Hair Follicle Drug Testing - Hay Creek, MN

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying substance and alcohol consumption. Hair retains a prolonged history of substance use by capturing biomarkers within the matrix of the developing hair strand. When sourced near the scalp, hair offers an approximately 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

Taking a 1.5-inch section of roughly 200 hair strands (akin to the size of a #2 pencil) closest to the scalp yields 100mg of hair, which is the preferred sample size for analysis and confirmation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of hair is advisable. We suggest weighing the hair using a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair can be gathered. Head hair specifically denotes scalp hair. Meanwhile, body hair encompasses all other types (such as facial and axillary).

Process Overview

The laboratory analysis of a drug test result is broken down into four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial step of integrating the sample into a laboratory's system. This step involves ensuring the sample's seal and shipping were done correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data that isn't available through an electronic chain of custody system.

Screening performs an initial cursory examination for drug abuse. Although Screening is a cost-efficient practice to rule out drug use in most samples, any positive result requires confirmation to be considered valid in legal settings. Any samples tentatively testing positive in Screening need further confirmation.

If a sample registers as tentatively positive during Screening, more hair is extracted from the original sample for the Extraction phase. During Extraction, drugs are isolated from hair at notably lower concentrations than other testing methods (such as urine or oral fluid), which accounts for the complexity of hair drug analysis.

Verification of any positive Screening outcome utilizes GC/MS, GC/MS/MS, or LC/MS/MS. All samples returning presumptive positive results are cleansed as needed before confirmation. This comprehensive process from Accessioning to Confirmation undergoes evaluation under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection duration: Hair drug evaluations can identify drug use for up to 90 days, compared to urine tests which have a more limited detection period.
• Challenging to falsify: Hair drug tests are difficult to tamper with, thus ensuring more reliable outcomes.
• Supply of historical data: This method can outline a pattern of drug consumption over time, rather than just detecting immediate use.

Limitations:

• Inability to detect recent use: A timeframe of approximately 5-7 days is needed before drugs become identifiable in hair.
• Expense: Hair drug assessments typically cost more than other testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can influence drug metabolite concentrations in the hair.

Note: Commonly labeled as "hair follicle tests", the analysis targets the hair strand itself, not the hair follicle located 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.
