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.
- A positive screen for a drug class shows the existence in the system of a substance belonging to that drug class at absorption greater than the standard cut-off.
- Every drug class that shows positive in the drug test commonly is further tested to identify the particular drug or drugs used. Some over-the-counter medicines and legitimately prescribed medications can cause a positive result. Make sure to constantly state any medications you have taken and have treatments for when you have a drug test.
- 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.
- As best option, you can consult a medical expert to help you understand the result of your drug test.
The laboratory can also use blood, saliva, sweat and hair samples for drug testing aside from urine specimen. Drug testing conducted for reasons other than medical purposes follows a firm paper track from the person gathering the sample to the person testing it and discharging results. Most drug testing, commonly screens for the presence of major drugs. Furthermore, particular drugs can be tested if abuse is alleged.
