Blood lines: Where our blood donations go

There are an estimated 29,000 registered blood donors in Snohomish County. Each year, about 26,400 units are collected at the Puget Sound Blood Center's Everett donation center, one of two collection sites in Snohomish County for the non-profit agency. The other is in Lynnwood, where about 21,015 units are collected annually.

The Puget Sound Blood Center has 11 collection sites in Western Washington, spread between Vancouver and Bellingham.

Donations typically decline during holiday periods. So last year a special appeal was made for regular donors to give blood during December and the first week of January. That helped prevent a shortage when snow and ice later prevented people from donating, said David Larsen, spokesman for the Puget Sound Blood Center. "It's a very dynamic process to manage a stable supply," he said.

The average annual amount of blood collected by the Puget Sound Blood Center is about 200,000 units. About 90 percent of donations are whole blood.

The cost of collecting, testing, processing and delivering a unit of blood, which is equivalent to about a pint, is about $250.

The Puget Sound Blood Center serves 70 hospitals and clinics in 14 counties. In a typical month, it ships about 12,000 units to hospitals in King County and about 5,500 units to other hospitals in Western Washington.
