At any rate, it will make the recipient very ill and could even cause death. “If a patient receives the wrong blood type, it can result in a transfusion reaction with symptoms ranging from a fever to kidney failure. “Knowing what blood types are compatible with others when transfusing blood is very important,” Ortiz-Plaza said. When these situations happen and someone needs a blood transfusion, one of the main steps in the process is knowing the individual’s blood type. “So, if you have your health, celebrate it by giving blood to those who are not as fortunate and to help us be ready for those ‘just in case’ situations.” “It’s too late to donate blood when an emergency happens - people will need it immediately,” said Felix Ortiz-Plaza, Fort Leonard Wood Blood Donor Center quality assurance officer. So, military officials rely on the Armed Services Blood Program to ensure an ample supply is available for any situation. If a catastrophe or mass casualty situation happens, that number goes up drastically. The Department of Defense needs about 400 units of blood every day just to meet operational requirements. They all rely on caring individuals to donate blood to help them recover from their wounds and illnesses. This can affect the newborn baby, who may need treatment after birth.FORT LEONARD WOOD, Mo. - A child with a rare blood disease an adult injured in a vehicle accident someone with cancer and a warrior injured on the battlefield all have something in common. Sometimes an incompatibility may happen when the mother is blood type O and the baby is either A or B. This will prevent being sensitized if the baby is Rh positive. If the mother has not already been sensitized to Rh positive blood, she may be given Rh immunoglobulin (RhIg). Problems with the Rh factor happen when the mother's Rh factor is negative and the baby's is positive. If the father's genes are -, and the mother's are -, the baby will be: If the father's genes are -, and the mother's are + -, the baby can be If the father's genes are + - Rh-positive, and the mother's are + - Rh-positive, the baby can be: If a father's Rh factor genes are + +, and the mother's are -, the baby will have one + from the father and one - gene from the mother. If a father's Rh factor genes are + +, and the mother's are + +, the baby will have one + from the father and one + gene from the mother. ![]() More specifically, consider the following: If a person has the genes -, the Rh factor will be negative.Ī baby receives one gene from the father and one from the mother. If a person has the genes + -, the Rh factor will also be positive. If a person has the genes + +, the Rh factor in the blood will be positive. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over: Rh factors follow a common pattern of genetic inheritance. A baby may have the blood type and Rh factor of either parent, or a combination of both parents. The following are the possible combinations of blood types with the Rh factors: If there is no Rh factor protein, the person is Rh- negative. If the Rh factor protein is on the cells, the person is Rh-positive. The Rh factor is a protein that is found on the covering of the red blood cells. The blood type is found as proteins on red blood cells and in body fluids. The blood type and the Rh factor simply mean that a person's blood has certain specific features.
