Hair Follicle Drug Testing - Crellin, MD

What it is, How it works

Hair analysis is recognized as a potent method for identifying drug and alcohol usage. Hair captures a comprehensive timeline of substance intake by encasing biomarkers in the hair shaft. When trimmed close to the scalp, hair can provide a detection timeframe of up to roughly three months for drugs and alcohol. Collecting hair is straightforward, relatively resistant to tampering, and convenient for transport.

An optimal specimen for testing and verification is a 1.5-inch segment of roughly 200 hairs (comparable to the diameter of a #2 pencil) nearest the scalp, yielding approximately 100mg of hair. For EtG, supplementary tests, and/or more than 10-panel screenings, a 150mg sample is advised. We suggest using a jeweler’s scale to weigh the sample. If scalp hair cannot be obtained, an equivalent quantity of body hair can be used. References to head hair pertain exclusively to scalp hair, while body hair encompasses other types (facial, axillary, etc.).

Process Summary

The four primary phases in the lab analysis of a drug examination are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial integration of a specimen into a lab’s database, ensuring the sample’s secure sealing and transport, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data input not managed by an electronic custody chain system.

Screening acts as an initial rapid assessment for substance abuse. Although it serves as a cost-efficient method to exclude drug use in most cases, a positive screen mandates further validation to be valid in legal settings. Samples with presumptive positive results in Screening necessitate secondary confirmation.

If Screening yields a presumptive positive result, additional hair is taken from the original sample and prepped for Extraction. In this phase, substances are isolated from hair at lower concentrations than alternative techniques (e.g., urine or oral fluids), making hair drug screening the most complex testing method.

Positive Screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed prior to confirmation as required. The complete lab procedure from Accessioning to Confirmation undergoes scrutiny under both CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Benefits of hair drug analysis:

• Extensive detection period: Hair drug assessments can reveal drug consumption up to 90 days prior, unlike urine tests with shorter detection spans.
• Hard to deceive: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
• Shows usage trends: It illustrates drug use patterns over time, not just recent intake.

Drawbacks:

• No recent usage detection: It typically requires 5-7 days for substances to become noticeable in hair.
• Expense: Generally speaking, hair drug tests are costlier than alternative testing methods.
• Result variability: Factors like hair color and personal hair growth differences can impact drug metabolite concentrations in the hair.

Note: Often termed "hair follicle tests", this assessment examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In the realm of drug detection, hair follicle testing in Crellin, MD, sets the bar higher than traditional urine testing. Hair tests offer unparalleled detection accuracy and reliability, capturing drug use history that urine tests often miss. This makes them indispensable for employers maintaining a zero-tolerance policy.

Unlike urine tests, hair follicle testing provides a detailed account of past substance use, essential for thorough employee vetting. This superior efficacy helps maintain a safe work environment and supports fair hiring practices across industries.

Extended Detection Window
