Safariland Abacard Hematrace Test Kits, Pack of 10

The Safariland Abacard Hematrace (Pack of 10) is a test to identify human blood at a crime scene. The kit is stored at room temperature and has a shelf life as long as 20 months. No additional equipment is required. It not only identifies that it is blood but also if it is human, all at the same time. Stains as old as 30 years old have been tested positive with it. Even though a miniscule sample is required, the test is packaged such that the extract can be preserved for years for further analysis. In one of the studies it has also been shown that DNA can be extracted from used cards in case of a need for it.
