Sanidade calls to donate blood due to the low reserves of groups A positive and 0 negative

The Organ and Blood Donation Agency (ADOS) calls on citizens to donate blood after verifying that the reserves of groups A positive and 0 negative are at low levels. The only groups that are at a good level are B negative, AB positive, and AB negative, while A negative, 0 positive, and B positive are normal. Galician hospitals need about 500 daily donations to carry out their activity.
