Dried blood stains (dried blood on bandages, on tissue, cotton, or paper)
Dried saliva stains (cigarette butts, stamps, stains on clothing or napkins)
Hair, you will need 6-8 strands per test. (Hair works best if it is taken directly from the head. Hair which has fallen out of the head naturally may work as well. Cut hair will not work, the strands of hair must have roots, that is where the DNA is located)
