This leads to a markedly decreased red blood cell count and hematocrit and markedly elevated mean cell volume and mean cell hemoglobin concentration. [5]: 32–3 Red cell agglutination also interferes with routine methods for blood typing and blood compatibility testing, which rely on agglutination reactions. People with red cell agglutination ...
This image explains agglutination in the blood. Agglutination is the clumping of particles. The word agglutination comes from the Latin agglutinare (glueing to).. Agglutination is a reaction in which particles (as red blood cells or bacteria) suspended in a liquid collect into clumps usually as a response to a specific antibody.
A slide coagulase test is run with a negative control to rule out autoagglutination. Two drops of saline are put onto the slide labeled with sample number, Test (T) and control (C). The two saline drops are emulsified with the test organism using a wire loop, straight wire, or wooden stick.
An overview of the different components included in the field of chemical biology. Chemical biology is a scientific discipline between the fields of chemistry and biology.The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems.

The direct and indirect Coombs tests, also known as antiglobulin test (AGT), are blood tests used in immunohematology.The direct Coombs test detects antibodies that are stuck to the surface of the red blood cells. [1]
Agglutinin might also be associated with diseases of which the most common is an autoimmune disease known as cold agglutinin disease.In cold agglutinin disease, the body produces agglutinins or antibodies that coagulate erythrocytes and lyse them at room temperature or lower.
Bioanalysis is a sub-discipline of analytical chemistry covering the quantitative measurement of xenobiotics (drugs and their metabolites, and biological molecules in unnatural locations or concentrations) and biotics (macromolecules, proteins, DNA, large molecule drugs, metabolites) in biological systems.
Structural model of an antibody molecule. Rounded portions indicate antigen binding sites. In an antibody, the Fab (fragment, antigen-binding) region is formed from the amino-terminal end of both the light and heavy chains of the immunoglobulin polypeptide.
