Hair Follicle Drug Testing - Deale, MD

What it is, How it works

Hair analysis has emerged as a robust method for uncovering alcohol and narcotic consumption. By embedding biomarkers within the structures of hair, it reveals an extended history of substance intake. When hair is taken near the scalp, it can present a detection timeframe of up to around three months for substances and alcohol. Hair collection is straightforward, relatively tamper-proof, and convenient for transport.

An ideal screening and verification sample consists of a 1.5-inch segment containing roughly 200 hairs (similar in thickness to a #2 pencil) near the scalp, amounting to 100mg of hair. For EtG, add-on, and/or over 10-panel tests, a recommendation of 150mg of hair exists. It's advisable to measure the hair using a jeweler's scale. When scalp hair is not accessible, the collection of an equivalent mass of body hair is possible. "Head hair" pertains specifically to scalp hair, whereas "body hair" covers all other types (facial, axillary, etc.).

Process Overview

Drug test laboratory processing comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves integrating a sample into a lab's system. It includes confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and filling in any further required data not provided electronically.

Screening performs an initial cursory evaluation for substance abuse. This cost-efficient procedure serves to exclude drug exposure in most samples, but a positive result demands confirmation for validity in legal contexts. Samples initially positive during Screening necessitate additional validation.

A presumptive positive outcome in the Screening phase leads to additional hair being extracted from the primary sample for the Extraction phase. Drugs are then isolated from hair at lower levels than other methods (e.g., urine or saliva), contributing to the complexity of hair-based drug analysis.

Confirmation of any positive findings during screening employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Necessary washing of all samples deemed presumptive positive occurs before confirmation. The comprehensive process, from Accessioning through Confirmation, is examined under the CAP (College of American Pathologists) Hair classification and accrediting to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests identify substance usage for up to 90 days, in contrast to the reduced window of urine tests.
• Challenging to falsify: Its inherent difficulty in falsification enhances result accuracy.
• Offers historical insights: It demonstrates drug usage patterns over time, rather than merely recent consumption.

Limitations:

• Incapable of detecting recent consumption: Drugs become traceable in hair approximately 5-7 days post-use.
• Expense: Hair drug tests typically entail greater costs than other testing protocols.
• Result variability: Drug metabolite concentration can be influenced by factors including hair color and individual hair growth disparities.

Note: While termed as "hair follicle tests," the examination focuses on the hair strand, not the follicle beneath the scalp.
