Hair Follicle Drug Testing - Lee Center, IL

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. It offers a prolonged overview of alcohol and drugs by embedding biomarkers within the fibers of the maturing hair strand. When gathered near the scalp, hair can offer a detection period of up to about three months for alcohol and drugs. Hair is straightforward to collect, fairly tamper-resistant, and easy to transport.

A 1.5-inch sample of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is perfect for screenings and confirmations. For EtG, additional analyses, or tests exceeding 10 panels, 150mg of the sample is suggested. It's advisable to weigh the specimen using a jeweler’s scale. Should scalp hair be unavailable, a similar quantity of body hair can be obtained. References to head hair pertain solely to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

There are four primary steps in processing a drug test result at the laboratory: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves preliminarily integrating a sample into the lab's protocols. Tasks include verifying proper sealing and shipment of the sample, assigning it a unique LAN (Laboratory Accessioning Number), and finalizing any extra data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary, rapid drug abuse test. Although it's a cost-efficient strategy for excluding drug use in the bulk of samples, a positive finding must be validated to be legally admissible. Presumptively positive Screenings necessitate additional confirmation.

If Screening renders a sample presumptively positive, additional hair is taken from the initial collection and prepped for Extraction. In this phase, drugs are isolated from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), illustrating why hair drug screening is one of the most challenging methods.

Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation if needed. The entire lab process, spanning from Accessioning to Confirmation, is scrutinized under the CAP (College of American Pathologists) Hair designation and the accreditation conforming to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug analyses can identify drug usage for up to 90 days, surpassing the shorter detection span of urine tests.
• Challenging to manipulate: Altering a hair drug test is notably difficult, granting more precise results.
• Reveals historical trends: It depicts a pattern of drug consumption over a timeframe rather than sole recent usage.

Limitations:

• Can't detect immediate use: Drugs typically become observable in hair after 5-7 days.
• Expense: Generally, hair drug tests cost more than other testing methods.
• Result variability: Elements like hair color and personal hair growth differences can influence drug metabolite concentrations in hair.

Note: Although often termed "hair follicle tests", the analysis actually examines the hair strand, not the follicle under the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
