Hair Follicle Drug Testing - Sweet Air, MD

What it is, How it works

Hair analysis has gained recognition as a potent instrument for identifying substance and alcohol use. Hair records a prolonged history of alcohol and drugs through the entrapment of biomarkers within the fibers of the developing hair strand. When trimmed close to the scalp, it can reveal up to an estimated 3-month detection period for substances and alcohol. Hair is straightforward to collect, relatively challenging to tamper with, and simple to transport.

A 1.5-inch segment of roughly 200 hair strands (analogous in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for testing and verification. For EtG, additional tests, and/or tests exceeding 10 panels, it is advised to collect 150mg of the specimen. A jeweler’s scale is recommended for specimen weighing. If scalp hair is not present, a comparable amount of body hair may be gathered. References to head hair pertain exclusively to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning encompasses the preliminary processing of a sample into a lab’s system. This step verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry not included via an electronic chain of custody system.

Screening involves a preliminary rapid assessment for drugs of abuse. Although Screening is a cost-efficient means for ruling out drug use in most samples, a positive screen must be confirmed for court admissibility. Any samples deemed presumptively positive in Screening necessitate secondary confirmation.

Presumptive positive samples during Screening have additional hair extracted from the original specimen for the Extraction phase. Here, drugs are extracted from hair at concentrations much lower compared to other methods (e.g., urine or oral fluid), rendering hair drug screening the most challenging method to carry out.

Positive screening results are confirmed using GC/MS, GC/MS/MS or LC/MS/MS. Presumptively positive samples are washed before confirmation if necessary. The laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug analyses can reveal drug use for durations up to 90 days, unlike urine tests which have briefer detection periods.
• Hard to falsify: The hair drug test's resistance to manipulation enhances result accuracy.
• Reveals historical data: It can outline a pattern of drug usage over time, beyond just recent use.

Limitations:

• Incapable of detecting recent use: Drugs become detectable in hair approximately 5-7 days after usage.
• Expense: Hair drug analyses generally incur higher costs than alternate testing approaches.
• Result variations: Factors including hair color and individual hair growth differences can impact drug metabolite concentrations in hair.

Note: Despite often being termed "hair follicle tests", the analysis is performed on the hair strand and not the subdermal hair follicle

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.
