Surface Antigen Expression in Trypanosomes
Dr. X's laboratory studies the parasite which causes trypanosomes, also known as sleeping sickness. This study will look at the effects of different surface antigens (proteins) produced by the parasites in human blood. The goal is to identify how different surface antigens are expressed by the parasites.
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All blood samples will be obtained by qualified technicians at the Medical Centre Blood Bank. 100ml of blood will be withdrawn from a vein in your arm. None of the procedures are experimental.
During the collection of blood, you may experience discomfort and bruising at the site of collection. To minimize these risks, you will be asked to lie down while an experienced technician collects the blood sample. You may feel light-headed after having blood drawn. If you feel faint, you should not get up and should notify a nurse.
Although you will not benefit directly from participating in this study, you will make a major contribution to the information known about sleeping sickness. In the future, others may benefit because scientists and doctors will learn about how parasites cause sleeping sickness and develop vaccines to prevent it.
A research assistant will keep a record of all blood draws in a secure database. Only the professional staff at the Medical Centre will know the identity of study participants.
You will be paid £5 for the time and travel required to give blood. If you feel that you have been injured as a direct result of participating in the study please contact Dr. X at 123-456-7890.
Your signature on this form means that you understand the information presented, and that you want to participate in the study. You understand that participation is voluntary, and you may withdraw from the study at any time.
