Why is testing for Rh antigens and antibodies different from ABO testing?
abo blood group system was discovered in 1901 and rh was discovered in 1940.
Who discover Rh blood grouping in which year?
landsteiner n wiener discovered rh factor in 1940..........
Which animal species was RH first discovered?
Rhesus monkeys
The term Rh is used because the antigen was first discovered in the blood of a?
Rhesus monkey.
Is their such a thing as blood d?
I assume what you are talking about is D antigen in Rh (Rhesus) blood group system. Rh blood group system is the most important blood group system after ABO blood group system (i.e. type A (AA, AO), type AB, type B (BB, BO), type O (OO) ). The Rh blood group system consists of 50 defined blood-group antigens and the 5 antigens D, C, c, E, and e are the most important. The commonly-used terms Rh factor, Rh positive and Rh negative refer to the D antigen only. Rh factor (Rh- and Rh + depending on D antigen neg/pos) is important for blood transfusion and prevention of hemolytic disease of the newborn or erythroblastosis fetalis (basically the baby and mom have different blood type - Rh- and Rh+ and cause severe immune response - fatal to the newborn)
How did scientists come up with the name Rh factor?
The antigen was first discovered in the blood of Rhesus monkeys.
With a Rh plus mother and a Rh- fetus will either develop antibodies against Rh antigens?
no when Rh negative blood from the fetus interacts with Rh+ blood of the mother there will be no antibodies produced due to absence of antigen on the Rh- blood cells and when Rh positive is mixed with Rh negative blood of fetus no response is produced due to the fact that the fetus has an underdeveloped immune system
Where was the Rh factor first discovered?
Rhesus monkey In fact, the scientific name of the monkey is "macacus rhesus"
What chemical does Rh stand for?
Rh is the chemical symbol for rhodium.If you meant "Rh" as in "Rh factor" in blood, it doesn't stand for a chemical. It stands for "rhesus", the kind of monkey (actually a macaque) the researchers who initially discovered it used to produce the serum.
What causes the production of Rh antibodies?
Exposure to the Rh (or D) antigen. Most common in mothers who are Rh- who have a child that is Rh+. The mothers immune system will produce Rh antibodies and the blood cells of the NEXT Rh+ baby could be attacked during birth. Rh- mothers are given Rhogam to prevent this from happening. I know this is more than you asked for but every test question dealing with Rh asks something about this it is commonly called hemolytic disease of the newborn
What does Rh positive blood mean and how is it differerent to RH negative blood?
Your blood type is determined (genetically) by the presence or absence of specific surface antigens on the membrane of the RBC. The most important RBC surface antigens are A, B and Rh.Blood can be either Rh positive(Rh+) or Rh negative (Rh-) depending on the presence (Rh+) or absence of the Rh antigen (Rh-) on the surface of the cell.Unlike the ABO system, type Rh- blood does not normally carry anti-Rh antibodies, unless the individual has been sensitized by previous exposure (usually pregnancy).The most common blood type is O+.
Can a child born with rh negative blood type be the offspring of an o positive father?
It depends on the genotype of the Rh+ parent. If that person is heterozygous, then yes there is a 50% chance of an Rh- baby.Father's Group (negative)Mother's Group (positive heterozygous)Rh +Rh -Rh -Rh +, Rh -Rh -, Rh -Rh -Rh +, Rh -Rh - Rh -http://www.bloodbook.com/inherited.htmlIf the positive parent is homozygous, the baby will be positive:Father's Group (negative)Mother's Group (positive homozygous)Rh +Rh +Rh -Rh +, Rh -Rh +, Rh -Rh -Rh +, Rh -Rh + Rh -
