Laboratory Confirmation - Confirm Positive Drug Test Results
Laboratory confirmation is necessary when an instant drug test kit shows positive results. Lab confirmation will tell exactly what substance was used and can help remove any doubt as to the substance that showed up positive. For example, let us say that someone showed positive for opiates. Lab confirmation will confirm the opiates and a Medical Review Officer (MRO) will call the urine donor to see if they have a prescription for something like Vicodin. With laboratory confirmation, you are able to tell what the person has used and that way they won’t lose their job or violate probation for something that they have been authorized to use, that is, a prescription.
We offer professional laboratory services. Results normally take between 3 and 7days. For information on purchasing top quality lab services at discount pricing, click on one of the links below. Unlike most drug testing companies, we offer not just one, but two methods for drug test positive confirmations. We offer:
GC/MS Laboratory Services (Gas Chromatography Mass Spectrometry – also known as GC/MS or GCMSMS).
LC/MS Laboratory Services (Liquid Chromatography Mass Spectrometry – also known as LC/MS or LCMSMS).
For a GC/MS v. LC/MS comparison, see detailed information below.
Please note that instant drug test kits provide only a preliminary analytical test result. A more specific alternative chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) has been established as the preferred confirmatory method by the National Institute on Drug Abuse (NIDA). Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated. We highly recommend confirming your results with Laboratory Confirmation.

GC/MS/MS v. LC/MS/MS
Which technology is really the "Gold Standard?"
Gas chromatography separates drugs based on how easy they evaporate (volatilize). Unfortunately some substances, such as drugs of abuse, do not volatilize.
However, liquid chromatography separates drugs and introduces them into the mass spectrometer.
The sample first passes through a mass filter which allows only the drugs we are testing for to pass through.
The drug is then broken apart with an argon gas stream. The fragments of any drug present then pass into a second mass filter and are then measured.
No sample pretreatment is necessary, removing one of the problem steps in the GC/MS method.
Only when drugs of abuse are present, are compounds noted by the instrument.
No compound matching is required.
The results are 99.9% accurate.
Liquid chromatography is the true "Gold Standard!"
