Hair Follicle Drug Testing - Harmans, MD

What it is, How it works

Hair testing is recognized as an effective method for identifying drug and alcohol usage. Hair provides a detailed record of alcohol and other substances by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, hair can offer up to a 3-month detection timeframe for alcohol and other substances. Hair is straightforward to collect, less susceptible to tampering, and convenient to transport.

A 1.5-inch segment comprising roughly 200 hair strands (similar to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the ideal quantity for screening and verification. For EtG, additional checks, and/or analyses exceeding 10 panels, 150mg of the specimen is advisable. It is recommended to measure the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair may be collected. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The four primary phases in the laboratory processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the initial handling of a sample within a laboratory’s system. This includes confirming that the sample was correctly sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data entry absent from an electronic chain of custody system.

Screening entails an initial swift evaluation for substances of abuse. Although Screening is a cost-effective method to exclude drug usage in the majority of samples, a positive screen must be verified for court admissibility. Any samples that return a presumptive positive in Screening necessitate subsequent confirmation.

Should a sample yield a presumptive positive during the Screening phase, more hair is extracted from the initial sample for the Extraction process. Here, substances are isolated from hair at a much finer concentration than in other methods (e.g., urine or oral fluid), making hair drug testing a particularly complex method to execute.

Verification of any positive screening outcome is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing prior to confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests have a more limited detection period.
• Challenging to falsify: It is highly challenging to falsify a hair drug test, rendering the results more reliable.
• Offers historical insights: It can reveal a pattern of drug use over time, not solely recent activity.

Limitations:

• Inability to detect recent activity: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variability: Factors like hair color and personal differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Despite being commonly referred to as "hair follicle tests", the test analyzes the hair strand rather than the hair 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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
