Drugs of Abuse

Are the rapid drug tests as accurate as GC/MS?

Our drug tests are qualitative, which means it only determines the presence of drugs at detection limits comparable to SAMHSA cut-off concentration. GC/MS, which costs more, quantifies the concentration of drugs in the sample. Given the purposes of most drug testing (pre-employment, post-accident, random) is to detect the presence of drug use and not determine the amounts ingested, our rapid drug test satisfies the needs of almost all Drug Screening Programs.

 

What is the shelf life of the on-site test devices?

Our test devices have a shelf life of 18 months from the date of manufacture. The expiration date of each Lot of devices is indicated on each individual foil pouch and can be used up until that date.

 

Do the results hold up in court?

 

Rapid Drug test provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result- gas chromatography / mass spectrometry (GC/MS) is the preferred confirmatory method. Any result taken to court, must be confirmed.

 

What are the screening cut-off concentrations?

 

The screening cut-off concentrations of our tests are consistent with those of SAMHSA. Those cut-off levels are as follows:

Amphetamines……………....…………………………1000 ng/ml
Barbiturates………………………………………………300 ng/ml
Benzodiazepines…………………......…………………300 ng/ml
Cannabis…………………………...………………………50 ng/ml
Cocaine……………………………………………………300 ng/ml
Methadone…………………………………..……………300 ng/ml
Methamphetamines…………………………...........…1000 ng/ml
Opiates………………………………………..…………2000 ng/ml
PCP…………………………………………………………25 ng/ml
Tricyclic Antidepressants……………............………1000 ng/ml

 

How long do drugs stay in the system?

Amphetamines……………………….….............…2-6 days
Barbiturates………………………............…………3-8 days
Benzodiazepines………………..........……………2-14 days
Cannabis………………………..........……………14-30 days
Cocaine………………………............………………2-5 days
Methadone……………………..............……………2-8 days
Methamphetamines………………...........…………2-6 days
Opiates……………………………............…………2-5 days
PCP…………………………………..........…………3-8 days
Tricyclic Antidepressants………..........……………10 days

 

How accurate are your drug tests?

Laboratory test results for drugs of abuse have indicated a greater than 97% accuracy when used according to the instructions.

 

Is it possible to test positive for THC (marijuana) from exposure to second hand smoke?

Absolutely Not! Urine concentrations of THC above the cut-off sensitivity level of the test, or a positive result, is not possible by exposure to second hand smoke.

 

Will commonly used substances such as vitamins, penicillin, aspirin, caffeine and acetaminophen (Tylenol), affect the results?

No. Our tests are drug and drug metabolite specific. These commonly taken substances are chemically and structurally different after being metabolized by the body from the drugs being tested for and therefore, under most circumstances, not interfere with or compromise test results.

 

Are there any legal medications that can trigger positive results?

Yes. The most common problem is the pseudoephedrine in many over-the-counter sinus and cold medications, which can cause a positive result for methamphetamine. A GC/MS confirmation as well as a MRO review is necessary to determine the source of the positive result. Some forms of the drugs we test for may be available legally under prescription as well.

 

What is the difference between Methamphetamine and Amphetamine?

Both amphetamine and methamphetamine are potent symphathominetic agents. Methamphetamine is the parent drug. It metabolizes into amphetamine in the body. Methamphetamine and/or amphetamine are excreted in the urine.

 

Which category covers Ecstasy?

Methamphetamines.

 

Are Morphine, Opiates, and Heroin the same kind of drug?

Yes, they are all tested using the MOR test. These drugs are from the same family of drugs.
