Hair Follicle Drug Testing - Glenwood, NE

What it is, How it works

Hair testing is increasingly seen as an effective means of identifying drug and alcohol consumption. Hair captures a historical record of substance use by encasing biomarkers within the strands of hair as they grow. If collected near the scalp, hair offers an approximately 3-month detection period for drug and alcohol use. The collection process is straightforward, tampering is relatively challenging, and the samples are easy to transport.

A sample consisting of 1.5 inches and approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp equates to around 100mg, which is optimal for screening and confirmation purposes. In cases requiring EtG, additional tests, or panels exceeding 10, a 150mg specimen is advisable. Using a jeweler’s scale for specimen weighing is recommended. If scalp hair is unavailable, an equivalent quantity of body hair may be used. When referring to head hair, it specifically means scalp hair, whereas body hair encompasses other types (like facial and axillary hair).

Process Overview

Laboratory processing of drug test results involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the stage of integrating a sample into the laboratory's system, ensuring the sample was securely sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing data entry not covered by electronic custody systems.

Screening conducts a preliminary assessment for substances of abuse. Though Screening serves as a cost-efficient method for excluding drug use in most samples, a positive screen must be validated for courtroom acceptance. Presumptively positive Screening samples necessitate further confirmation.

Should a sample test positive in Screening, additional hair is extracted from the original sample for Extraction. During Extraction, drugs are obtained from hair in significantly lower concentrations compared to methods like urine or oral fluid, highlighting the complexity of hair drug screening.

Confirmation of any positive Screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS technologies. Required washing of presumptive positive samples occurs before confirmation. The full laboratory workflow from Accessioning through Confirmation undergoes scrutiny under CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify up to 90 days of drug use versus shorter windows in urine tests.
• Hard to circumvent: Cheating a hair drug test is very difficult, rendering the results more reliable.
• Reveals usage history: It exhibits a timeline of drug consumption rather than only recent use.

Limitations:

• Limited recent-use detection: Drugs typically become apparent in hair after 5-7 days.
• Expense: Hair drug tests generally cost more than alternative methods.
• Result variability: Factors like hair color and personal hair growth differences can alter drug metabolite concentrations in hair.

Note: Though often called "hair follicle tests", the analysis is of the hair strand, not the hair 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.
