Surface Antigen Expression in Trypanosomes
You are invited to participate in this study by giving blood on a voluntary basis, but no more than five times in an eight week period. The research project is anticipated to continue for four years.
All blood samples will be obtained by qualified technicians at the Medical Centre Blood Bank. 100ml of blood will be withdrawn from a vein in your arm.
Although you will not benefit directly from participating in this study, you will make a major contribution to the information known about trypanosomiasis, also known as sleeping sickness. In the future, others may benefit because scientists and doctors will learn about how parasites cause sleeping sickness, and will develop vaccines to prevent it.
You will be paid £5 for the time and travel required to give blood.
Your signature on this form means that you understand that participation is voluntary, and you may withdraw from the study at any time.
