What type of drug test do trucking companies use?

The most common drug test administered to truck drivers is the 5 panel drug test. This urine test checks for THC, Opiates, PCP, Cocaine, & Amphetamines.

How accurate is GC MS drug testing?

Only if both portions of the divided specimen show up positive is it considered a positive result by the testing lab. The accuracy of the initial drug screen, the immunoassay test, ranges between 92% – 98%. The accuracy of the GC/MS confirmatory test is virtually 100% from a scientific standpoint.

Do all trucking companies do hair follicle test?

Currently, hair follicle drug testing cannot be used by trucking companies to satisfy Federal DOT drug testing requirements but can be used internally as a prerequisite of employment. The use of hair from elsewhere on the body is normally acceptable if the hair on the head is too short or non-existent.

What can be analyzed with GC MS?

GC/MS can analyze volatile and semi-volatile compounds. Liquid and gas compounds can be analyzed by direct injection into gas chromatography. The samples are vaporized for identification and quantification. Thermal desorption or solvent extraction techniques can be used for solid sample evaluations.

Does Prime Trucking do hair test?

You can also give Recruiting a call to discuss any questions regarding drug testing! As of October 2019 it is urine before you start orientation and hair on day two of orientation. Urine only.

Can you fight a false positive drug test?

The best way to contest false-positive results is to reach out to your pharmacist and ask if prescription drugs and OTC medications you take on a regular basis can cause a positive drug test result. Ask if the pharmacist can provide written documentation to this effect and bring a copy to the test site.

Can GC MS be wrong?

GC-MS is a very specific test to identify separate compounds within a sample. However, GS-MS can also lead to a false negative if the GC-MS column is not designed to identify all potential compounds.

Does Swift do hair follicle test 2020?

Does swift do a hair follicle test for employment? Yes, they do urine and hair test.

What are the disadvantages of GC-MS?

The major disadvantage of using GC-MS for drug confirmation testing or broad spectrum drug screening is that GC-MS methods are not capable of directly analyzing drugs that are nonvolatile, polar, or thermally labile. Derivatization is required to increase the volatility and thermal stability of these compounds.

What is the principle of GC-MS?

The GC works on the principle that a mixture will separate into individual substances when heated. The heated gases are carried through a column with an inert gas (such as helium). As the separated substances emerge from the column opening, they flow into the MS.

What do you need to know about the GC MS Test?

What is GC MS Drug Test? The gc/ms test is a preformed to gather more detailed and specific information on drugs that are detected. It’s a secondary step that confirms any drug metabolites that were detected by the initial screening. If the first test comes up clean, no GC-MS test is done. The cut off levels for a GC/MS Drug Test can be found here.

Is there a way to pass the GC / MS drug test?

The best way to pass any drug test is not to do drugs. But if you find yourself in a situation that is out of your power and will be tested, there’s only one way to pass the GC/MS screening. That’s by not taking it. You must make an effort to pass the initial drug screening and never go as far as taking the confirmation drug test.

What can GC / MS analysis services do for You?

It’s ability to separate, identify, and quantify the individual components of a sample makes it an ideal tool for manufacturers or researchers hoping to identify contaminants, trace elements, strange odors, and more.

Can you get a false positive on a GC / MS Test?

No, the initial urine test, will test for synthetic, fake or diluted urine. If your sample is found to be fake from the initial screening, you fail, no further testing is needed. The GC/MS will “not” produce a false positive. Once the first screening turns up dirty, or with any drug metabolite, its scanned with this method.
