I would like to know under what conditions must blood be stored in order to be able to do DNA tests on the sample and can you do DNA tests on dry blood?

Blood can be stored frozen or dried. Nowadays, instead of using blood, it is much easier to scrape the inside of the mouth with a cotton swab which can then be stored dried or frozen. Often, forensic evidence in the form of dried blood splatter or drops can be successfully analyzed to identify criminals.
