Hair Follicle Drug Testing - French, NM

What it is, How it works

Hair analysis has emerged as a robust technique for unveiling substance use, whether it be drugs or alcohol. Hair captures a prolonged substance history by entrapping biomarkers within the strands as they grow. When hairs are clipped near the scalp, they can offer insights into substance consumption for nearly three months. Hair is straightforward to gather, quite challenging to tamper with, and convenient for transport.

A 1.5-inch hair section, roughly 200 strands (about a #2 pencil's thickness) adjacent to the scalp, provides approximately 100mg, the ideal amount for testing. For EtG testing, additions, or tests exceeding 10 panels, 150mg is advised. Utilizing a jeweler's scale for weighing the hair is recommended. If head hair is unavailable, an equivalent amount of body hair can be used. Note that head hair refers specifically to hair on the scalp, while body hair includes other types such as facial or axillary hair.

Process Overview

The laboratory processing of drug test samples consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample undergoes its introduction to the laboratory's system. This phase ensures the sample's proper sealing and transport, assigns it a unique LAN (Laboratory Accessioning Number), and fills in any data not covered by an electronic chain of custody.

Screening offers a rapid assessment for drug presence. While it economically screens for drug use in the majority of cases, confirmation is imperative for court validity if the result is positive. Samples indicating a possible positive during Screening require subsequent confirmation.

In the event of a presumptive positive during Screening, additional hair is extracted from the primary specimen for the Extraction phase. Here, substances are separated from the hair at concentrations much lower than other methods (like urine or oral fluid), which adds to the complexity of hair drug testing.

Positive screening results undergo Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS techniques. Confirmatory testing requires prior washing of samples. Each step, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests have a detection period reaching up to 90 days, surpassing urine tests with shorter detection spans.
• Challenging to circumvent: Due to the difficulty in cheating, hair drug tests provide more reliable results.
• Chronological usage data: Hair testing reveals a pattern of substance use over time, unlike tests that detect only recent use.

Limitations:

• Recent use detection: Drugs typically become detectable in hair within 5-7 days post-use.
• Expense: Hair testing tends to incur higher costs compared to alternate testing methods.
• Result variability: Factors such as hair color and individual hair growth rates may influence drug metabolite concentrations within the hair.

Note: Commonly termed as "hair follicle tests", the analysis targets the hair shaft and not the follicle beneath the scalp.
