The determination of whether or not a substance is blood is best made by means of a preliminary color test such as the Kastle-Meyer color test, which uses the chemical: 

• precipitin. 
• phenolphthalein. 
• p30. 
• benzidine.

This test forms characteristic crystals containing hemoglobin when specific chemicals are added.

• Luminol

• microcrystalline test

• Kastle-Meyer test

• Gel Diffusion

To test whether or not a blood sample is of human or animal origin, the standard test that is used is..

• p30
• Radioimmunoassay
• Kastle-Meyer
• Precipitin
