Answer:

A precipitin test is used to distinguish between animal and human blood. The test involves an antiserum that interacts with the blood. Human blood will interact with the serum to form a cloudy ring between the blood and the serum. The precipitin test requires a very small amount of blood and is useful for up to 10 to 15 years on dried blood.
