Oklahoma Blood Institute is teaming up with two Oklahoma attractions to help boost the blood supply this spring.

Those who donate blood with Oklahoma Blood Institute in March will receive a free T-shirt and their choice of one free entry to the Oklahoma City Zoo or the National Cowboy & Western Heritage Museum. Tickets may be used throughout the remainder of the year.

March is historically a challenging month for blood donations as many people are travel for spring break and enjoy the warmer weather. These factors have a negative impact on the blood supply. OBI needs 1,200 donors a day to maintain an adequate blood supply.

Anyone who is healthy and 16 years old* or older can give blood. Donation takes only about an hour, and one donation saves up to three lives. Appointments to donate can be made online at obi.org or by calling 877-340-8777. Walk-ins are also welcome.  16-year-olds must weigh at least 125 pounds and provide signed parental permission; 17-year-olds must weigh at least 125 pounds; 18+ year olds must weigh at least 110 pounds. Photo ID required.
