serology [sə′räl·ə·jē] (biology) The branch of science dealing with the properties and reactions of blood sera. Serology The division of biological science concerned with antigen-antibody reactions in serum. It properly encompasses any of these reactions, but is often used in a limited sense to denote laboratory diagnostic tests, especially for syphilis. The techniques of blood grouping have come from the study of antigen-antibody reactions in serum, as have techniques for identification of genetic polymorphism and quantitation of numerous serum proteins. With these advances came the means for developing transfusion therapy with cells and plasma. In addition, these techniques led to identification of antibodies involved in incompatibility reactions, such as in erythroblastosis fetalis, and the development of effective measures to prevent their occurrence. Further, extension of these techniques to identification of antigens on white cells led to effective methods of histocompatibility typing, facilitating organ transplantation.

| Alpha recently entered into a laboratory management alliance in which NGI/LabCorp is managing Alpha's serological testing laboratory in Memphis, Tenn. PCR is a nucleic acid testing (NAT) method used to determine the actual presence of infectious agents in the blood, rather than detecting the body's immune response to exposure to disease as is done with serological testing. |
