Heme-Stix
Heme-Stix were developed to provide the investigator with a fast, convenient, sensitive, and reliable presumptive test to identify blood at the crime scene. Each test is a compact, self contained system consisting of two glass ampules inside a plastic tube. These tests are similar to the well known tube tests commonly seen in drug tests. Positive reaction will yield a deep blue color. Contains 10 tests and 10 sampling swabs with instructions.
