Long-Term Preservation of Biologicals for the Forensic Laboratory and Their Areas of Application

摘要

The requirement for a wide range of controls in a forensic laboratory testing blood stains, blood crusts, saliva, semen, and whole blood or serum specimens is a unique and problem-posing situation. Controls are absolutely necessary to substantiate results and reagent specificity. Methods of preserving red cells, human bone, semen, and saliva in liquid nitrogen for indefinite periods without deterioration are described. The maintenance of controls and their implementation in a forensic laboratory are presented. The importance of nomenclature in the field of forensic immunohematology is reviewed for workers in this field. (Author)
