Blood type grouping is very important because if infection occurs then the wrong grouping was used and then we have a problem. Transfusions, etc. It is essential to correctly identify the blood group.

Instead of using antisera for blood grouping , pooled known RBCs are used. the process is serum typing.so serum of patient whose Rbcs are auto aggluting is used.
Lectins are proteins that can specifically bind to carbohydrates and are used in blood grouping to identify blood types. They agglutinate red blood cells by binding to specific sugar molecules on the surface of the cells, allowing for differentiation between various blood groups such as A, B, AB, and O. This property is exploited in laboratory tests to determine an individual's blood type, which is crucial for safe blood transfusions and organ transplants. By mixing a blood sample with specific lectins, the resulting agglutination pattern reveals the blood group.
Observing trends in physical characteristics and grouping them in a way that demonstrates gradual change.
In forward grouping, serum is used to determine the presence of specific antigens on the surface of red blood cells. By mixing a patient's red blood cells with known antibodies in the serum, clinicians can observe agglutination reactions that indicate the blood type. This process helps identify compatible blood for transfusions and ensures patient safety by preventing transfusion reactions. Ultimately, the serum acts as a key tool in blood typing and transfusion medicine.
Methods used to separate blood donations are; # Centrifugation # Filtration The main separation method used is Centrifugation.
Legal investigations may require typing of blood or such other body fluids as semen or saliva to identify criminal suspects. In some cases typing is used to identify the victims of crime or major disasters.
A dry mount slide is a slide that has no liquid or cover slip. This type of slide is commonly used for observing solid specimens under a microscope.

A blood smear is a sample of blood that is spread thinly on a glass slide, stained, and examined under a microscope. It is used to evaluate the number, morphology, and size of different types of blood cells such as red blood cells, white blood cells, and platelets. This test helps in diagnosing various blood disorders and infections.
