Hemagglutination Inhibition Test
The Hemagglutination Inhibition (HI) Test is a laboratory method used to detect viruses and antibodies in a patient's blood serum, or other body fluids such as saliva or urine. It is a highly sensitive and specific tool for the diagnosis of many infectious diseases, such as influenza, mumps, measles, rubella and influenza. In this test, an antigen is mixed with a specific antibody and if a reaction occurs between the two, a precipitation of the antigen will occur, resulting in a visible “clumping” of particles. This result can be accurately measured to determine the presence of the antigen and the antibody. The HI Test is an essential tool for the diagnosis and treatment of infectious diseases and has applications in clinical and research settings. It is widely used in public health programs and epidemiological surveys to detect infectious diseases, monitor their spread and develop control measures.
