How to Understand Drug Tests

Regardless of what type of drug test, it will be hard to interpret or understand the procedure if you don’t have any background yet regarding the screening. A urine specimen is the most usual sample used to identify the presence of drugs. Amphetamines, barbiturates, benzodiazepines, cannibinoids, cocaine, opiates and phencyclidine (PCP) are the seven drug classes that are most normally tested for. Medical practitioners order drug testing on patients showing different signs of substance abuse, primarily to end up on the appropriate treatment. Employers use drug testing predominantly to promote a drug-free workplace. Here’s how to understand drug test:

• Check for your laboratory report for the terms positive or not detected. Every medical laboratory chooses on a cut-off value for each drug class. Any outcome above the established cut-off value is measured as positive, and any value below it is known as negative. In your laboratory record, each drug class confirmed has a positive or not detected result following to it.
  

• Be aware that a “non-detected” result for a drug class doesn’t essentially mean that the person tested did not use illegal drugs previously. The drug or drugs may be current at levels below the recognized cut-off value because they have already been processed and secreted from the body. Amphetamines, cocaine and opiates read positive only if used in the two or three days earlier the specimen collection.
