An extra 9,500 donations of O positive and O negative blood donors are needed in the next seven days to ensure Lifeblood can continue to meet the needs of patients across the country.
You’ve reminded me I should donate again, its been a while… though one small correction, O- is not the most common at all. It makes up under ~10% of the population as a rule: https://www.healthdirect.gov.au/blood-types
O-type is O- and O+. That’s a hyphen, not a negative sign.
O- is definitely the most valuable, since it can be given to anyone. But O+ isn’t far behind, since it can give to all the positive types, which is 86% of people, according to your source.
