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: O positive blood type and pregnancy problems: Babies who have a different blood type to the pregnant mum’s O-blood type can lead to problems such as jaundice. If there is no Rh factor protein, the person is Rh- negative. As it turns out, women who have blood type O have a high risk of giving birth to infants with acute-level hyperbilirubinemia. If the Rh factor protein is present 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 characteristics. This process allows us to collect more red cells, which are the most critical part of an O Negative blood donation.įind out more about Targeting Your Type as an O Negative blood donor.Every person has a blood type, (O, A, B, or AB) and an Rh factor, either positive or negative. If your blood type is O and your baby’s type is A, B, or AB. Here are a few instances that can lead to this condition: If your blood type is B and your baby’s type is A or AB. During a double red cell donation, your blood is separated into its components during the donation process and the platelets and plasma portion are returned to you. In other circumstances, you might get an ABO incompatibility which will negatively affect your pregnancy. He says people with blood type O tend to. Some donors may qualify for double red cell donations. For example, he claims that blood type O is the oldest blood type, associated with ancestors who were hunter gatherers. That’s the type of donation you’ll find on most bloodmobiles.ĭuring whole blood donation, a pint of blood is taken from the donor and then later separated into its components – red blood cells, platelets and plasma. Research suggests that people with blood group O have a lower risk of heart diseases and memory problems (including dementia) than the rest of the population. You’re probably familiar with whole blood donation. Although the O-positive people can donate blood to people with any positive blood type, they can only receive blood from O positive and O negative (O) people. Low risk of pancreatic cancer: Compared to other blood types, people with blood type O have a lower risk of pancreatic. They can also donate blood to patients with O+, A+, B+, and AB+ blood types. Blood donation: O positive individuals can receive blood donors from both O+ and O. So, yes, we want your blood donation, we need it. Type O plasma can only be given to type O recipients. When someone with O Negative blood has an accident or undergoes surgery, they must receive an O- transfusion. But it is also the only blood type that can save O Negative recipients. O Negative blood can help save any and all trauma patients, premature babies, and cancer patients. In fact, O Negative blood is often used for premature infants and babies who need blood transfusions. Once doctors determine the patient’s blood type, they can switch to that type of blood.īut even then, O- blood is still an option. It is estimated 7 percent of the population has O- blood type while only 1% of the population has AB- blood.īut because the red blood cells of O- blood donors can be transfused into patients with any blood type, it is often the first choice for transfusions necessary in trauma situations. Myth: O Negative blood is the rarest blood typeĬontrary to popular belief, O- blood is not the rarest blood type.
