Hair Follicle Drug Testing - Leader, MN

What it is, How it works

Hair analyses have grown to be regarded as an effective instrument for uncovering drug and alcohol consumption. Hair offers an extended chronicle of alcohol and other substances by capturing biomarkers in the fibers of the hair shaft as it develops. When obtained near the scalp, hair can present up to a roughly 3-month detection duration for alcohol and other substances. Hair is straightforward to gather, moderately challenging to tamper with, and conveniently transportable.

A 1.5-inch specimen comprising approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will provide 100mg of hair, the optimal sample size for testing and confirmation. For EtG, supplementary analyses, and/or evaluations above 10 panels, 150mg of the sample is advised. We propose weighing the sample on a jeweler's scale. If scalp hair is not accessible, an equivalent quantity of body hair may be used. When we mention head hair, we specifically mean scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).

Process Overview

The four principal phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning comprises the initial processing of a sample into the lab’s framework. This entails confirming that the sample was sealed and dispatched correctly, assigning an arbitrary LAN (Laboratory Accessioning Number), and performing any further data entry absent in an electronic chain of custody system.

Screening constitutes a preliminary rapid examination for drugs of abuse. While Screening is an economical means to dismiss drug usage in the majority of samples, a positive screen must be corroborated to be permissible in court. Any samples that are initially positive during Screening require a further validation.

If a sample exhibits presumptive positivity in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During this phase, drugs are isolated from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), which is why hair drug screening is the hardest method to execute.

Validation of any positive screening outcome is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before validation as necessary. The comprehensive lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the accreditation according to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests are capable of detecting drug use for up to 90 days, unlike urine tests which have a reduced detection span.
• Complexity to deceive: It is highly challenging to circumvent a hair drug test, enhancing the accuracy of results.
• Offers historical insights: It provides a utilization pattern over a timeframe, not merely recent use.

Limitations:

• Inability to detect recent consumption: Approximately 5-7 days are needed for drugs to manifest in hair.
• Expense: Hair drug assays are typically pricier than other drug testing approaches.
• Variability in outcomes: Factors such as hair color and personal hair growth variations can influence the concentration of drug metabolites in the hair.

Note: Although frequently termed "hair follicle tests", the analysis examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

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.
