Hemagglutination?
On the surface of red blood cells Take A type blood, for instance. It has antigens against B type blood contact on its cell surface.
It is the measures of the ability of soluble antigen to inhibit the agglutination of antigen-coated red blood cells by antibodies. In this test, a fixed amount of antibodies to the antigen in question is mixed with a fixed amount of red blood cells coated with the antigen (research on passive hemagglutination). Also included in the mixture are different amounts of the sample to be analyzed for the presence of the antigen. If the sample contains the antigen, the soluble antigen will compete with the antigen coated on the red blood cells for binding to the antibodies, thereby inhibiting the agglutination of the red blood cells.
the white blood cells the white blood cellsAntigens are generally fragments of protein or carbohydrate molecules. There are millions of different antigens and each one has a unique shape that can be recognised by the white blood cells of your immune system. The white blood cells then produce antibodies to match the shape of the antigens. The antigens on the surface of pathogenic cells are different from those on the surface of your own cells. This enables your immune system to distinguish pathogens from cells that are part of your body. Antigens are also found on the surface of foreign materials like pollen, pet hairs and house dust where they can be responsible for triggering hay-fever or asthma attacks.
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
mxd stand for mixed cells in t he blood
yes,it will be mixed in blood
agglutination
There are two ways of measuring Rheumatoid factor in bloodThe Agglutination tests. In this test blood is mixed with minute latex beads that have been covered with human antibodies. If there is RF, the beads clump together or agglutinate. Another agglutination test uses sheep's blood that has had its red blood cells covered with rabbit's antibodies, then mixes the blood being tested with it . If there is RF in the blood sample, the red blood cells clump together. This method is often used to confirm the presence of RF.The Nephelometry test. In this test a blood sample is mixed with antibodies cause the blood to clump if RF is present. A light beam from a laser is directed through the sample containing the mixture and the amount of light blocked by the blood sample is measured. The more clumping that occurs, the cloudier the sample and less light to pass through the tube.
The type B blood has an antigen on the red cells identifying them as B type cells. The type A blood of the recipient contains antibodies that bind to B type antigens. These antibodies will cause the red cells of the blood in the transfusion to stick together forming solid lumps in the blood, preventing it from flowing.
If the child is Rh positive, and it is the mother's second child, the mother's antibodies will attack the child's red blood cells when the blood becomes mixed during labor. An injection called RhoGAM will be administered to the mother right before delivery to prevent any attack of fetal red blood cells.
MXD test blood is the measure of mixed cells in the blood. Also meaning, the measure of Lymphocytes in the blood.
