Hair Follicle Drug Testing - Mcchord Afb, WA

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair offers an extended timeline of alcohol and drug use by capturing biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can provide up to around a 3-month detection period for alcohol and drugs. Hair collection is straightforward, somewhat challenging to tamper with, and easy to transport.

A sample measuring 1.5 inches, consisting of approximately 200 hair strands (equivalent to the size of a #2 pencil) taken closest to the scalp, will yield 100mg of hair, which is the ideal amount for screening and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advisable. Utilize a jeweler’s scale for weighing. In cases where scalp hair is unavailable, an equivalent volume of body hair may be used. References to head hair relate solely to scalp hair, while body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial entry of a sample into the lab’s system, verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and entering any additional data not included in an electronic chain of custody system.

Screening is a preliminary, swift check for drug abuse. While it is a cost-effective means to exclude drug use in most samples, a positive screen requires confirmation for legal admissibility. Any samples testing presumptively positive in Screening necessitate further confirmation.

If a sample tests presumptively positive during Screening, additional hair is extracted from the initial specimen and readied for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than in other methods (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology to conduct.

Confirmation of any positive screening result is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can trace drug use for up to 90 days, unlike urine tests with a more limited detection period.
• Difficult to manipulate: Hair drug tests are challenging to falsify, thus enhancing accuracy.
• Captures usage patterns: It presents a timeline of drug usage over time, beyond recent use.

Limitations:

• Cannot identify recent use: Drugs become detectable in hair within approximately 5-7 days.
• Expense: Hair drug testing is typically pricier than alternative drug testing methods.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentration in hair.

Note: While commonly termed "hair follicle tests", the analysis is conducted on the hair strand, 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.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
