Hair drug testing, or hair follicle drug testing, applies a scientific approach to identify drug usage by examining hair specimens.

How it works:

• Drug enters bloodstream: When drugs are used, the substance and its metabolites (breakdown byproducts) infiltrate the bloodstream.
• Drugs reach hair follicles: As each hair follicle is supplied by a blood vessel, drugs move from the blood into the hair follicle.
• Drugs get trapped in hair: These trace chemical amounts embed into the hair strand's cortex as it grows.
• Hair sample collection: Typically, hair is taken from the head (or body hair if head hair is lacking).
• Lab analysis: The collected hair sample is dispatched to a lab for analysis.
  • Screening: An Enzyme-Linked Immunosorbent Assay (ELISA) test is initially performed to detect drug metabolites.
  • Confirmation: Should ELISA results be positive, a more refined confirmation test, like Gas Chromatography-Mass Spectrometry (GC/MS) or Liquid Chromatography-Mass Spectrometry/Mass Spectrometry (LC/MS/MS), is executed to verify the presence of drug metabolites and eliminate false positives.

Advantages of hair drug testing:

• Long detection window: Detects drug use up to 90 days, whereas urine tests have a smaller detection timespan.
• Difficulty to cheat: Hair drug tests are notably hard to falsify, adding to their accuracy.
• Provides historical data: It reflects a pattern of drug use over time, beyond recent activity.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair only after roughly 5-7 days.
• Cost: Hair drug tests typically incur higher costs than other testing methods.
• Variations in results: Hair color and individual hair growth variations can influence drug metabolites' concentrations in the hair.

Note: Commonly termed "hair follicle tests", the procedure examines the hair strand, not the scalp's underlying hair follicle.

The precision of our hair follicle tests ensures confidence in the RESULTS. Employers can trust the data to inform decisions, knowing that our state-of-the-art labs utilize advanced technology to deliver only the highest quality analysis.

Hair follicle testing offers an extended DETECTION window, making it an exceptional choice for monitoring long-term drug use. With a capability of detecting drug intake up to 90 days prior, it provides a holistic view of an individual's substance usage history.

This long-range DETECTION period is crucial for employers who wish to assess patterns, not just instances, of substance use, thereby making more thorough and informed hiring decisions based on comprehensive data.

One significant advantage of hair follicle tests is their TAMPER-resistant nature. Unlike other methods, hair samples are less susceptible to adulteration or substitution, providing a more secure form of testing for accurate and genuine results.

By minimizing the chances of TAMPER attempts, these tests safeguard the integrity of the analysis, ensuring that employers can rely on the outcomes without the risk of false negatives or misleading evidence.

Why is Hair Follicle Drug Testing Important

When comparing hair follicle testing to other methods like URINE testing in Vermont, the advantages are clear. Hair follicle tests boast a longer detection period, capturing substance use over a more extended timeframe, typically up to 90 days. This widens the window of insight significantly over URINE testing’s limited detection period.

Superior Accuracy: Hair tests minimize chances of contamination and false positives, offering employers a higher level of confidence in results. Unlike URINE, hair follicles capture metabolites within the shaft, providing a precise history that's hard to contest.

Enhanced Reliability: In contrast to URINE, hair samples are less likely to be tampered with since they are collected under secure conditions and without the need for immediate processing. This ensures stability and integrity of the sample.

• Long-lasting Detection: Unlike URINE, which is best for recent substance use, hair testing allows for a comprehensive overview.
• More Substances Detected: With hair follicle testing, a broader spectrum of substances can often be detected.
• Non-Invasive Collection: A quick sample cut is less intrusive than a URINE collection, enhancing employee comfort during the process.
