Donate blood, no texting.

Do not rule out the loss of text messages. Generally, blood collection and supply institutions have enquiry telephones. Call to check whether it is qualified.

In addition, even if the blood center there is unqualified, it is not really unqualified. Because in order to ensure the absolute safety of blood for clinical use, the reagents and test standards used in blood centers are more sensitive and stricter than clinical ones, and there is a certain false positive rate. If the blood center says it is unqualified, it should go to the clinical hospital for re-examination. If there is no problem in the clinical hospital, it means there is no problem.
