Hair Follicle Drug Testing - Keener, NC

What it is, How it works

Hair testing is now regarded as an effective method for identifying drug and alcohol consumption. By embedding biomarkers within the developing hair strands, hair offers a comprehensive timeline of alcohol and drug usage. When gathered near the scalp, hair provides a detection duration of up to around three months for alcohol and other substances. Hair is straightforward to gather, relatively hard to tamper with, and convenient to transport.

A 1.5-inch segment of approximately 200 hair strands (roughly the size of a #2 pencil) nearest to the scalp can yield 100mg of hair, which is the optimal amount for both screening and verification. For EtG, supplementary tests, or analyses exceeding 10 panels, a sample size of 150mg is advised. It is advisable to measure the hair sample's weight using a jeweler’s scale. In cases where scalp hair isn't available, an equivalent quantity of body hair may be opted for. When mentioning head hair, it specifically pertains to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

There are four critical stages in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample into the laboratory’s framework. This phase involves checking whether the sample was correctly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any supplemental data input not supplied by an electronic chain of custody mechanism.

Screening is an initial rapid evaluation for potential drug abuse. While Screening is a cost-efficient method to exclude drug use for most samples, any positive screening must undergo confirmation to be accepted in legal settings. Samples that are initially positive in Screening require further confirmation.

Should a sample show a presumptive positive during the Screening phase, additional hair is retrieved from the original sample for the Extraction phase. In this phase, drugs are removed from hair at a remarkably low concentration compared to other methods (e.g., urine or oral fluid), thus making hair drug testing the most challenging method to administer.

Confirming any presumptive positive screening outcome is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes a wash before confirmation if required. The comprehensive laboratory process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can identify drug usage for up to 90 days, whereas urine evaluations have a shorter detection span.
• Cheating resilience: It is quite challenging to deceive a hair drug test, thus enhancing result accuracy.
• Offers historical insights: Hair drug testing can reveal a usage pattern over a given timeframe, rather than merely recent consumption.

Limitations:

• Lacks recent use detection: It generally takes about 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug testing often involves higher costs compared to other drug testing techniques.
• Result fluctuations: Elements like hair pigmentation and individual hair growth variations can influence the concentration of drug metabolites in hair.

Note: Commonly termed as "hair follicle tests", this test evaluates the hair strand and not the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

In Keener, NC, hair follicle testing stands out due to its superior detection capability compared to standard urine tests. Hair tests are less influenced by recent abstinence and offer a broader historical perspective of substance use.

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.
