Cocaine and Benzoylecgonine Drug Test Kits

Cocaine is a commonly used drug in the UK. It is a nervous system stimulant that can be addictive. Testing urine for recent use of cocaine is achieved by using a benzoylecgonine drug test kit.

Benzoylecgonine Drug Testing Kits

Cocaine itself is only detectable in urine for a number of hours after usage. However, benzoylecgonine, the hydrolytic degradation product of cocaine, can be detected in urine for three to four hours after cocaine has been used. Thus, when testing for cocaine, it is normally benzoylecgonine that it is used as a drug screening test. A cocaine drug test kit is actually a benzoylecgonine drug test kit.

How long after cocaine use can it be detected in the urine?

Benzoylecgonine will take longer to leave the body than cocaine. As stated benzoylecgonine can generally be detected in urine up to 96 hours after use. However, exact clearance rate times of benzoylecgonine from urine can’t be firmly determined. Metabolic rate, weight and certain other factors will all affect the amount go time required for benzoylecgonine to clear the body and for a person to show as being “clear” of cocaine.

Various studies have taken place to see how long it takes for benzoylecgonine to clear the body. Some reports suggest that heavy users may test positive for benzoylecgonine for up to 14 days. Some reports have suggested that this detection period could be as long as 10-22 days using a Benzoylecgonine Drug Test Kit.

Buying Benzoylecgonine Drug Test Kits

Benzoylecgonine drug test kits are available as single drug test kits for cocaine or as part of a multi-drug test kit that can detect cocaine.

False Positive Test Results for Cocaine using a benzoylecgonine drug test kit.

An often heard complaint from some people is that their drug test has come up as positive for cocaine when they have not been using the drug. Certainly this can happen and it is not unheard of for false positive tests to occur. Remember though, it is benzoylecgonine that is being tested for and not cocaine. Benzoylecgonine will show in urine for up to 5 days, or for nearly a month if the usage has been heavy. Benzoylecgonine is the fingerprint metabolite of cocaine that is unique to cocaine.

However, metabolites that are similar in structure to benzoylecgonine may be produced by certain medicines and could produce a ‘positive’ result for cocaine on some tests. Patients with liver or kidney diseases may test differently too and produce a false result when using a benzoylecgonine drug test kit.

What to do if you get a false positive result for Cocaine

A urine drug test for cocaine should be used to provide a preliminary analytical test result. A more specific alternate chemical method should be used in order to obtain a confirmed analytical result. Normally this will be by using a Gas Chromatography/Mass Spectrophotometry (GC/MS) method.

Remember, a careful clinical consideration and professional judgement should be applied when interpreting any positive test when preliminary results are being used from a a benzoylecgonine drug test kit.
