Detailed explanation-1: -A presumptive test is a chemical test which, by production of color or light, indicates the presence of a body fluid. It is typically more sensitive and less specific than a confirmatory test. A confirmatory test is a test that verifies the presence of a specific compound.

Detailed explanation-2: -Confirmatory Tests: Infrared Spectroscopy (IR)1-A spectrum is obtained by passing infrared radiation through a sample and determining the amount of the incident radiation (radiation that actually hits the molecule rather than passing through) that is absorbed at each IR frequency.

Detailed explanation-3: -There are two main types of tests used to determine whether an illegal drug is present in a substance: presumptive tests and confirmatory tests. Presumptive tests are less precise and indicate that an illegal substance may be present. Confirmatory tests provide a positive identification of the substance in question.
