Agglutination reaction. Agglutination refers to a clumping that occurs when an antigen comes into contact with its corresponding antibody. This process mimics what happens in the body when antibodies cause antigens to agglutinate, promoting easy removal of the infectious organism.
Cytopathology is a branch of pathology involving the study and diagnosis of diseases at the cellular level using a light microscope. Traditionally the discipline has been divided into cervical cytopathology (commonly referred to as cervical cytology) and diagnostic cytopathology. Diagnostic cytology is mainly used for diagnosis of cancer in many parts of the body.
Neuropathology is the study of disease of nervous system tissue, usually in the form of either small surgical biopsies or whole-body autopsies. Neuropathologists usually work in a department of anatomic pathology, but work closely with the clinical disciplines of neurology, and neurosurgery, which often depend on neuropathology for a diagnosis. Neuropathology also relates to forensic pathology because brain disease or brain injury can be related to cause of death. Neuropathology should not be co
