During infancy‚ her body built anti-B antibodies since she lacked that antigen in her blood. If she receives a transfusion of blood type B‚ her body will already have the anti-B antibodies in place. Agglutination will occur as the anti-B antibodies bind and clump to the foreign B antigen. The red blood cells will be lysed‚ hemoglobin will be released into the blood stream‚ and these events could

Multiplication of contaminant bacteria in urine and interpretation of delayed culture. Abstract A prospective study of the bacterial populations of non-infected urine was mounted in an attempt to define the length of delay between voiding and analysis during which culture would not give false positive results due to the multiplication of contaminant bacteria present at the time of voiding. The findings suggest that culture of urine within four hours of voiding is likely to give a true indication
