With Thanksgiving comes a 15 to 20 percent drop in donor visits, and Bloodworks Northwest is responding by offering special hours through the holiday season to encourage donations. In addition to regular hours, Bloodworks Northwest will be open 8 a.m. to 4 p.m. Nov. 24, Dec. 21, Dec. 22, Dec. 29 and Jan. 5; 8 a.m. to 8 p.m. Dec. 23 and Dec. 30; and 8 a.m. to 2 p.m. Dec. 24 and Dec. 31. Bloodworks Northwest in Federal Way is located at 1414 S. 324th St., Suite B101. While all blood and platelet donors are welcome, there’s always demand for Type O blood and platelets. Donating blood takes less than an hour, and each donation can potentially save three lives. To make an appointment, visit schedule.bloodworksNW.org, or call 800-398-7888.
