Resumo: | Blood is the only fluid tissue present in the human body, consisting of red blood cells, leukocytes and platelets, being responsible for 7 to 8% of total body weight. This connective tissue performs numerous functions and, being easily accessible through venipuncture, it’s used to study the physiological mechanisms of the organism. In crime scenes, blood is considered one of the vestiges of great expert interest to elucidate the case. When not apparent, luminol is used, a substance that, when in contact with H2O2, O2, ClO-, and catalysts such as, for example, the blood itself and the Fe + 2 ion present in the heme portion of hemoglobin, presents a reaction which emits visible light through electromagnetic radiation, called chemiluminescence. However, there’re many other compounds that can activate this reaction, significantly interfering in the search for information that leads to the clarification of a crime. Therefore, the present study aims to carry out a bibliographic review on the possible interferences in the study of human blood, with the objective of assisting the research of latent blood in crime scenes. |
