Hoxworth Blood Center is putting out the call for blood and platelet donors.
Spokeswoman Alecia Lipton says area blood supplies are at a fragile level.
"Some of that is due to a very low donor turn out. We can blame part of that on cold and flu symptoms going around but also (Tuesday), due to the weather, we had some folks who were no-shows for their appointments," she says.
Lipton says all blood types are needed and platelet donors are especially important.
