For Patients: Blood Donation FAQs
Blood stored longer than three weeks becomes less flexible and less able to fit in the body’s smallest capillaries. Most of the blood transfused during the study had been stored for less than 35 days, so it’s still unknown whether blood stored for 35–42 days would be equally safe to use in these patients. Future studies will also need to examine whether red-cell storage duration affects the health of patients who need transfusions for other reasons. 42 days Red cells are stored in refrigerators at 6ÂºC for up to 42 days.
Blood can be stored in a Blood Bank validated cooler for up to 6 hours. HOUSTON– Donating blood is an act of kindness towards your man, but did you know it had a shelf life? That’s right, every bag of blood has an expiration date and it doesn’t last as long as you would think. “Blood does expire after 42 days,” said Joshua Buckley of the Gulf Coast Regional Blood Center. Given the relatively rapid degradation of blood after it’s drawn, all samples should be promptly tested, refrigerated for short-term storage, and frozen for long-term storage. For specimen integrity and accurate test results, blood samples must be stored in specific ways.
How Are Platelets Stored?
Platelets are stored at room temperature for up to 5 days. They must receive constant gentle agitation to prevent them from clumping. Whole blood is used to treat patients who need all the components of blood, such as those who have sustained significant blood loss due to trauma or surgery. Blood drives hosted by companies, schools, places of worship and civic organizations supply roughly half of all blood donations across the U.S. If all blood donors gave three times a year, blood shortages would be a rare event. Shortages of all blood types happen during the summer and winter holidays.
Any company, community organization, place of worship or individual may contact their local community blood center to host a blood drive. You cannot get AIDS or any other infectious disease by donating blood. Granulocytes, a type of white blood cell, roll along blood vessel walls in search of bacteria to engulf and destroy. Test results are transferred electronically to the processing center within 24 hours.
