Hair Follicle Drug Testing - Gurley, LA

What it is, How it works

Hair testing is increasingly recognized as an effective method for uncovering drug and alcohol consumption. It provides an extended history of substance use by embedding biomarkers within the hair fibers as they grow. When collected close to the head, hair can indicate substance use within a detection timeframe of roughly three months. The process of collecting hair is straightforward, it's relatively challenging to tamper with the sample, and it can be easily mailed.

A sample of 1.5 inches containing around 200 hair strands (approximately the diameter of a #2 pencil) nearest to the scalp gives about 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, a specimen of 150mg is advised. The specimen should be weighed using a jeweler’s scale. In the absence of scalp hair, a comparable amount of body hair can be used. By head hair, we specifically mean scalp hair, while body hair encompasses all other types such as facial and axillary.

Process Overview

The laboratory processes for analyzing a drug test sample consist of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample is integrated into a lab's system. This process involves checking that the sample is properly sealed and sent, assigning it a random LAN (Laboratory Accessioning Number), and completing any required data entry not handled by an electronic chain of custody system.

Screening entails a preliminary evaluation for substances of abuse. Although cost-efficient for ruling out substance use in most samples, a positive screen necessitates confirmation for legal admissibility. Any sample that exhibits a presumptive positive result requires further confirmation.

For samples that show a presumptive positive in the Screening phase, additional hair is extracted from the initial specimen and processed for Extraction. This phase involves extracting substances from hair at significantly lower concentrations compared to other testing methods such as urine or oral fluid, highlighting the complexity of hair drug testing.

Confirmation of any positive screening outcome is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleaned before confirmation when necessary. The complete laboratory procedure, from Accessioning to Confirmation, follows review standards of both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify substance use for up to 90 days, unlike urine tests which have a shorter timeframe for detection.
• Difficult to manipulate: Cheating a hair drug test is extremely challenging, thus increasing the accuracy of the results.
• Tracks past usage: It offers a record of substance use patterns over time, rather than just recent usage.

Limitations:

• Cannot identify recent usage: It typically takes between 5-7 days for substances to become traceable in hair.
• Expense: Hair drug testing usually costs more than other drug testing methods.
• Result variability: Factors like hair color and personal differences in hair growth can influence the concentration of drug metabolites present in hair.

Note: Despite being commonly called "hair follicle tests," the actual test assesses the hair strand itself rather than the follicle beneath the scalp.
