<bot>: Hi, Thanks for writing in. Voluntary bone marrow donation is an appreciable act and good to know that you are a willing donor for patients who are sick and in need. You need to ab an adult above 18 years in most countries and in good health. A small blood sample will be taken from you to determine your tissue type. This information is kept on the register of voluntary bone marrow donors. Should their be a requirement from a matching recipient then you will be informed about the need. The commonest procedure is peripheral blood stem cell donation. For this you might receive injections for 4 days to increase the circulating stem cells in your blood. On day 5 blood will be Chat Doctor.  This process takes place in the hospital and might take 3 to 5 hours and might be repeated the following day if required. Please do not worry.
