Forensic scientists use these acid phosphatase tests in the field and in laboratories.

Gunshot Residue Test
Investigators use these BlueClue tests in the field to detect the nitrates found in gunpowder for instant presumptive results.
- Place the collected sample in the bag and close it.
- After several seconds, if small blue specks appear, you have a positive presumptive result for the nitrates in gunpowder.

- The Forenstix test is a self-contained packet consisting of two glass ampules inside a plastic tube. A positive presumptive reaction to blood will yield a deep blue color.
