Storage of saliva and blood specimen in different temperature

In forensic sciences, Blood and saliva are two of the most examined biological samples used in forensic toxicology as they essentially contains all the information (in the form of DNA as well as certain other chemical compounds like salivary amylase etc.) that is needed to narrow down possible suspects and also to determine the identity of the true criminal. There is a time gap between collection of blood from the criminal site and its analysis in laboratory so it is very important to store and handle the biological specimen appropriately in order to maintain its stability. This paper presents a review on storage of biological sample mainly blood and saliva in different temperature.
