How do you know if your blood has been used after donating blood?

Blood type, transaminase, hemoglobin and hepatitis B will be tested before blood donation, and blood will be collected after the initial test is qualified.

After blood donation, hepatitis C, AIDS, syphilis and the above four items will be added, and two or more reagents from different manufacturers or batches will be tested for more than two times before they are completely qualified for clinical use.

Generally, after the blood test is qualified, the blood donors will be notified according to the contact information (most commonly SMS) filled in by the blood donors.

If it is unqualified, it will inform you of the unqualified items, because the blood donation test is stricter than the hospital's disease standard, and the hospital test shall prevail.

If you don't receive the notice, the blood donor himself will go to any blood donation point in the blood donation city after one week, which can be found on the intranet.
