With the start of the new year, the American Red Cross is urging people to donate blood.
The organization is in critical need of O Negative blood, which is consider a universal donor, and B Negative blood, because it is so rare.
If you want to be a donor, you have to be at least 17 years old in Maryland and weigh at least 110lbs.
The process for general donations takes about 8 to 10 minutes and can save a life.
