Hair Follicle Drug Testing - Proctorsville, VT

What it is, How it works

Hair tests have become recognized as an effective method for identifying substance and alcohol consumption. Hair captures a long-term record of alcohol and drug usage by embedding biomarkers in the fibers of the growing strand. When cut near the scalp, hair can offer up to an approximate 3-month window for detecting alcohol and drugs. Hair is easy to obtain, relatively resistant to tampering, and straightforward to transport.

A sample of 1.5 inches of about 200 strands of hair (around the dimension of a #2 pencil) taken nearest the scalp equates to 100mg, which is the optimal sample size for testing and validation. For EtG, additional screenings, or tests exceeding 10 panels, a 150mg quantity is advised. We suggest measuring the sample using a jeweler’s scale. If there is no scalp hair, a similar quantity of body hair may be used. When mentioning head hair, we mean scalp hair specifically. Body hair includes other types of hair (facial, axillary, etc.).

Process Overview

The principal stages in the lab processing of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary intake of a sample into a lab's system. This process includes ensuring the sample was properly sealed and transported, assigning an arbitrary LAN (Laboratory Accessioning Number), and completing any necessary data entry not supplied by an electronic custody chain system.

Screening is an initial rapid assessment for substance abuse. While Screening is an economic method to exclude drug use in most samples, a positive screen necessitates confirmation to be legally acceptable. Samples that are initially positive in Screening need a secondary confirmation.

Should a sample show a presumptive positive in the Screening stage, additional hair is retrieved from the initial sample and readied for Extraction. Drugs are drawn out from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), which is why hair drug testing is considered one of the most complex methodologies.

Positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples undergo washing before confirmation as necessary. The full lab procedure from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can trace drug usage for up to 90 days, in contrast to urine tests that have a shorter detection period.
• Challenging to manipulate: Hair drug tests are hard to cheat, leading to more precise results.
• Offers historical insight: It can outline a timeline of drug use over an extended period, beyond just recent usage.

Limitations:

• Cannot identify recent consumption: Drugs take approximately 5-7 days to be observable in hair.
• Expense: Hair drug tests typically cost more than other drug testing techniques.
• Result variations: Elements like hair color and personal differences in hair growth can influence the drug metabolite concentration in hair.

Note: Commonly termed as "hair follicle tests", the test itself 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. 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.
