Hair Follicle Drug Testing - Flag, AR

What it is, How it works

Hair analysis has emerged as a robust method for detecting drug and alcohol consumption. Hair captures a historical record of substances by embedding biomarkers in its fibers as it grows. When taken near the scalp, it offers up to a 3-month window for detecting alcohol and drugs. Collecting hair is straightforward, tough to tamper with, and easy to ship.

A sample measuring 1.5 inches with around 200 hair strands (comparable to a #2 pencil) closest to the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg is suggested. We advocate weighing the sample using a jeweler’s scale. If scalp hair is unavailable, a similar quantity of body hair may be used. By head hair, we mean scalp hair only. Body hair includes all other types (like facial or axillary).

Process Overview

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

During Accessioning, samples are initially processed in a laboratory system, ensuring they are properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any data entry not covered by an electronic chain of custody system.

Screening consists of a preliminary quick review for drugs of abuse. Although Screening is cost-efficient for ruling out drug usage in most samples, a positive result needs confirmation to be valid in court. Presumptive positives in Screening require further confirmation.

If a sample is presumptively positive, additional hair is extracted from the original specimen for the Extraction stage. Here, drugs are isolated from hair at much lower concentrations than other methods (like urine or oral fluid), making hair drug testing the most challenging to execute.

Confirmation of any positive Screening result uses GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing prior to confirmation if necessary. The entire lab process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Long detection window: Hair drug tests detect drug use for up to 90 days, while urine tests offer a shorter window.
• Hard to manipulate: Cheating a hair drug test is highly challenging, enhancing accuracy.
• Chronological data: Offers a timeline of drug usage over an extended period, not merely current use.

Limitations:

• Cannot detect recent use: Drugs become detectable in hair within approximately 5-7 days.
• Expense: Hair tests are generally pricier than other drug testing techniques.
• Result variability: Factors like hair color and personal differences in growth can influence drug metabolite levels in hair.

Note: Although often termed "hair follicle tests", the analysis involves the hair strand, not the follicle beneath the scalp.
