Hair Follicle Drug Testing - Seboyeta, NM

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug presence by embedding biomarkers within the fibers of the hair as it grows. When taken from near the scalp, hair can offer a detection period of up to about three months for alcohol and drugs. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch hair sample consisting of roughly 200 strands (approximately the girth of a #2 pencil) nearest to the scalp provides 100mg of hair, which serves as the optimal quantity for screening and confirmation. For EtG, supplementary tests, and/or panels exceeding 10, a specimen amount of 150mg is advisable. It is suggested to weigh the specimen on a jeweler’s scale. If scalp hair is unavailable, an equivalent volume of body hair can be collected. When mentioning head hair, it pertains solely to scalp hair. Body hair encompasses all other hair varieties (facial, axillary, etc.).

Process Overview

The processing of a drug test in a lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning refers to the initial integration of a sample into the lab's system. This involves confirming the proper sealing and shipping of the sample, allocating a random LAN (Laboratory Accessioning Number), and completing any additional data input absent in an electronic chain of custody system.

Screening is an initial brief assessment for drugs of abuse. Although Screening is an economical method for eliminating drug usage in most samples, a positive result requires confirmation to be legal in court. Samples showing presumptive positivity in Screening necessitate a secondary confirmation.

Should a sample show presumptive positivity in Screening, additional hair is taken from the initial sample for Extraction. In this phase, drugs are extracted from hair at notably lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring why hair drug screening is among the most challenging methodologies.

Any positive screening outcome is confirmed via technologies such as GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing before confirmation if required. The entire laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug tests detect drug usage up to 90 days, in contrast to urine tests that have a shorter detection period.
• Testing integrity: Cheating a hair drug test is extraordinarily difficult, ensuring more reliable results.
• Historical usage data: It reveals usage patterns over a timeline, not merely recent consumption.

Limitations:

• Inability to detect recent consumption: Drugs take approximately 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically costlier than alternative drug testing techniques.
• Result variations: Elements like hair color and individual hair growth variations can influence the concentration of drug metabolites in hair.

Note: Although frequently called "hair follicle tests", the evaluation targets the hair strand, not the follicle located 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.
