Which patient might be diagnosed with physiologic jaundice? newborn baby elderly male individual with liver disease person with malaria

Rh antigens are separate from ABO antigens and were originally discovered in Rhesus monkeys. An Rh- mom carrying her second Rh+ fetus is at risk for hemolytic disease of the newborn. Anti-Rh antibodies are not automatically made, unlike the antibodies in ABO blood groups. An Rh+ mom carrying an Rh- fetus is at risk for hemolytic disease of the newborn. Anti-Rh antibodies are automatically made, like the antibodies in ABO blood groups.

In the case of pregnancy, the danger lies in a sensitized Rh- mother carrying an Rh+ fetus. How does this harm the fetus?

O- and AB+ are two of the least common blood types. What are some of the characteristics of these two blood types?

Clotting is necessary to mend breaks in circulatory vessels and to prevent extreme losses of blood, but it can also have detrimental effects if unregulated. Various factors may either enhance or inhibit this process.

When typing a patient's blood, agglutination occurred with anti-A and anti-Rh antibodies. What is this patient's blood type? B negative O positive A positive AB positive

What is the basis of the ABO blood groups? What is the basis of the ABO blood groups? antigens in the blood plasma Rh blood groups presence of anti-A and anti-B antibodies in the plasma presence or absence of A and B antigens on the surface of RBCs
