About 献血Web会員サービス ラブラッド
"Love Blood" is a membership service that connects the Japanese Red Cross Society and blood donors.
It is now possible to book blood donations and answer medical questions in advance.
You can avoid congestion at the blood donation venue, shorten your stay, and reduce contact opportunities, so you can donate blood more easily and safely.
Those who have been using “Labrad” so far can continue to use “Labrad” with the app.
You can donate blood from the age of 16, but if you are under the age of 16, you can receive information about blood donation by registering as a pre-member, and if you reach the age, you can make a reservation for the first blood donation.

The blood donation card you used so far is now an app.
Please present the barcode displayed on the app at the reception.
* Blood donation cards will not be issued or updated for those who present the app and accept it.
