“Cut-off level” refers to the point within which a drug test is called negative and above which a drug test is called positive.  For drug screening, the cut-off mark is an essential criterion for judgment.  It should be noted that a negative result does not mean that a sample is drug-free but may contain the amount of drug that is below the cut-off level.

Common substances that tend to turn the result positive

  • Antidepressants

Apart from the Drug, What else can be Tested with the Drug Testing Kits?

For certain types of ailments, the physician might ask the patients to do a urine test to detect specific contaminants.  Some urine drug test kits are also used to detect common adulterants.  People who cannot move or travel due to disability, impairments, obesity, age, sickness, etc., can use the drug testing kits and verify with their physicians regarding the results.  Detecting common adulterants would be highly useful in such cases.

The common adulterants that can be detected are

  • Urine pH – The pH value determines the acidic or base nature of the urine sample.
  • Specific gravity – This value indicates more solids or more water in the urine sample.
  • Color – Certain medical conditions like diet, diseases, medicines influence the color of the urine sample.
  • Nitrites – The presence of this substance indicates a bacterial infection.
  • Odor – Foul odor indicates blood, pus, or bacterial infection.
  • Oxidants – The presence of oxidants.
  • Creatinine – Creatinine level indicates the amount of waste in the specimen.
  • Glucose – Detects glucose level in the blood.

What Adulterants are Used by Tricksters to Render the Drug Test Invalid?

PCC, popularly known as 'Urine Luck,’ may be used by the candidates to tamper with the drug test.  This chemical affects the pH of urine and shields drug metabolites in the urine sample.

Another adulterant called Glutaraldehyde restricts the enzyme used to detect drugs in urine thereby turning the result “invalid.”

Can you Drink Water Before a Urine Test?

Before the test, one should drink as much water as possible to get an adequate urine sample.  However, sometimes drinking excessive amounts of water may cause inaccuracy in results.  One can include milk and fruit juices in combination with water for better results.

Drinking a little amount of coffee or tea an hour before the test has a minor diuretic effect and will not wholly dilute the sample.

Can Ibuprofen Cause You to Fail a Drug Test?

Ibuprofen is one of the main culprits in influencing the test result.  Research studies show that most of the people taking high doses (above 800 mg per day) tested positive for THC (cannabinoids), PCP, and barbiturates.

Does Peeing Remove Toxins From the Body?

Unfortunately, taking more water than the required amount will not flush the toxins out of the system, nor will it help the excretory system (kidneys).  The only change will be the change in color of the urine, i.e., yellow to clear.  According to some research studies, consuming a large amount of water (around one gallon) before the test dilutes the metabolites in urine and renders the urine drugs undetectable.

Is a 12 Days Period Enough to Pass a Drug Test?

The easiest and most natural way to pass a drug test is to stop consuming cannabis.  For a small number of cannabis users, stopping consumption at least ten days before the test should be enough.  For heavier users, it is recommended for at least a minimum of one month.

  • A rare user (less than two times per week) can test positive for 1-3 days.
  • A frequent user (several times per week) can test positive for 7-21 days after the last use.
  • A heavy user can test positive for 30 days or even more after last use.

Reasons the Employers Do the Drug Test

Non-DOT complainant employers usually do drug testing or screening of their employees at the workplace itself.  Employees who test non-negative are directed to visit the confirmatory test.  Employers go for drug testing primarily for the following reasons:

  • Pre-employment test
  • Random drug test
  • Test on return to duty
  • Post-accident drug test
  • Scheduled drug test
  • Follow-up drug testing
  • Drug testing on reasonable suspicion

Drug Testing Categories

Broadly speaking, there are three ways of drug testing for individuals and employers.

  • Instant drug testing
  • Same-day-result drug testing
  • Drug testing by labs

The factors that influence drug testing are drug testing purpose, cost, accuracy, and time.

Types of Drug Tests

There are six types of drug tests.  Individuals and employers can choose any one or a combination of three, depending on the requirements, compliance, and time factor.

  • Breath alcohol test (for instant result)
  • Urine drug test
  • Blood drug test
  • Hair drug test
  • Saliva or oral swab drug screening
  • Sweat drug screening

What Type of Drug Testing Can be Done with Drug Testing Kits?

Blood sweat and hair drug testing can be done only in the lab because these tests require expertise and knowledge. Urine and saliva drug tests can be done with drug testing kits.

What are the primary advantages of drug testing kits?

  • Drug testing kits are comparatively cheaper than lab-based tests.
  • Tests can be administered by non-professional (but instructions supplied with the kits should be strictly adhered to).
  • Drug testing kits can be used anywhere and anytime.
  • More than 20 types of drugs can be detected with drug testing kits.
  • Simple and easy procedure.
  • Available over-the-counter at nearby pharmacies and stores.

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

1. No Embarrassing Moments

It is often common for employees to feel a 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.

2. 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 tests can be considered 100% genuine.

3. More Hygienic

Most 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 other things like protective hand gloves, masks, etc.  The saliva drug test is safe, sanitary, and easy to handle.  Just collect the test swab, seal it, and submit it for the test.

4. Immediate Detection Time

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

5. Can Be Tested Anywhere

Saliva drug test eliminates the necessity of a bathroom or particular room at the workplace.  The test can be done anywhere, including open-air or at the very place of accident, or the same 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. Still, 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 a 12-panel drug test is used to detect 12 types of drugs in the sample.

How does a Five-Panel Drug Test Work?

A 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, 6-MAM, codeine, morphine, 6-MAM, hydrocodone)
  • Phencyclidine (PCP)
  • MMJ (THC, cannabinoids)

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