A few days after donating blood in Hefei, I learned by SMS.

The initial examination items before blood donation are: blood type, hemoglobin, transaminase and hepatitis B.

You can donate blood if you pass the preliminary examination.

After the blood is collected by a blood donation car or a blood donation house, it will be sent to the blood station laboratory at five or six in the afternoon. (Test items: blood type, hemoglobin, transaminase, hepatitis B, hepatitis C, AIDS, syphilis).

Most of the blood is fine, and the results will be available the next day. The blood in question will give the result on the third day.

According to experience, those who meet the requirements after donating blood will be notified by SMS the next day at the earliest and one week at the slowest.

If there is something wrong with the blood, you will call the blood donor himself.

After three days, you can almost always get a result by making a phone call. You can also go to any blood donation point in this city with your ID card or blood donation card. The system is networked.
