Houchin Community Blood Bank is running very low on blood and is urgently asking for donations ahead of the weekend.
There is less than a three day supply of A+, O-, O+, B+ and B- blood going into the weekend, Houchin said Friday.
The flu made it difficult for supply to keep up with demand.
If you can donate, Houchin is open until 6 p.m. on Friday. On Saturday, Houchin is open 8 a.m. to 2 p.m.
Both donor centers at 5901 Truxtun Avenue and 11515 Bolthouse Drive will be open.
