Lynn Peavey QuickCheck Bloodstain Test Kit, 10 Test

The Lynn Peavey QuickCheck Bloodstain Test Kit contains 10 individual bloodstain tests that can immediately tell you whether or not a substance is blood. Simply moisten a sterile swab with distilled water and rub it across the suspected stain. Break both ampoules, agitate to mix, then drop one or two drops on your swab with the provided applicator. If the sample is blood, the swab will instantly turn a bright blue/green.
