Every drug testing professional knows that any preliminary positive urine drug screen must be confirmed by a certified laboratory. A LC/MS/MS confirmation for rapid drug tests is considered to be the "gold standard" in the urine substance abuse testing industry and is nearly 100% accurate. It is our recommendation that you follow these same procedures and send the rapid drug test with preliminary positive result to our laboratory provider for a full confirmation.

 

LC/MS/MS methods to measure test compound levels in all types of fluids and is the quintessential analytical approach to testing for drugs and alcohol. 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. 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!"

 

The primary advantages of this type of test are accuracy and legal defensibility when a Positive Result is obtained in a Onsite Drug Test Kit. The disadvantages are typically costs associated, and the delay in receiving results (up to 4 days.) Each laboratory drug test confirmation is performed on state of the art equipment by experienced staff.
