incompatibility group of antigens, determined by heredity and usually present in human red blood cells, that may cause hemolytic reactions during pregnancy or after transfusion of blood containing this factor into someone lacking it.
a substance found on the red blood cells of RH positive individuals
a type of protein that may or may not be present on a person's red blood cells.
protein on surface of red blood cells in some blood types (Rh+) and absent in others (Rh-). Can cause erythroblastosis fetalis in second pregnancy if fetal/maternal blood of opposite groups mix on first pregnancy.
A protein that is found on red blood cells. If the Rh factor protein is present on the cells, a person is Rh-positive. If there is no Rh factor protein, the person is Rh-negative. An Rh-negative woman carrying an Rh-positive fetus may produce antibodies that attack the fetus's blood.
A substance present in the red blood cells of most people. If the Rh factor is present in the blood of a fetus but not in that of the mother, her system produces antibodies that may enter the bloodstream of the fetus and indirectly damage the brain.
An agglutinogen that may be present (Rh-positive) or absent (Rh-negative) from the surfaces of red blood cells.
A marker found on the red blood cells. If you have the marker you are Rh positive; if you are missing the Rh factor you are Rh-negative. Antibodies to the baby's blood can form if you are Rh-negative and are carrying an Rh-positive baby.
A group of antigens present in the red blood cells.
A blood factor located in red blood cells. Eighty-five percent of the population carry the blood factor and are Rh positive. Fifteen percent are missing the factor from their blood cells and are Rh negative.
a blood group antigen possessed by Rh-positive people; if an Rh-negative person receives a blood transfusion from an Rh-positive person it can result in hemolysis and anemia
A protein found on the red blood cells of many people. The protein is named for the Rhesus monkey, as it was first discovered on their red blood cells. The Rh positive blood type contains the protein; the Rh negative blood type does not.
A protein found in the blood serum of people who are Rh-positive.
a group of antigens in the blood. Some people lack the Rh factor and are designated as Rh negative.
Blood group, which when positive is Rh+, and when not present is Rh-.
A hereditary factor determined by a blood test. Having this factor is called Rh positive; not having it is called Rh negative.
A group of antigens in the blood. Persons who have the Rh factor are called Rh positive, and those who do not have the factor are Rh negative.
A protein D found on the surface of red blood cells. Those lacking the protein are Rh negative, while those who have it (the majority of the population) are Rh positive.
Any of one or more genetically determined antigens usu. present in the red blood cells of humans and higher animals and capable of inducing intense immunogenic reactions -called also rhesus factor.
any of one or more genetically determined antigens present in the red blood cells of most persons and capable of inducing intense immunologic reactions. Some women develop a sensitization to Rh during pregnancy. If a woman is Rh negative and her husband is Rh positive, she is a candidate for Rh incompatibility problems. After the first pregnancy, the Rh factor enters the Rh-negative mother's circulatory system during the delivery (or miscarriage) of a child who has inherited the Rh factor from his father. The mother's body then produces antibodies against it. If she becomes pregnant with another Rh-positive baby, the antibodies cross the placenta and attack the baby's red blood cells, causing mild to serious anemia in the baby. The medication Rhogam is given to prevent these problems.
Every person has a blood type, (O, A, B, or AB) and an Rh factor, either positive or negative. The Rh factor is a protein that is found on the covering of the red blood cells. If the Rh factor protein is present on the cells, the person is Rh positive. If there is no Rh factor protein, the person is Rh negative.
Rh Factor is a protein found in the blood serum. If the woman has this substance, she is Rh-positive, if she does not have this, she is Rh-negative. An Rh-negative woman carrying an Rh-positive baby may produce antibodies against the baby. When a baby's blood type is incompatible with the mother's, the pregnancy needs to be carefully monitored, because the result can be mild or severe damage or death to the baby from Rh disease.
