Cocaine(COC) Drug Urine Test is a simple one step test
for the rapid, qualitative detection of COC and primarily benzoylecgonine as metabolites
in urine. The cutoff of the test is 300 ng/ml of COC. It is the same as the SAMHSA
recommended cutoff.
The COC cocaine test provides only a preliminary analytical result. A more
specific alternative chemical method must be used in order to obtain a confirmed
analytical result. Gas chromatography, mass spectrometry (GC/MS) is the preferred
method. Clinical consideration and professional judgment should be applied to
any drug of abuse test result, particularly when preliminary positive results
are used.
EXPLANATION OF THE TEST
Cocaine, derived from the leaves of the coca plant, is a potent central nervous
system stimulant and a local anesthetic. Cocaine induces euphoria, confidence
and a sense of increased energy in the user; these psychological effects are
accompanied by increased heart rate, dilation of the pupils, fever, tremors
and sweating. Cocaine is used by smoking, intravenous, intranasal or oral administration,
and excreted in the urine primarily as benzoylecgonine in a short time. Benzoylecgonine
has a longer biological half-life (5-8 hours) than cocaine (0.5-1.5 hours) and
can generally be detected for 24-80 hours after cocaine use or exposure.
The COC cocaine test is based on the principle of the highly specific immunochemical
reactions between antigens and antibodies, which are used for the analysis of
specific substances in biological fluids. The sensitivity of the test is 300
ng/ml of COC.
