ABSTRACT

In Forensic Science Laboratories, so many cases are received under various crime heads. In Biology Division, cases are received under IPC.302 307,323,363,366,376,377,498 etc. All cases are Medico-legal cases. In these cases, blood samples are major constituents for detection of blood groups. But unfortunately, some of these samples get haemolysed due to various reasons. Haemolysed samples are rather frequent occurrence in forensic science laboratories. In most of the cases, blood samples get haemolysed due to preanalytical sources related to incorrect procedures or failures to follow procedures for collection, handling, storage of the samples and delay for the examination. Since, haemolysed samples are often an important cause of inconclusive blood grouping; also it hampers the success rate of conviction. The objective of this study is to discuss the cause of haemolysis and success rate of the biological analysis.
