Washington residents have a chance to donate blood on Monday. The Washington High School Student Congress will host a blood drive Monday, February 24th from 8a.m. To 1p.m. In the Washington High School East Gym. According to the Red Cross, Types O negative and O positive are in high demand. Only 7% of the population are O negative. However, the need for O-negative blood is the highest because it is used most often during emergencies. Any questions should be directed to the Washington High School Office at 319-653-1100
