Urine Drug Testing
July 6, 2010 in Employee Drug Testing Information
The detection times in urine are significantly greater than detection times in blood, which is also generally much more expensive. The presence of a drug or drugs in urine does not provide information as to whether the individual is actually under the influence at any particular time. Likewise, no determination can be made from urine as to the amount of the dose or the time of the dose.
Blood testing, on the other hand may provide more suitable information about whether or not an individual is “under the influence”, though this may not be conclusive in all cases.
Urine drug testing accuracy is variable depending on how the testing is done. Drug testing is extremely accurate and reliable when all aspects of the testing process are done properly. On the other hand, the information obtained may be very misleading and inaccurate when poor procedures or testing methods are utilized. Drug testing will only be reliable when the consumer knows how it should be done and then demands from the industry that it is done properly.
