The American Red Cross faces a blood shortage and has issued an emergency call for eligible individuals of all blood types to donate at the 31st annual Jaffa Shrine Blair Media Blood Blitz from 8 a.m. to 8 p.m. Tuesday. The Jaffa Shrine is at 2200 Broad Ave.

There is less than a three-day supply of most blood types.

All presenting donors will receive a $10 e-gift card, courtesy of Suburban Propane, and be treated to a grill-out. Walk-ins are welcome. Appointments are encouraged.

Download the American Red Cross Blood Donor App, visit redcrossblood.org or call 800-RED CROSS (800-733-2767) to make an appointment or for more information.

A blood donor card or driver’s license or two other forms of identification are required. Individuals who are 17 years of age or 16 with parental consent, weighing at least 110 pounds and in generally good health may be eligible to donate blood. There are height and weight requirements.

Blood and platelet donors can save time at their next donation by using RapidPass to complete their pre-donation reading and health history questionnaire online, on the day of their donation, before arriving at the blood drive. To get started, follow the instructions at redcrossblood .org/RapidPassor use the Blood Donor App.
