Further, there’s a general process that donors go through when blood is donated. According to the Red Cross, blood donors must be in good health and at least 17. However, 16-year-olds can donate blood with the permission of their parents in some states. In addition, donors must weigh at least 110 pounds.
Blood donors undergo a quick physical exam. In this process, temperature and blood pressure is taken and the pulse and hemoglobin will be measured. Prepare for a donation by consuming ample fluids before donation and eat a healthy, iron-rich meal.
You’ll also need to bring a list of any medications that you take as well as an ID. A driver’s license or two other forms of ID are acceptable. You will be asked about health history, and blood is tested for various diseases, like HIV, hepatitis and West Nile virus.
