Hair Follicle Drug Testing - Holstein, IA

What it is, How it works

Hair testing has emerged as an effective method for identifying drug and alcohol use. By encasing biomarkers within the growing hair strand, hair provides a historical record of alcohol and drug consumption over time. Collected near the scalp, hair can offer a detection timeframe of up to roughly 90 days for alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and can be efficiently transported.

A 1.5-inch hair sample with approximately 200 strands (comparable to a #2 pencil's thickness) near the scalp yields about 100mg, the optimal sample size for screening and confirmation. For EtG, additional testing, or tests requiring more than 10 panels, 150mg of the sample is advised. The specimen should be weighed using a jeweler’s scale. If scalp hair is missing, an equivalent amount of body hair can be taken. "Head hair" denotes only scalp hair, whereas "body hair" includes all other types (e.g., facial, axillary).

Process Overview

The primary steps in the lab processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary processing of a sample within a laboratory's system. This stage ensures the sample was sealed and shipped correctly, assigns it a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.

Screening performs an initial rapid assessment for drugs of abuse. While Screening cost-effectively eliminates drug use for most samples, a positive result must be confirmed for legal admissibility. Samples with presumptive positive results in Screening need further confirmation.

If Screening yields a presumptive positive, additional hair is taken from the initial specimen for Extraction. This stage involves extracting drugs from hair at much lower concentrations than other methods, such as urine or oral fluid, making hair drug screening 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 presumptively positive samples are cleansed before confirmation when necessary. The complete laboratory process from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair designation and is certified to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug use for up to 90 days, unlike urine tests with shorter detection times.
• Resistant to tampering: It's exceedingly difficult to manipulate hair drug test results, ensuring greater accuracy.
• Offers historical insights: It provides a timeline of drug use over months, not just recent consumption.

Limitations:

• Cannot identify recent usage: Detection in hair takes roughly 5-7 days for drugs.
• Expense: Hair drug testing often costs more than alternative methods.
• Result variability: Hair color and personal hair growth variations can influence the concentration of drug metabolites in hair.

Note: Often called "hair follicle tests", these tests examine the hair strand itself, 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.
