Hair Follicle Drug Testing - Glencoe, MN

What it is, How it works

Hair analysis has emerged as an effective means for detecting the consumption of drugs and alcohol. Hair captures a prolonged record of drug and alcohol usage by encapsulating biomarkers within the fibrous structure of the hair as it grows. When harvested near the scalp, hair offers an approximate 3-month timeframe for detecting drugs and alcohol. Hair collection is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch section comprising roughly 200 hair strands (similar in size to a #2 pencil) closest to the scalp will produce 100mg of hair, the optimal amount for both screening and confirmation purposes. For EtG, additional tests, or tests exceeding 10 panels, a sample of 150mg is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair isn't available, a comparable quantity of body hair may be gathered. In the context of head hair, we refer exclusively to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The four primary steps in the laboratory analysis for a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary inclusion of a sample into the laboratory's system. This procedure involves confirming that the sample is appropriately sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and performing any supplementary data entry not covered by an electronic chain of custody system.

Screening constitutes an initial rapid assessment for drug presence. While Screening is a cost-efficient method to exclude drug usage for most samples, a positive screening outcome requires confirmation for it to hold up in legal proceedings. Any samples that test presumptively positive during Screening need further verification.

If a sample shows a presumptive positive result during Screening, additional hair is extracted from the original sample and readied for Extraction. In this step, drugs are isolated from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), which is why hair drug screening stands as the most challenging method to execute.

Confirmation of any screening results indicating positive drugs is performed via GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptively positive specimen undergoes washing before confirmation as deemed necessary. The complete laboratory procedure from Accessioning through to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair designation and accreditation standards ISO / IEC 17025.

Benefits of hair drug testing:

• Extended detection window: Hair drug tests can identify drug usage for up to 90 days, a longer period than urine tests, which offer a shorter detection range.
• Hard to manipulate: It is exceedingly challenging to manipulate a hair drug test, which enhances the accuracy of the results.
• Offers historical insight: It can illustrate a pattern of drug usage over time, not merely recent consumption.

Drawbacks:

• Inability to determine recent use: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically more costly than other testing methods.
• Result variations: Factors such as hair pigmentation and individual differences in hair growth can influence the concentration of drug metabolites in the hair.

Note: While frequently called "hair follicle tests", the analysis focuses on the hair strand rather than 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.
