Typically a pregnant woman gets tested for immunity to rubella (rubella IgG antibodies), and a positive test means she has adequate protection against rubella, which can cause birth defects. In contrast, you report a gest for rubeola antibodies. In order to interpret the test, more information is needed regarding the type of test done (IgM versus IgG). Please check with your health care provider for information specific to your situation.
Individuals with blood type A positive have antibodies against blood type B antigens. This means their immune system reacts against blood from individuals with blood type B if they were to receive a transfusion containing type B blood.
If an Rh negative person is exposed to Rh positive blood, their immune system may produce antibodies against the Rh antigen. Upon subsequent exposure to Rh positive blood, these antibodies can attack and destroy the Rh positive red blood cells, leading to a condition called hemolytic disease of the newborn (HDN) in pregnant women or a transfusion reaction in non-pregnant individuals.
We don’t yet know the answer to this question. We do know that an rh neg female who has been exposed to rh positive blood through a birth or miscarriage will form antibodies against rh positive blood and on becoming pregnant again with an rh positive fetus will have antibodies that will attack the fetus which may cause numerous problems.
A person who is Rh negative may have antibodies if he or she has been exposed in the past to Rh positive blood. Rhogam will prevent this sensitization in a pregnant woman with negative blood carrying an Rh positive baby.
Positive antibodies indicate that the immune system has produced antibodies in response to a specific infection or vaccination. These antibodies help protect the body against future encounters with the same pathogen by recognizing and neutralizing it.
The blood types of mother and father have nothing to do with a child being abnormal. A mother with Rh negative blood (for instance, A negative) who becomes pregnant with a baby with Rh positive blood (A positive) can develop antibodies against the baby, but there is treatment for this.
Blood type is irrelevant to whether or not you can get pregnant.
A person who is B positive will have B antigens on their red blood cells and anti-A antibodies in their plasma. This blood type is compatible for transfusion with B positive, B negative, O positive, and O negative blood types.
Syphilis is diagnosed with a blood test, which is determined positive if the antibodies to the infection are found in the blood.
Blood Type O has no Anti Rh factors. O+ blood is positive for Rh Antibodies.
If the antibodies in Rh negative pregnant mothers attack the blood cells of an Rh positive baby, the baby may be damaged by a low blood cell count. This hemolytic anemia can be prevented by the use of Rhogam in each pregnancy in an Rh negative mother.
If an Rh negative woman is pregnant with an Rh positive fetus, her body will produce antibodies against the fetus's blood, causing a disease known as Rh disease
