Why is testing for Rh antigens and antibodies different from ABO testing?
Testing for Rh antigens and antibodies is done to determine the presence of the Rh factor in the blood, which is a separate system from the ABO blood group system. Rh testing is important for determining compatibility in blood transfusions and during pregnancy. ABO testing, on the other hand, evaluates the presence of A, B, AB, or O antigens on red blood cells to determine blood type.
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.
What is the purpose of the RH wire in a thermostat?
The purpose of the RH wire in a thermostat is to connect to the heating system in order to control the heating function of the HVAC system.
What is the purpose of the RH wire on a thermostat?
The purpose of the RH wire on a thermostat is to provide power to the heating system.
Is the fisher system CDE cde for Rh only?
The Fisher system, specifically the CDE (Cohen-Doyle-Ellis) system, is designed for classifying blood group antigens, including those of the Rh system. However, it is not exclusive to Rh antigens; it encompasses a broader range of blood group systems. The CDE notation is primarily used to describe the Rh antigens, but it also accommodates the complexity of other blood groups. Thus, while it plays a significant role in Rh classification, it is not limited to Rh only.
How did scientists come up with the name Rh factor?
The antigen was first discovered in the blood of Rhesus monkeys.
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)
Why there is no reaction against Rh factor on first transfusion?
There is no reaction against the Rh factor during the first blood transfusion because the recipient's immune system has not yet been sensitized to the Rh antigens. When Rh-positive blood is transfused into an Rh-negative individual for the first time, their body does not have pre-existing antibodies against the Rh factor, allowing the transfusion to occur without an immediate immune response. However, if an Rh-negative person is exposed to Rh-positive blood again, their immune system may recognize the Rh antigens and mount a reaction.
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
How can I integrate an RC and RH thermostat into my home heating system?
To integrate an RC and RH thermostat into your home heating system, you will need to connect the RC wire to the cooling system and the RH wire to the heating system. Make sure to follow the manufacturer's instructions and consult a professional if needed to ensure proper installation and functionality.
