are also people who are positive for hepatitis C antibody, HIV antibody and syphilis antibody. The blood donated by these people is unqualified, because these diseases can be transmitted through blood. If you give this blood to others, it may cause the spread of these diseases, so unqualified blood donation is the common reason above.

Whether a blood donor's blood is qualified or not requires a series of tests, including blood routine, liver function, infection and so on. Blood routine mainly depends on whether white blood cells, hemoglobin and platelets are normal. If one of them is unqualified, you can't donate blood. Liver function mainly depends on transaminase and bilirubin. If there is an increase, it means that there is liver damage recently and it is not suitable for blood donation. The eight items of infection are mainly to detect whether blood donors have four infectious diseases: hepatitis B, hepatitis C, syphilis and AIDS. If there is an infectious disease, blood donation is taboo.
