Hair Follicle Drug Testing - Cooksville, WI

What it is, How it works

The analysis of hair has emerged as an influential medium for identifying the presence of drugs and alcohol. Hair captures an extended history of substance consumption by embedding biomarkers within the strands as they grow. When sampled near the scalp, hair can offer a detection period spanning up to three months for both alcohol and drugs. The collection process is straightforward, alteration is relatively challenging, and the shipment is uncomplicated.

A sample measuring 1.5 inches, consisting of about 200 hair strands (similar in diameter to a #2 pencil) closest to the scalp, yields 100mg of hair—ideal for both screening and confirmation. For tests including EtG, additional analyses, or those surpassing 10 panels, a specimen mass of 150mg is preferable. We advocate for the use of a jeweler’s scale for precise measurement. In the absence of scalp hair, an equivalent amount of hair from the body can be utilized. "Head hair" specifically pertains to scalp hair, while "body hair" encompasses other forms such as facial or underarm hair.

Process Overview

The laboratory processing of a drug test result involves four principal steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning signifies the initial incorporation of a sample into the laboratory's system. This covers the verification of intact and correctly dispatched samples, the allocation of a unique LAN (Laboratory Accessioning Number), and the completion of any unprovided data that doesn't come through an electronic chain of custody.

Screening conducts an initial quick scan to spot substances of abuse. Though cost-effective, a positive screen necessitates confirmation to stand as valid evidence in legal matters. Samples that register as presumptively positive via Screening require further confirmation.

If a sample tests positive during Screening, additional hair from the original collection is used for Extraction. In this stage, drugs are isolated from hair at notably lower concentrations compared to other methods like urine or oral fluid; hence, hair drug analysis presents considerable complexity.

Confirmation of positive screening outcomes is performed using either GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positives are cleansed before confirmation if required. The complete laboratory operation, from Accessioning through to Confirmation, is subject to scrutiny under the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair tests can uncover drug usage for up to 90 days, unlike urine tests that offer a narrower window.
• High difficulty to compromise: The formidable challenge of deceiving a hair test lends to more accurate results.
• Yields historical insights: It reveals usage trends over time, rather than merely recent consumption.

Limitations:

• Non-detectable for recent use: Drugs take about 5-7 days to manifest in hair.
• Expense: Hair drug analysis generally incurs higher costs compared to other testing techniques.
• Result variability: Elements like hair color and personal hair growth rates can influence drug metabolite concentrations in hair.

Note: Although often labeled as "hair follicle tests", the evaluation targets 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.
