Drug Testing FAQ

Why Do Employers Drug Test?

Alcohol and drug abuse create significant safety and health hazards and can result in decreased productivity and poor employee morale. It can lead to additional costs in the form of health care claims, especially short-term disability claims. Common reasons employers implement drug testing are to:

  • Deter employees from abusing alcohol and drugs
  • Prevent hiring individuals who use illegal drugs
  • Be able to identify drug problems early and appropriately refer employees who have drug and/or alcohol problems
  • Provide a safe workplace for employees
  • Protect the general public and instill consumer confidence that employees are working safely
  • Comply with State laws or Federal regulations
  • Benefit from Workers’ Compensation Premium Discount programs

Why Drug Screening?
Because America’s drug problem is much bigger than most people assume. Read More

When are Drug Tests Conducted?

There are a variety of circumstances for which an organization may require a drug test.

  • Pre-Employment
  • Reasonable Suspicion
  • Post-Accident
  • Random
  • Return-to-Duty
  • Promotion

What is a Chain of Custody?
A chain-of-custody form is used to document the handling and storage of a sample from the time it is collected until the time it is disposed. It links an individual to his or her sample and is written proof of all that happens to the specimen while at the collection site and the laboratory.

What is a Confirmation Test?
A second, confirmation test (by gas chromatography/mass spectrometry or GC/MS) is highly accurate and provides specificity to help rule out any false positives (Non-Negatives) from the initial screen. For a test result to be reported as positive, the initial screen and confirmation test results must agree.

What are the Collection Procedures and Protocol?
We follow strict Department of Transportation Collection Procedures and Protocol and SAMSHA guidelines including:

  • Proper identification of the donor
  • Secure collection facility, minimizing potential for adulteration of specimens
  • Check for possible adulteration of each specimen
  • Completion of Custody and Control forms following Chain of Custody protocol
  • Storage and transportation to SAMSHA confirmatory labs of all Non-Negative & DOT specimens
  • Secure reporting of results to designated employer representative via secure fax or email

What Types of Specimens Does OPTIM LAB TEST Collect?
Non-invasive specimens are collected (Urine and Hair). Urine is the most commonly used specimen for illicit drugs, reflecting SAMHSA’s guidelines.

What Drugs Does OPTIM LAB TEST Test For?

  • AMP Amphetamine
  • BAR Barbiturates
  • BZO Benzodiazepines
  • COC Cocaine
  • m-AMP Methamphetamine
  • MDMA 3,4
  • Methylenedioxy-methamphetamine
  • MTD Methadone
  • OPI2 Opiates
  • PCP Phencyclidine
  • THC Cannabinioids / Marijuana

What is Hair Drug testing?

Hair testing is the most accurate and effective method of finding users of drugs of abuse and can detect drug use for the previous 90 days. Using a small sample of hair cut at the scalp, hair analysis evaluates the number of drug metabolites embedded inside the hair shaft.

How Long are Drugs in One’s System?
Drugs have certain “detection windows”— which is the amount of time after ingestion that evidence of their use can be detected by a drug test.

Unknown substance hair testing

OPTIM LAB TEST can test your hair sample for unknown substance and drugs. An unknown poison and toxin analysis tests for unknown chemicals, poisons, and toxins that include but are not limited to pesticides, organic exposure chemicals, painting or cleaning products, rodent poison, volatiles, and inhalants. This analysis does not test for drugs or heavy metals. No two situations are alike, so contact OPTIM LAB TEST for assistance if you suspect poisoning or toxic exposure.

Difference between Urine and Hair Drug Screen

Many employers find it useful to test both hair and urine for pre-employment purposes. Urine is useful for detecting recent or new drug use (last 1-3 days except Marijuana which is longer) and hair for providing an approximate three-month drug history.

Can Hair testing be beaten?

We have not found any adulterants that can beat the test at this time. Moreover, the risk is minimized because every collection is directly and easily observed. Bleaches, shampoos and external contaminants (i.e. marijuana smoke) have no known impact on test results. Our testing method measures the drug molecules embedded inside the hair shaft, eliminating external contamination as a source of a positive test result. Hair testing results cannot be altered with shampoos or other external chemicals.

How are the hair samples collected?

In order to be fair to the donor, we must have enough hair to repeat assays if necessary. OPTIM LAB TEST may use head, chest, underarm, leg, or facial hair for collection.

Valid and Admissible in Court

OPTIM LAB TEST takes Hair Follicle Test samples under strict Chain of Custody Procedures. The test can include a third Party Medical Review Officer (MRO) verification. OPTIM LAB TEST hair drug test results are court defensible.

Is Anonymous Hair Testing Possible?

Yes, as with many other tests Hair Follicle Testing can be conducted anonymously.

Can hair collected from a brush be used?

Yes, the test will be reported as having an “anonymous” donor.
