Hair Follicle Drug Testing - Lake Lac La Belle, WI

What it is, How it works

Hair testing has emerged as a significant method for detecting alcohol and drug consumption. The hair fibers retain biomarkers across the growing strand, offering a longitudinal view of alcohol and drug history. When acquired near the scalp, hair can offer insight into drug and alcohol use for approximately three months prior. The collection of hair is straightforward, challenging to tamper with, and easy to transport.

A section of hair measuring 1.5 inches and consisting of roughly 200 strands (comparable to the thickness of a #2 pencil) from close to the scalp is needed to gather 100mg of hair, which is considered ideal for analysis and confirmation. For EtG evaluations, additional assessments, and tests with more than 10 panels, a recommended 150mg of the sample is necessary. Utilizing a jeweler’s scale for specimen measurement is advised. Should scalp hair be unavailable, an equivalent amount of body hair may be used. In discussing head hair, we specifically mean scalp hair. On the other hand, body hair includes all other hair types (facial, axillary, etc.).

Process Overview

Accessioning, Screening, Extraction, and Confirmation are the four pivotal steps in processing a drug test result at the laboratory level.

Accessioning is concerned with the preliminary incorporation of a sample into the laboratory framework. This encompasses verifying the proper sealing and shipping of the sample, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any additional data submissions absent from an electronic custody chain.

Screening executes an expedient preliminary analysis for drugs of abuse. Screening is a cost-efficient method to eliminate drug consumption for most samples; however, any positive screening results must be validated to hold in court. Samples that hint at positive results in Screening mandate subsequent confirmation.

If Screening suggests a positive result, additional hair is extracted from the primary specimen for the Extraction phase. During this procedure, hair releases drugs at notably lower concentrations compared to other techniques (example: urine or oral fluid), positioning hair drug screening as the most intricate methodology.

Confirmation of positive screenings is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positive outcomes are washed before confirmation, if necessary. The entire laboratory sequence, from Accessioning to Confirmation, is meticulously examined under both CAP (College of American Pathologists) Hair endorsement and completion to ISO / IEC 17025 criterion.

Advantages of hair drug testing:

• Extensive detection timeframe: Hair drug tests can identify drug consumption up to 90 days, in contrast to urine tests, which offer a shorter detection period.
• Challenging to falsify: Cheating a hair drug test is exceedingly difficult, ensuring increased accuracy of results.
• Delivers historical context: The test can illustrate a pattern over time of drug utilization, rather than just recent activity.

Limitations:

• Inability to identify recent activity: Drugs require about 5–7 days to manifest in hair.
• Expense: Hair drug tests are usually costlier compared to other drug testing techniques.
• Result variabilities: Variables like hair color and individual hair growth rates can influence drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests", the analysis is actually conducted on the hair strand rather than on the follicle beneath the scalp
