Hair Follicle Drug Testing - Walapai, AZ

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting alcohol and drug use. Hair captures long-term substance use history by encasing biomarkers within the fiber of the hair as it grows. When sampled near the scalp, hair provides an approximate 3-month detection timeframe for drugs and alcohol. It is straightforward to gather, challenging to tamper with, and simple to send.

A sample measuring 1.5 inches consisting of around 200 hair strands (similar to a #2 pencil) taken nearest the scalp will yield approximately 100mg of hair, considered the optimal amount for screening and confirmation. For EtG, enhancements, and/or tests exceeding 10 panels, 150mg of the sample is suggested. Utilizing a jeweler's scale for specimen weighing is recommended. In the absence of scalp hair, a comparable amount of body hair may be collected. "Head hair" specifically refers to scalp hair, while "body hair" includes all other varieties (facial, axillary, etc.).

Process Overview

The laboratory processes a drug test result through four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial stage of processing a sample within a laboratory’s system. This process confirms that the sample was properly sealed and shipped, assigns it a unique LAN (Laboratory Accessioning Number), and performs any supplementary data entry omitted by an electronic chain of custody system.

Screening conducts an initial check for common drugs of abuse. Though Screening offers an economical way to dismiss drug use in most cases, a positive screen necessitates confirmation to be valid in legal settings. Samples yielding presumptively positive results in Screening mandate a follow-up confirmation test.

Should the Screening stage yield a presumptive positive, extra hair is extracted from the initial sample for further Examination. In this phase, drug elements are extracted from hair at notably lower concentrations than in other methods (e.g., urine or saliva), which is why conducting hair drug screening is significantly challenging.

Verification of any positive result from screening is achieved via GC/MS, GC/MS/MS or LC/MS/MS. Any presumptive positive samples are washed before verification as necessary. The entire lab sequence from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests for drugs can reveal use for up to 90 days, contrasting with urine tests that have a limited detection timeframe.
• Resistance to tampering: Hair drug tests are notably difficult to manipulate, enhancing the accuracy of results.
• Historical usage data: It offers insights into drug consumption patterns over time, rather than solely recent usage.

Limitations:

• Cannot identify recent drug use: Drugs require approximately 5-7 days to become detectable in hair strands.
• Expense: Generally, hair drug testing incurs higher costs compared to other testing methodologies.
• Result variability: Elements such as hair color and personal hair growth rates can influence the drug metabolite levels in hair.

Note: Though often dubbed as "hair follicle tests", it is the hair strand that is analyzed, not the follicle beneath the scalp

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.
