After donating blood, I received a message saying that my blood was unqualified. What happened?

Before donating blood, there was a registration questionnaire, which listed many questions such as menstrual period and medical history. Usually, as long as you fill in this form truthfully, you can isolate most unsuitable blood donors.

Before donating blood, there is a physical examination, a heart rate pulse, and blood sampling to detect three indicators of blood: blood type, red blood cells (anemia) and transaminase.

These three items are all right, so we will enter the blood collection link. After the blood collection is completed, it will be sent to the blood center for other indicators within eight hours, and the domestic reagents and imported reagents will be used for two tests.

After passing the examination, they registered in the blood bank and sent a thank-you letter to the blood donors.

If the test is unqualified, the center staff will secretly discard the blood and call the blood donor.

In view of what you have stated, I suggest that you call back to the blood center or go in person. If you have any questions, don't delay the treatment.
