Hair Follicle Drug Testing - Noble, LA

What it is, How it works

The utilization of hair testing has emerged as a robust approach for identifying drug and alcohol consumption. By embedding biomarkers in the fibers of the emerging hair strand, hair offers an extended-term record of alcohol and other drugs. When hair is sampled near the scalp, it can provide a detection period of up to three months for alcohol and other drugs. Hair collection is straightforward, relatively resistant to alteration, and easy to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp, sums up to 100mg of hair, representing the perfect specimen for screening and verification. When testing for EtG, add-ons, or above 10 panels, a 150mg specimen is advisable. Utilizing a jeweler’s scale for measuring the specimen is recommended. If scalp hair is not available, a similar quantity of body hair may be used. “Head hair” pertains to scalp hair exclusively, while “body hair” includes all other types (e.g., facial, axillary).

Process Overview

The laboratory process for determining a drug test outcome consists of four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning encompasses the initial incorporation of a sample into a lab's system. This phase includes confirming the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody system.

Screening encompasses an initial swift assessment for substance abuse. Although Screening is a cost-effective method for dismissing drug use in most samples, a confirmed positive is required for court admissibility. Samples with presumptive positives in Screening necessitate additional confirmation.

If a sample is deemed presumptively positive during the Screening phase, additional hair from the initial sample is prepared for Extraction. At this stage, substances are extracted from hair at considerably lower concentrations than other methodologies (like urine or oral fluid), establishing hair drug screening as the most challenging approach.

Confirming any positive Screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are cleansed as needed. The complete laboratory procedure, from Accessioning to Confirmation, is subject to review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditations.

Advantages of hair drug testing:

• Extensive detection period: Hair drug tests can uncover drug usage up to 90 days prior, contrasting with the shorter detection period of urine tests.
• Hard to manipulate: The difficulty in adulterating a hair drug test ensures more reliable results.
• Provides usage history: Hair drug tests can illustrate a pattern of drug usage over time, not just recent usage.

Limitations:

• Inability to detect recent usage: It takes approximately 5-7 days for drugs to appear in hair.
• Expense: Hair drug tests are usually more costly than alternative drug testing techniques.
• Result variations: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: While colloquially termed "hair follicle tests", the analysis targets the hair strand, not the follicle underneath the scalp.
