Add one drop of red cell suspension in cach test tube. Patients may feel faint after any type of blood drawing. Agglutination reaction is the reaction in which soluble antibody interacts with particulate (insoluble) antigen in the presence of specific electrolytes at a particular temperature and pH, resulting in clumping of particles. Unwashed RBCs in case of multiple myeloma may give false-positive results because of rouleux formation. It has no antigen and has antibodies anti-A and anti-B. Also, drying of the reaction mixture at the edges causes aggregation that may be mistaken for agglutination. Typically, analysts will first use the Appearance, Behavior, and Context (ABC) Approach to Bloodstain Verification because it can be impractical to test an entire crime scene for blood. Disadvantages It is not recommended as a routine tests because it is not reliable for weakly reactive antigens on cells and for serum typing tests with low titer anti-A/anti-B.

If this is done by mistake, 80% chance are developing anti-D antibodies in the transfused person. It has the advantages of speed, low reagent consumption, and high-throughput analysis.
