blood test- a serologic analysis of a sample of blood agglutination test- a blood test used to identify unknown antigens; blood with the unknown antigen is mixed with a known antibody and whether or not agglutination occurs helps to identify the antigen; used in tissue matching and blood group...
(the section forming a ring of a dark color) are constant as a rule, all the precipitates of the pale color formed on the inside of the dark color ring centering at the peak part indicate the agglutination and decrease and disappear toward the center thereof thereby expressing distinctly the...
Fortunately, a simple test can indicate your blood type, revealing clues about your health, providing critical information before a medical procedure, and even telling you how valuable you are as a blood donor. Find out how blood typing works, learn why this process is critical, and discover t...
All agglutination showed that two kinds of agglutination blood group containing A and B were AB type. No agglutination The results showed that A and B were not detected in the samples, and the blood group was O type. The test is sensitive and rapid, requiring less material, but the ...
Using Agglutination to Determine the Blood Type: Agglutination describes the clumping of particles and results from an antigen being mixed with its corresponding antibody. For example, agglutination will occur in a blood test if blood type A interacts with Anti-A antibody serum. ...
4(a). We therefore consider that waveguide-mode sensor-based hemagglutination detection is more sensitive and accurate than a visual test. Weak agglutination reactions, such as a reaction between weak-A RBC antigen and anti-A, sometimes appear as false negative during the blood testing. Our ...
Landsteiner discovered theagglutinationphenomenon ofnormal humanblood and found that there are substances in the blood, antigens and antibodies, that induce clumping of red cells when cells of one type are added to those of another type. On the basis of these reactions, he identified three blood...
Blood type disagreement during pregnancy: What you need to know Rh incompatibility occurs when a pregnant mother with Rh-negative blood comes into contact with Rh-positive blood from her fetus, leading to the development of Rh antibodies in the mother's body. This causes the fetus to become an...

The answer to that question has to do with the function of the blood type proteins. In the early 1900s, scientists were attempting to transfuse human blood from one person to another. This was a way to save lives when a patient had lost too much blood. A physician named Karl ...
