Hair Follicle Drug Testing - Key Center, WA

What it is, How it works

Hair testing is viewed as a robust method for identifying drug and alcohol consumption. Hair offers a long-term record of alcohol and drug use by securing biomarkers in the fibers of the hair as it grows. When sourced near the scalp, hair can present up to about a 3-month detection period for both alcohol and drugs. The collection of hair is straightforward, somewhat resistant to tampering, and easy to transport.

A 1.5-inch segment consisting of roughly 200 strands of hair (about the thickness of a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for screening and confirming results. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the sample is advocated. It is suggested to measure the sample on a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair can be used. When referring to head hair, we mean scalp hair specifically. Body hair pertains to all other types of hair (facial, axillary, etc.).

Process Overview

The key phases in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the foundational handling of a sample within a lab’s system. This process comprises verifying that the sample was sealed and shipped correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data input not provided by an electronic chain of custody system.

Screening involves an initial brief assessment for potential drug presence. While Screening serves as a cost-effective method to eliminate drug usage in most samples, a positive result requires confirmation to be valid in legal proceedings. All samples that are tentatively positive in Screening require subsequent confirmation.

If a sample tests tentatively positive during Screening, additional hair is taken from the preliminary sample and readied for Extraction. During Extraction, drugs are obtained from hair at significantly lower concentrations than in other techniques (e.g., urine or oral fluid), which accounts for the complexity of performing hair drug screening.

Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS or LC/MS/MS. All samples with presumed positive results are cleaned before confirmation as necessary. The entire lab procedure from Accessioning to Confirmation is conducted according to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Long detection period: Hair drug tests can identify drug use for a duration of up to 90 days, unlike urine tests which have a shorter detection period.
• Hard to deceive: It is extremely challenging to falsify a hair drug test, resulting in more accurate findings.
• Provides historical insight: It can offer a record of drug use over time, not just recent consumption.

Limitations:

• Cannot detect recent usage: It takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests generally cost more than other methods of drug testing.
• Result variations: Elements like hair color and individual hair growth differences can influence the concentration of drug metabolites in hair.

Note: Though commonly called "hair follicle tests", the testing actually examines the hair strand, 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.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis.
