According to Redheaded Blackbelt, a Northern California blood bank issued an urgent appeal this week, saying “We’re low on O’s” and asking donors to come forward.
The report, published Sept. 9, 2026, describes the shortage of O blood types as pressing and frames the request as urgent. The blood bank is seeking volunteers who can donate to help rebuild supplies.
If you are able to give, the story advises contacting your local blood center to learn where and how to donate.
