Hair Follicle Drug Testing - Hall, MD

What it is, How it works

Hair analysis has gained recognition as an impactful technique for identifying drug and alcohol consumption. Hair captures a prolonged history of these substances by embedding biomarkers within the hair strand during its growth. When collected close to the scalp, hair offers an approximate 3-month time frame for identifying the presence of drugs and alcohol. The process of collecting hair is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch section consisting of around 200 hair strands (similar in size to a #2 pencil) nearest to the scalp provides 100mg of hair, which is considered the perfect sample for both screening and confirmation. For tests like EtG, add-ons, and those with more than 10 panels, a specimen of 150mg is advised. Using a jeweler’s scale for weighing the specimen is recommended. If scalp hair cannot be obtained, a comparable quantity of body hair can be used. When we mention head hair, we specifically refer to scalp hair. Body hair encompasses all other types of hair (such as facial or axillary hair).

Process Overview

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

Accessioning entails the initial integration of a sample into a laboratory’s system. This step verifies that the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any additional data entry not handled by an electronic chain of custody system.

Screening involves a preliminary assessment for substances of abuse. Though Screening is a cost-effective method to exclude drug use in most samples, a positive screen must be verified for court admissibility. Specimens with presumptive positive results during Screening require a follow-up confirmation.

If a sample exhibits a presumptive positive result at the Screening stage, additional hair is extracted from the original sample and prepared for Extraction. During this stage, drugs are extracted at much lower concentrations than in other methods (such as urine or oral fluid testing), which makes hair drug analysis the most challenging method to execute.

Confirmation of any positive Screening result is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed as required prior to confirmation. The comprehensive laboratory process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair specification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a shorter detection period.
• Challenging to deceive: It is notably difficult to manipulate a hair drug test, ensuring more reliable results.
• Shows historical usage: It can trace a pattern of drug use over a longer duration, not just recent usage.

Limitations:

• Inability to detect recent use: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests typically cost more than other drug testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Although often referred to as "hair follicle tests," the analysis focuses on the hair strand and 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.
