Hair Follicle Drug Testing - Laurel Grove, LA

What it is, How it works

Hair analysis is increasingly acknowledged as a potent means for identifying drug and alcohol intake. Hair retains a comprehensive record of alcohol and other substances by embedding biomarkers within the strands as they grow. When taken from the area nearest to the scalp, hair offers an approximate detection period of three months for alcohol and drug analysis. The simplicity of collecting hair, its resistance to tampering, and the ease with which it can be shipped all add to its benefits.

A sample measuring 1.5 inches, consisting of around 200 hair strands (roughly the diameter of a #2 pencil) closest to the scalp, yields 100mg of hair, which is perfect for both screening and confirmation. For EtG, additional analysis, or tests exceeding 10 panels, a sample of 150mg is advised. It is best to weigh the specimen using a jeweler’s scale. In the absence of scalp hair, an equivalent measure of body hair is sufficient. When discussing head hair, we specify scalp hair. Body hair includes other types such as facial or axillary hair.

Process Overview

There are four primary stages in processing a drug test in the lab: Accessioning, Screening, Extraction, and Confirmation.

Accessioning initiates the sample's integration into the lab system. This step confirms that the sample was properly sealed and transported, assigns a unique LAN (Laboratory Accessioning Number), and completes any missing data not available from an electronic chain of custody.

The Screening phase is a preliminary, rapid assessment for substances of misuse. Although Screening is economical for excluding the majority of samples, a positive indication requires Confirmation for legal validity. Samples that are initially positive in Screening undergo further confirmation.

In cases where Screening suggests positivity, more hair is sourced from the original sample for Extraction. This phase involves isolating drugs from hair at concentrations lower than those found in other methods, such as urine or saliva tests, underscoring the complexity of hair drug analysis.

GC/MS, GC/MS/MS, or LC/MS/MS methods confirm any positive Screening outcomes. All samples with presumed positivity undergo pre-confirmation washing as necessary. From Accessioning to Confirmation, the process is scrutinized according to both CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeframe: Hair testing can trace drug usage for up to 90 days, unlike urine tests with shorter periods.
• Hard to manipulate: The robust nature of hair drug testing reduces the chances of manipulation, resulting in reliable outcomes.
• Historical insight: It tracks drug usage patterns over time, rather than solely detecting recent activity.

Limitations:

• Delayed detection for recent use: Substances become noticeable in hair roughly 5-7 days post-usage.
• Expense: Hair drug evaluations typically incur higher costs than other testing approaches.
• Result variation: Aspects like hair color and individual differences in hair development can alter metabolite concentrations.

Note: Although commonly termed as "hair follicle tests", these analyses focus on the hair strand itself, not the follicle beneath the scalp.
