While the essay you may be asked to write may include information on blood collection or blood drives local to where you live, there is lots of information about giving blood which is true for all blood donation agencies and blood drives. The most general of guidelines require that a donor be at least sixteen years old and have a weight of at least 110lbs.
The essay could describe the requirements or the process of blood donation, as well as how the blood which is collected is used. In many cases the entire process of blood donation can run about an hour if not longer however the actual blood collection only takes about ten to fifteen minutes. The donation process usually begins with signing in and waiting in a waiting room until it is your turn to fill out the prerequisite information. The information is a basic overview and consent form of the process, as well as a questionnaire about your health background confirming that you are healthy for blood donation, and that your blood may be used for donation. After you fill out the forms a small blood test is done to make sure your body has enough iron and other minerals so that it is safe for you to donate. After all is said and done, you are set up to donate blood and after about ten to fifteen minutes, that part of the donation process is over, after making sure you are not light headed or going to pass out you are free to leave.
