Blood samples in vacutainers. These samples have been routinely collected during blood donation by volunteer donors. The blood will be screened for blood diseases,such as hepatitis and HIV,and typed to determine the blood group. This is necessary to ensure that blood given to patients in transfusions is clean and of the correct blood group. Transfusions may be necessary when patients have lost blood,for example during surgery or after accidents | |
