Hair Follicle Drug Testing - Capulin, NM

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol use. Hair captures a long-term record of alcohol and other substances by embedding biomarkers within the fibers of the growing hair. When hair is collected near the scalp, it allows for a detection period of up to about three months for alcohol and drugs. Hair is easy to gather, hard to tamper with, and convenient to transport.

A 1.5-inch sample of roughly 200 hair strands (comparable to a #2 pencil) near the scalp provides 100mg of hair, which is the optimal amount for initial screening and confirmation. For EtG, additional tests, and/or panels beyond 10, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair can be used. By head hair, we mean specifically the scalp hair. Body hair includes all other hair types (like facial, axillary, etc.).

Process Overview

The major steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, a sample is initially entered into the lab's system. This step involves checking that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any other data entry not covered by an electronic chain of custody system.

Screening provides an initial assessment for substances of abuse. While Screening is a cost-effective method to eliminate drug usage for most samples, a positive screen must be validated to be permissible in court. Samples that show a presumptive positive in Screening necessitate a secondary confirmation.

If Screening indicates a presumptive positive, additional hair is extracted from the original sample for the Extraction stage. In this phase, drugs are taken from hair at much lower concentrations than with other methods (e.g., urine or oral fluid), which makes hair drug screening particularly challenging.

Confirmation of any positive result from screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as necessary. The full lab process from Accessioning through Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests can reveal drug use for up to 90 days, in contrast to urine tests with shorter detection periods.
• Difficulty to cheat: Cheating on a hair drug test is quite challenging, which increases result accuracy.
• Provides historical data: It can show a pattern of drug use over time rather than just recent use.

Limitations:

• Cannot detect recent use: It generally takes about 5-7 days for substances to be detectable in hair.
• Cost: Hair drug tests typically cost more than other drug testing methods.
• Variations in results: Variables like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often called "hair follicle tests," this test actually analyzes the hair strand 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.
