Hair Follicle Drug Testing - Mcleod, MT

What it is, How it works

Hair analysis is increasingly regarded as an effective method for detecting drug and alcohol usage. Hair records a prolonged history of alcohol consumption and drug use by embedding biomarkers within the strands as they grow. When gathered near the scalp, hair offers an approximate 3-month window to detect alcohol and drug presence. Collecting hair is straightforward, relatively tamper-proof, and easy to transport.

An ideal sample for assessment and verification comprises a 1.5-inch segment of around 200 hair strands (approximating the dimension of a #2 pencil) nearest to the scalp, equating to 100mg of hair. For tests involving EtG, additional factors, or more than 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair is inaccessible, an equivalent volume of body hair can be used. References to head hair denote scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The core steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes initial processing within a laboratory’s system. This phase ensures the sample's proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and records any additional data not covered by an electronic chain of custody.

Screening conducts a preliminary evaluation for abuse drugs. Although a cost-effective approach to eliminate drug use in most samples, a positive screen requires confirmation to be legally valid. Samples deemed presumptively positive in Screening need further confirmation.

When a sample tests presumptively positive at the Screening stage, additional hair is sourced from the original specimen for Extraction. During Extraction, drugs are extracted from the hair at a much reduced concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening a challenging technique to perform.

GC/MS, GC/MS/MS, or LC/MS/MS is utilized to confirm any positive screening results. Presumptive positive samples undergo a wash prior to confirmation as necessary. The entire process from Accessioning to Confirmation is reviewed under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use for up to 90 days, unlike urine tests with a shorter detection timeframe.
• Hard to manipulate: Tampering with a hair drug test is highly challenging, ensuring more accurate results.
• Offers historical insight: Provides a drug use pattern over time, not just recent consumption.

Limitations:

• Inability to detect recent usage: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests tend to be pricier than other testing methodologies.
• Result variability: Variables such as hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
