Hair Follicle Drug Testing - Dewy Rose, GA

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. It captures a long-term record of alcohol and drug presence by retaining biomarkers in the hair shaft's fibers. When collected close to the scalp, hair analysis can detect alcohol and drug use for up to roughly a 3-month period. Hair is straightforward to gather, not easily tampered with, and straightforward to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample size for both initial screening and confirmation. For tests like EtG, supplementary examinations, or those exceeding 10 drug panels, a 150mg specimen is advised. Using a jeweler's scale to weigh the sample is recommended. If scalp hair is unavailable, a comparable quantity of body hair can be taken. When we mention head hair, it refers uniquely to scalp hair. Conversely, body hair encompasses all other hair types (such as facial and axillary).

Process Overview

The lab processing of a drug test result includes four main stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary processing of a sample into a laboratory's framework. This step ensures the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any further data input not given by an electronic chain of custody protocol.

Screening serves as an initial rapid assessment for substance abuse. While Screening is a budget-friendly approach for excluding drug use in the majority of samples, a positive result in screening must undergo confirmation to be valid in legal settings. Samples that indicate a presumptive positive during Screening require additional confirmation.

If a sample shows presumptive positivity in the Screening phase, additional hair is obtained from the original specimen and prepared for Extraction. During Extraction, drugs are drawn from hair at much lower concentrations compared to other methods (such as urine or oral fluids), making hair drug analysis a challenging methodology.

Confirming any positive Screening outcome is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair classification and meets ISO/IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for up to 90 days, unlike urine tests, which have a shorter detection span.
• Hard to manipulate: Hair drug tests are particularly challenging to fake, ensuring more reliable results.
• Historical usage data: It can illustrate a history of drug usage over extended periods, not only recent occurrences.

Drawbacks:

• Incapable of identifying recent use: It requires approximately 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug testing generally incurs higher costs than alternative testing techniques.
• Result fluctuations: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Despite often being termed as "hair follicle tests", the examination focuses on the hair shaft and 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. 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.
