There is a tremendous difference between the Kacey Nicotine tests and standard common human Nicotine tests. Standard Nicotine Human tests have a much higher LOD (level of detection) for human levels of detection then that of the Kacey Nicotine test for animals.
The Kacey Veti-Screen Nicotine test was developed for animals and not humans therefore, the Kacey Nicotine tests should never be used to determine Nicotine values in humans. However, the Kacey DOA tests have a lower LOD which detects clinical levels which would otherwise appear as a “False Negative” in human tests.
