Hair Follicle Drug Testing - Carriere, MS

What it is, How it works

Hair examination is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and other drugs by encapsulating biomarkers in the strands of the developing hair. When extracted near the scalp, hair can offer up to roughly a 3-month detection timeframe for alcohol and other drugs. Hair is straightforward to gather, somewhat challenging to tamper with, and simple to transport.

A 1.5-inch length sample of around 200 hair strands (roughly equivalent to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for evaluation and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. We suggest weighing the sample on a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be taken. In discussing head hair, we mean scalp hair only. Body hair denotes all other hair kinds (facial, axillary, etc.).

Process Overview

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

Accessioning entails the initial handling of a sample into a laboratory’s system. This comprises confirming that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and performing any extra data entry not offered by an electronic chain of custody system.

Screening comprises an initial rapid assessment for drugs of abuse. While Screening is an economical approach to exclude drug usage on the majority of specimens, a positive screen demands confirmation to be court-admissible. Any samples that are presumptively positive during Screening need a secondary confirmation.

If a sample is presumptively positive during the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are extracted from hair at a significantly lower concentration compared to other methods (e.g., urine or oral fluid), which is why hair drug screening is the most challenging method to execute.

Confirmation of any positive screening outcome is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is audited under both 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 drug tests can uncover drug use for up to 90 days, unlike urine tests that have a shorter detection duration.
• Hard to manipulate: Cheating a hair drug test is highly challenging, boosting result accuracy.
• Offers historical insights: It can depict a trend of drug use over time, rather than just recent consumption.

Limitations:

• Incapable of identifying recent use: It requires about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests typically entail higher costs compared to other drug testing methods.
• Result variations: Aspects like hair color and individual differences in hair growth can influence the concentration of drug metabolites in hair.

Note: Although frequently termed as "hair follicle tests", the test examines the hair strand instead of the hair follicle beneath 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.
