Hair Follicle Drug Testing - Dragoon, AZ

What it is, How it works

Hair testing has progressively gained recognition as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of an actively growing hair strand, hair offers a long-lasting account of alcohol and drug use. When procured near the scalp, hair can reveal up to roughly a 3-month detection period for alcohol and drugs. Hair samples are easy to gather, challenging to tamper with, and effortless to transport.

A sample measuring 1.5 inches consisting of around 200 hair strands (similar in breadth to a #2 pencil) taken nearest to the scalp will yield 100mg of hair, which is the ideal sample size for evaluation and verification. It is advised to collect 150mg of the specimen for EtG, add-ons, and/or tests exceeding 10 panels. Using a jeweler's scale to weigh the specimen is recommended. If scalp hair is inaccessible, a similar quantity of body hair may be used. When referring to head hair, it specifically denotes scalp hair. Conversely, body hair pertains to all other types such as facial, axillary hair, etc.

Process Overview

The drug test result processing in the laboratory comprises four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial processing of a sample into a laboratory's framework. This phase ensures the sample's proper sealing and shipping, assigns a unique LAN (Laboratory Accessioning Number), and any remaining data input not included by an electronic chain of custody system is completed.

Screening contains an initial swift examination for substance abuse. Although Screening offers a cost-efficient method to rule out drug use in most samples, a positive screening must undergo confirmation for legal admissibility. Samples that are presumptively positive in Screening necessitate a confirmatory test.

If a sample presents a presumptive positive at the Screening juncture, additional hair is drawn from the original specimen and prepared for extraction. During this phase, drugs are extracted from hair at concentrations considerably lower than in other methods (such as urine or oral fluids), rendering hair drug screening the most challenging methodology.

Any positive outcome from the screening process is confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo washing before confirmation if required. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have the capability to disclose drug use for up to 90 days, surpassing the shorter detection window of urine tests.
• Hard to falsify: The difficulty in evading a hair drug test enhances result accuracy.
• Historical insight: It can reveal a pattern of drug consumption over time, not just recent use.

Limitations:

• Recent use detection: Drugs take about 5-7 days to become detectable in hair.
• Expense: Generally, hair drug tests incur a higher cost than other testing methods.
• Result variations: Variables like hair color and personal differences in hair growth may impact drug metabolite concentration in hair.

Note: Commonly referred to as "hair follicle tests", the analysis pertains to 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.
