Detect the peroxide-like activity of hemoglobin in a substance with these convenient test sticks. This material, commonly used at crime scenes, determines if the evidence seen is actually blood spatter, before any lab analysis is conducted. Simply apply a small amount of distilled water to the Hemastix, then rub the stick on a sample and compare the results to the chart on the bottle. If the reaction is positive, the blood sample can be collected as evidence.
