Hair Follicle Drug Testing - Wood Lake, MN

What it is, How it works

Hair evaluation has established itself as a robust mechanism for identifying drug and alcohol consumption. Hair captures drug biomarkers within its strands, offering an extended chronological timeline of substance use. When clipped near the scalp, this method extends the detection window up to 90 days for drugs and alcohol. Collecting hair is practical, less susceptible to tampering, and easily transportable.

A representative 1.5-inch hair sample, containing around 200 strands (roughly the circumference of a #2 pencil) located nearest the scalp, yields 100mg, which serves as an optimal sample for analysis and verification. For EtG, additional assays, or tests exceeding 10 panels, 150mg is advised. It's recommended to weigh this sample using a jeweler’s scale. Should scalp hair be unobtainable, an equivalent quantity of body hair may be gathered. "Head hair" denotes scalp hair specifically, whereas "body hair" applies to all other varieties (e.g., facial, axillary).

Process Overview

Drug testing in a laboratory encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into the laboratory system. This phase verifies proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data entry that isn’t covered by an electronic chain of custody system.

Screening undertakes a preliminary assessment for drugs of abuse. Though cost-effective for excluding drug use in the majority of instances, any positive screens require confirmation for court admissibility. Suspect positive samples from Screening need further confirmation.

A suspect positive in the Screening phase prompts additional hair extraction from the original sample for the Extraction phase. Here, drugs are isolated from hair at notably lower concentrations than in techniques like urine or oral fluid analysis, making hair drug testing exceptionally challenging to execute.

Verification of any initial positive screening is administered via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo pre-confirmation washing as necessary. The complete laboratory journey from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug assessments can reveal drug consumption for up to 90 days, unlike urine tests with shorter detection periods.
• Resistant to deception: Cheat attempts are notably arduous with hair drug assessments, boosting result credibility.
• Delivers historical insight: Reveals a pattern of drug activity over time, beyond immediate usage.

Limitations:

• Recent use is undetectable: Drugs may take roughly 5-7 days before becoming traceable in hair.
• Expense: Typically, hair drug tests are pricier than alternative testing methods.
• Result variability: Factors like hair pigment and personal growth rate can influence the concentration of drug metabolites within hair.

Note: Although colloquially referred to as "hair follicle tests", the analysis targets the hair strand, 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.
