What is a presumtive test?
In medicine and forensics there are many tests considered "presumtive". Presumptive means that the test provides enough indication of a substance, but without the full testing needed to verify, scientifically, that the substance is present. Probably one of the best known forensic presumptive tests is the one that tests for the presence of blood. Forensic workers can see a "red spot of fluid" on the floor, a take a swab. The swab is either coated with a chemical, or the swab is inserted into a container containing a chemical that will turn the fluid a certain color if the fluid is blood. But, the presumptive test is not considered fact until further testing in a lab shows that yes, the fluid was indeed blood. I believe that law enforcement can also run presumptive tests in the field when they suspect a substance is a street drug. Normally, if the presumtive test changes colors, the suspected substance is also tested in the lab. In courts, the lab tests give the evidence, not only the presumtive field testing (for both crime scenes and drug arrests).
