Antigen and antibody detection of red blood cells. The specific reaction principles expressed in the form of a swarm of red blood cells. (Hemagglutination) or hemolysis. (Hemolysis) by using standard in vitro intermediary salt. The way such tests are used to detect antigens of red blood cells (red cell typing) Screening for antibodies in serum (antibody screening test) or detect certain types of antibodies (antibody identification), as well as test it. Compatibility of blood prior to patient. (Crossmatching) a major factor that affects the detection of interactions between antigens and antibodies of red blood cells is the clear liquid before adding antihuman globulin serum and shaking techniques to read. This requires expertise and highly experienced. The reaction yielded weakly positive (weak reaction), so have developed gel test used for the detection reaction. Guided by the principle that a gel filter erythrocyte agglutination reaction by the gel to be spun in a reasonable speed. Red blood cells that are swarming to remain on top of the gel surface of red blood cells that do not swarm to fall to the bottom of the tube. To reduce the errors from the technical result with spinning and shaking. At present, there are companies that produce gel test out the market for at least four companies, but they are very expensive (around 20-23 baht per test) a restriction of the gel test to be applied in their daily work. Therefore, the researchers are seeking to develop and produce more microtube gel test laboratory blood supply. The basic equipment is used in the laboratory. And optimized for the use in various fields, especially in large laboratories to check the reactions of a number of red blood cells. The development by relying on a series of tests in the country. Imports of products with high prices from abroad.
