The American Red Cross will have a blood-donation opportunity from 1-6 p.m. Saturday at First Baptist Church, 169 Church St. in Pembroke.

Donors of all blood types — especially those with types AB, O-negative, A-negative and B-negative — are needed to help ensure that blood products are available to hospital patients this summer. Individuals who are 17 years old (16 with parental consent), weigh at least 110 pounds and are in generally good health may be eligible to donate blood.

High-school students and other donors age 18 and younger also have to meet certain height and weight requirements.
