I didn't receive any notice after donating blood, indicating whether the blood was qualified or unqualified, but I didn't seem to write the contact information.

Under normal circumstances, the blood station will send a text message to the mobile phone number reserved by the blood donor to inform that the blood is qualified. If the blood is unqualified, you will call me.

If you don't write your contact information, the blood station can't inform you.

It is best to hold a blood donation card or ID card to any local blood donation point to inquire about the qualification of blood use and fill in the contact information.
