Hair Follicle Drug Testing - Tyaskin, MD

What it is, How it works

Hair screening has gained recognition as an effective resource for identifying drug and alcohol consumption. Hair offers an extended overview of substance use by capturing biomarkers within the fibers of the developing hair shaft. When obtained near the scalp, hair can reveal up to nearly three months of alcohol and drug usage history. Hair collection is straightforward, somewhat resistant to tampering, and simple to transport.

A 1.5-inch-length sample consisting of approximately 200 hair strands (comparable in diameter to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for analysis and verification. For EtG, extended panels, and/or tests exceeding 10 panels, a recommended 150mg of the sample is advised. We suggest measuring the sample on a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair might be gathered. References to head hair pertain solely to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

The primary steps in the laboratory handling of a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially processing a sample into a lab’s system. This includes ensuring the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input missing from an electronic chain of custody system.

Screening entails an initial rapid check for drugs of abuse. Screening is an economical means to exclude drug usage in most samples, but a positive screen must be verified to be admissible legally. Any samples that show a presumptive positive in Screening require further confirmation.

If a sample tests presumptively positive at the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. During this phase, drugs are isolated from hair at a much finer concentration than through other techniques (e.g., urine or oral fluid), rendering hair drug analysis the most challenging method to execute.

Verification of any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens undergo cleansing before confirmation if necessary. The comprehensive lab work from Accessioning to Confirmation is conducted in accordance with both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug exams can identify drug use extending up to 90 days, unlike urine tests with a shorter span of detection.
• Hard to deceive: It is notably challenging to falsify a hair drug test, ensuring greater accuracy of outcomes.
• Reveals historical usage: It can exhibit a pattern of substance use over time, surpassing only recent usage.

Limitations:

• Inability to detect recent ingestion: It generally takes 5-7 days for substances to be traceable in hair.
• Expense: Hair drug screenings typically incur higher costs compared to other drug testing methods.
• Result variability: Elements such as hair color and individual hair growth differences can impact the concentration of drug indicators within the hair.

Note: Despite commonly being termed "hair follicle tests", the analysis examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Tyaskin, MD, comparing hair follicle testing against traditional urine tests reveals a definitive advantage. Hair testing identifies drug usage over much longer periods, enhancing its accuracy and reliability. With urine tests covering a limited timeframe, hair analysis triumphs as the superior method sought by employers and professionals alike.

When it comes to detection, hair testing delivers high-fidelity insights that urine tests can't match. The broader detection window of hair testing provides a more comprehensive review, illustrating its indispensable role in contemporary substance screening.
