Hair drug testing, alternatively called hair follicle drug testing, represents a scientific approach aimed at identifying drug consumption by examining hair samples.

How it works:

• Drug enters bloodstream: Upon drug usage, the compound and its metabolites (breakdown products) integrate into the bloodstream.
• Drugs reach hair follicles: Due to each hair follicle containing a blood vessel, drugs are transported from the blood to the hair follicle.
• Drugs get trapped in hair: As the hair continues to grow, minute quantities of these chemicals become embedded in the cortex of the hair strand.
• Hair sample collection: A segment of hair is taken, usually from the head (or body hair if there's not enough head hair).
• Lab analysis: The hair sample is dispatched to a lab for examination.
  • Screening: An initial Enzyme-Linked Immunosorbent Assay (ELISA) test is utilized to detect drug metabolites.
  • Confirmation: Should the ELISA test return positive, a more precise confirmation test, such as Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid - Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS), is executed to validate the presence of drug metabolites and eradicate false positives.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can identify drug consumption for up to 90 days, unlike urine tests with a shorter detection period.
• Difficulty to cheat: Cheating a hair drug test is highly challenging, ensuring the results are more precise.
• Provides historical data: It can deliver a timeline of drug use over an interval, not merely recent consumption.

Limitations:

• Cannot detect recent use: Drugs take approximately 5-7 days before becoming detectable in hair.
• Cost: Hair drug tests typically incur higher costs than other drug testing methods.
• Variations in results: Elements like hair color and personal differences in hair growth can impact drug metabolite concentrations in the hair.

Note: Although labeled as "hair follicle tests", the test itself scrutinizes the hair strand and not the scalp's hair follicle.

Extended Detection Window in Illinois
One of the primary benefits of hair follicle drug testing is its extensive detection window. This test can identify drug use over a period of up to 90 days, far surpassing the short timeframe of other testing methods. Employers in Illinois gain a thorough perspective on substance use habits.

By utilizing hair follicle testing, employers can oversee more comprehensive assessments of their workforce's drug history. This longer detection capability supports informed hiring and management decisions, aiding in the fostering of a drug-free environment.

The extended detection window empowers Illinois businesses with tools for sustaining a safe and reliable team. By understanding the substance use habits more fully, employers ensure a higher standard of safety and integrity across operations.

Tamper-Resistant Testing Method in Illinois
Hair follicle drug testing offers significant resistance to tampering, one of its key advantages over other testing methods. The nature of the sample, hair, makes it challenging for subjects to alter or adulterate potential test outcomes.

This resistance is crucial for employers who need accurate results. Since hair samples are collected directly from the donor, tampering attempts like swapping or contaminating samples, commonly associated with other tests, are virtually eliminated.

Employers in Illinois can be assured of the integrity of each result, helping maintain strict adherence to workplace safety policies without question.

Why is Hair Follicle Drug Testing Important

Why Hair Follicle Testing is Superior

• Hair follicle testing detects drug use over a more extended period than URINE tests, offering a comprehensive analysis of usage patterns.
• This method reduces the chance of evasion, as hair samples are nearly impossible to adulterate, ensuring accurate and reliable results.

Reliability and Accuracy

The precision of hair follicle testing surpasses other methods due to its ability to identify drugs long after ingestion, making it ideal for thorough screening protocols.

Comprehensive Detection

While URINE tests may detect recent usage, hair follicle testing excels in uncovering longer-term substance use histories, providing a clearer overview of an individual’s habits.

Adoption in Illinois

Employers across Illinois choose hair follicle testing to enforce effective drug-free workplace policies, backed by the extensive reach and accuracy of this method.
