Hair Follicle Drug Testing - Chopin, LA

What it is, How it works

Hair analysis is now widely recognized as a highly effective means for identifying alcohol and drug consumption. Hair captures a comprehensive record of substance use by preserving biomarkers within the hair's growing fibers. When hair samples are taken close to the scalp, they can reveal drug and alcohol usage dating back up to roughly three months. Collecting hair samples is straightforward, relatively resistant to tampering, and convenient to transport.

A segment of hair measuring 1.5 inches, consisting of approximately 200 strands (comparable to a #2 pencil in thickness), from the area nearest to the scalp, yields 100mg of hair - the perfect quantity for screening and validation. For EtG, additional tests, and/or panels exceeding 10, a sample size of 150mg is advised. Utilizing a jeweler’s scale for weighing the hair sample is suggested. In the absence of scalp hair, an equivalent volume of body hair may be utilized. When mentioning head hair, it refers specifically to scalp hair. Body hair covers all other types (facial, axillary, etc.).

Process Overview

The drug testing procedure in a lab is comprised of four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary phase of integrating a sample into a laboratory’s system. It involves ensuring the sample was correctly sealed and shipped, assigning a Laboratory Accessioning Number (LAN) randomly, and completing any requisite data entry that an electronic chain of custody system does not provide.

Screening serves as an initial rapid assessment for substance abuse. Although Screening is an economical method for excluding drug use in most samples, any positive result from screening demands confirmation to be legally defensible. Samples that are presumed positive during Screening necessitate further confirmation.

When a sample yields a presumptively positive result at the Screening phase, additional hair is derived from the initial specimen, prepping it for Extraction. During Extraction, drugs are isolated from hair at a significantly lower concentration compared to other techniques (e.g., urine or oral fluid), proving hair drug analysis as a more challenging methodology.

Confirmation of positive Screening outcomes is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing before confirmation, as required. The comprehensive laboratory procedure from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can reveal drug usage for up to 90 days, whereas urine tests have a more limited timeframe.
• Minimal chance of tampering: Hair drug tests are highly resistant to cheating, resulting in more reliable outcomes.
• Gives historical insight: It can display patterns of drug consumption over time, not only recent use.

Limitations:

• Delayed detection of recent use: It usually takes around 5-7 days for substances to become detectable in hair.
• Expense: Compared to other drug testing techniques, hair drug tests are typically more costly.
• Result variability: Factors such as hair color and individual hair growth differences can impact drug metabolite levels in hair.

Note: Although sometimes called "hair follicle tests," the analysis targets the hair strand, excluding the follicle underneath the scalp.
