Uritox Drug Test Everything about Drug Testing Kits

Drug testing reveals information about the presence or absence of certain drugs and/or their metabolites in biological samples like urine, blood, breath, etc., by abusers.  The information is essential nationwide for law enforcement agents, medical service providers, employers, schools, and other institutions to maintain law and order.

 A genuine drug test (though can't assess an individual’s level of ability/inability to do a task sensibly) can provide an accurate reflection of the presence of a drug, metabolites or alcohol within the bloodstream.

 Medical providers, school officials, law officers or employers can draw conclusions of an individual’s abilities to function safely supported by the extent of intoxication.

Advantages of using Saliva Drug Testing Kits over Urine Drug Testing Kits

  1. No Embarrassing Moments

Quite often, it a common for employees to feel shy bladder at workplaces to submit their urine samples.  It is an embarrassing situation for both employer and employee.  In such circumstances, a saliva drug test is the best option, a win-win situation for all.

  1. Tamper-Proof, Adulteration-Proof and Dilution-Proof

Employees tend to tamper with the urine sample by adulterating it with bleach or hydrogen peroxide to test negative.  Some might try to add water to escape the substance detection.  A saliva drug test eliminates the possibilities like tampering, adulterations and dilutions.  Thus, saliva or oral fluid test can be considered 100% genuine.

  1. More Hygienic

Most of the people wouldn't want to deal with a urine sample for genuine reasons like foul smell, infection, leaks, and spills.  Urine tests require careful handling and additional things like protective hand gloves, masks, etc.  The saliva drug test is totally safe, sanitary, and easy to handle.  Just collect the test swab, seal it, and submit for the test.

  1. Immediate Detection Time

Unlike urine drug test that takes longer for the drug to metabolize and excrete from the body (takes several hours), a saliva drug test gives the result instantly after the consumption.  Urine test tends to be inaccurate as it is a time-sensitive specimen.

  1. Can Be Tested Anywhere

Saliva drug test eliminates the necessity of a bathroom or special room at the workplace.  The test can be done anywhere, including open-air or at the very place of accident or at the very instance of suspicious activities.  This test is handy at places like sports venues, construction sites, plantations, mining areas, etc.

None can dispute the accuracy of the urine drug test, its accuracy and cost, but sometimes the test can go wrong with several external elements, so 100% accuracy is not always guaranteed.

What are the drug testing panels?

The term drug testing panels refers to the strips or panels that detect a specific drug in a sample.  A five-panel drug test detects five types of common drugs in a sample, and 12-panel drug test is used to detect 12 types of drugs in the sample.

How does a five-panel drug test work?

Five-panel drug test consists of five strips, which means five substances can be detected using the five-panel test.  The substances are:

  • Amphetamine (methamphetamine, MDA, MDMA, D-amphetamine)
  • Cocaine
  • Opiates (oxycodone, oxymorphone, heroin, codeine, morphine, 6-MAM, hydrocodone)
  • Phencyclidine (PCP)
  • Marijuana (THC, cannabinoids)

Employers may also choose to test for ecstasy, prescription painkillers, anabolic steroids and hallucinogens.
