SIRCHIE® Fingerprint Laboratories introduces the NARK® Progressive System for Drug Identification. NARK® has the capability of presumptively identifying several families of substances suspected of being abused drugs. Designed to function as a transportable narcotics laboratory, it is available for use wherever the need for its capability might arise.
Each of the tests is comprised of one or more chemical reagents. When a predictable color or series of colors occur within a specific testing sequence, a positive confirmation may be presumed. Presumptive identification is generally recognized within our legal system as a component of probable cause.
There is no drug identification system presently in use which completely eliminates the occurrence of false positives and false negatives. A forensic laboratory is required to qualitatively identify an unknown substance.
