it's described when you have two distinct cell population in blood. the presence of rare subgroups of A usually cause mixed field agglutination. for e.g the A3 subgroup. So when the patient with A3 subgroup is transfused with O blood group. mixed field reaction is seen. you will see some clumps among large numbers of cell which has absored the antibody on their surface but do not agglutinate.

What is clumping of red blood cells when they are mixed with antiserum?
Clumping of red blood cells when mixed with antiserum is known as agglutination. This reaction occurs when the red blood cells contain antigens that agglutinate with antibodies present in the antiserum. Agglutination is commonly used in blood typing to determine an individual's blood type.
What are the types of agglutination?
Direct agglutination Passive agglutination Reverse passive agglutination
What is an agglutination test?
An agglutination test is a test in which the use of a blood serum results in the agglutination of bacteria or foreign blood cells. The test is used to check for infection and to find pathogens as well as blood types.
What is the molecule in a person's body that is responsible for agglutination?
The molecule responsible for agglutination in a person's body is primarily antibodies, also known as immunoglobulins. These proteins are produced by B cells in response to foreign antigens, such as bacteria or viruses. When antibodies bind to these antigens, they cause clumping (agglutination), which facilitates the removal of pathogens by the immune system. Additionally, certain blood group antigens can also trigger agglutination in blood transfusions if incompatible blood types are mixed.
Is pregnancy test an antigen-antibody 'agglutination' or 'preciptation' reaction?
Its an agglutination test
When was Agglutination Metal Festival created?
Agglutination Metal Festival was created in 1995.
Is agglutination reaction affected by temperature?
Yes, agglutination reactions can be affected by temperature. High temperatures can denature antibodies, leading to reduced agglutination. It is important to perform agglutination tests at the recommended temperature to ensure accurate results.
What happens when two non-compatible blood types are mixed together platelet plug formation vascular spasm coagulation agglutination?
When two non-compatible blood types are mixed together, agglutination occurs. This is the clumping of red blood cells due to the interaction between antibodies in the recipient's plasma and antigens on the donor's red blood cells. This can lead to serious complications, including hemolysis and immune reactions, which disrupt normal blood flow and can damage organs. Other processes like platelet plug formation and coagulation may also be affected, but agglutination is the primary immediate response.
Who invented the agglutination tests?
The agglutination tests were developed by Karl Landsteiner in the early 20th century. Landsteiner's work on blood types and agglutination laid the foundation for modern blood typing techniques.
What is the clumping together of RBCs by antibodies?
coagulation- is not the correct answer! The correct answer from my "Anatomy and Physiology" book is Agglutination
What is the term for process of clumping?
agglutination
What is the difference between aggregation and agglutination?
Aggregation involves clumping of platelets while agglutination involves clumping of particles in the presence of antibodies.
