Hair Follicle Drug Testing - Maggie Valley, NC

What it is, How it works

Utilizing hair testing has become highly regarded as an effective method for identifying drug and alcohol consumption. Hair acts as a record keeper, holding traces of alcohol and drugs within the growing strands. When hair is taken near the scalp, it can offer a detection period spanning up to roughly three months for substances. Collecting hair samples is straightforward, poses challenges to tampering, and is simple to transport.

A 1.5-inch sample comprising around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for analysis and confirmation. For EtG, additional tests, and/or those exceeding 10 panels, it's suggested to obtain 150mg of the sample. Using a jeweler’s scale for measuring the sample is advisable. If scalp hair is not attainable, a similar amount of body hair may be used. The term head hair exclusively refers to scalp hair, while body hair encompasses all other hair forms (facial, axillary, etc.).

Process Overview

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

Accessioning is the phase where the sample is initially processed within a laboratory's system. This process includes confirming the sample was properly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry absent in an electronic chain of custody system.

Screening features a preliminary and swift inspection for drug misuse. While Screening serves as a cost-efficient approach to eliminate drug usage from most samples, a positive finding must be confirmed for it to stand in court. Samples showing presumptive positivity in Screening undergo secondary confirmation.

Should a sample show presumptive positivity in the Screening phase, additional hair is drawn from the primary sample for preparation for Extraction. In this step, drugs are removed from hair at a significantly lower concentration compared to alternative methodologies (such as urine or oral fluid), underscoring why hair drug screening is the most challenging methodology to implement.

GC/MS, GC/MS/MS, or LC/MS/MS perform the confirmation of any positive screening results. Prior to confirmation, all presumptive positive samples undergo cleaning as necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation alongside the ISO / IEC 17025 accreditation standards.

Pros of hair drug testing:

• Extended detection window: Hair drug tests can trace drug use for up to 90 days, while urine tests have a briefer detection span.
• Cheating difficulty: Hair drug tests are exceedingly difficult to manipulate, enhancing result accuracy.
• Supplies historical insights: It presents a timeline of drug usage over an extended duration, not just recent intake.

Drawbacks:

• Incapable of detecting recent usage: It takes nearly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically pricier than alternative drug testing techniques.
• Result variations: Elements such as hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests", the analysis targets the hair strand rather than 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. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.
