Final answer:

The standard test used to determine whether a blood stain is of human or animal origin is the precipitin test. The test works by mixing the blood sample with antiserum specific to human blood and observing if a precipitate forms.

Step-by-step explanation:

The statement is False.

The standard test used to determine whether a blood stain is of human or animal origin is the precipitin test. The precipitin test is a type of immunoassay that detects the presence of specific antigens in the blood. It works by mixing the blood sample with antiserum that is specific to human blood. If a precipitate forms, it indicates that the blood stain is of human origin. If no precipitate forms, it suggests that the blood stain may be of animal origin.

For example, if a blood stain is found at a crime scene, forensic investigators can use the precipitin test to determine if the blood is from a human or an animal source. This information can be important in criminal investigations to help identify potential suspects or rule out certain individuals.
