Hair Follicle Drug Testing - Central City, AR

What it is, How it works

Hair testing has gained recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a chronological record of alcohol and drug use by capturing biomarkers within the structure of the hair as it grows. When taken near the scalp, hair can offer a detection window of up to three months for alcohol and various drugs. Hair collection is straightforward, hard to tamper with, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (similar in size to a #2 pencil) closest to the scalp yields 100mg of hair, which is the optimal sample for analysis and verification. For EtG, additional tests, and/or panels beyond 10, specimens of 150mg are advised. It's recommended to weigh the sample with a jeweler’s scale. If scalp hair can't be obtained, a comparable quantity of body hair can be used. When discussing head hair, it pertains strictly to scalp hair. Body hair covers all other types (facial, axillary, etc.).

Process Overview

The key stages in laboratory processing of test outcomes are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary phase of lab integration of a sample. This step comprises verifying the sample's seal and proper shipment, assigning a LAN (Laboratory Accessioning Number) randomly, and finalizing any supplemental information not captured by a digital custody chain system.

Screening entails a preliminary assessment for drugs. Although Screening offers a budget-friendly approach to discard drug use in most samples, a positive result must be verified for court acceptability. Presumptively positive samples in Screening undergo secondary verification.

If Screening indicates presumptive positivity, additional hair is taken from the original sample for Extraction. In Extraction, drugs are separated from hair at concentrations far lower than those found in other methods (e.g., urine or oral fluid), making hair drug testing the most challenging to conduct.

The verification of positive screenings uses GC/MS, GC/MS/MS or LC/MS/MS techniques. All presumptive positive samples undergo washing before verification as required. The end-to-end lab process, from Accessioning through Confirmation, complies with both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair tests reveal drug use for up to 90 days, unlike urine tests which show a shorter period.
• Low probability of deception: Cheating on a hair test is highly unlikely, ensuring result precision.
• Historical usage pattern: It reflects extended drug use patterns over time, beyond recent consumption.

Limitations:

• Inability to identify recent use: Detection of drugs in hair takes roughly 5-7 days.
• Expense: Hair testing often costs more than alternative testing techniques.
• Result inconsistencies: Variables like hair color and individual hair growth differences can influence drug metabolite levels in hair.

Note: Although sometimes called "hair follicle tests", the procedure examines the hair strand, not the underlying hair follicle.

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.
