When babies are born, a Coombs (or Direct Antibody Test) is performed to determine the probability of a newborn becoming anemic or jaundiced. This can happen when the mom’s blood enters the baby’s bloodstream during birth. If the mom and baby have different blood types, this may be an issue. Julia and Harjit are expecting their first child in a couple of weeks. Julia has type O blood and Harjit has type AB blood. Does she have any reason to be concerned? Determine the percent probability for the child's blood type.

• Yes, there is a high probability of concern.

• No, there is no probability of concern.

• There is a moderate probability of concern.

• The probability cannot be determined.

Which type of white blood cell matures into macrophages and is responsible for fighting specific infections and removing dead tissue?

• Lymphocyte

• Monocyte

• Basophil

• Eosinophil
