Hair Follicle Drug Testing - Larose, LA

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. Hair retains a long-term record of alcohol and other drugs by embedding biomarkers within the fibers of the developing hair strand. When the hair is cut near the scalp, it can offer up to an estimated three-month detection timeframe for alcohol and other substances. The collection of hair is straightforward, moderately challenging to tamper with, and convenient to transport.

A 1.5-inch segment consisting of around 200 hair strands (approximately the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair, the optimal sample for analysis and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen weighing 150mg is advised. We suggest utilizing a jeweler’s scale for specimen weighing. If scalp hair is unavailable, an equivalent quantity of body hair can be obtained. When mentioning head hair, we exclusively refer to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).

Process Overview

The laboratory procedure for processing a drug test result consists of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary processing of a sample into a lab's system. This process verifies the sample was appropriately sealed and transported, assigns an arbitrary LAN (Laboratory Accessioning Number), and finalizes any supplemental data entry absent from an electronic chain of custody system.

Screening offers a preliminary rapid assessment for drugs of abuse. Although Screening provides a cost-efficient method to exclude drug usage for most samples, a positive result necessitates confirmation for legal admissibility. Samples with a presumptive positive outcome in Screening require a subsequent confirmation.

When a sample yields a presumptive positive in the Screening phase, additional hair is extracted from the original specimen for preparation in the Extraction phase. During this phase, drugs are isolated from hair at a significantly lower concentration compared to other methods (e.g., urine or saliva), making hair drug testing the most intricate methodology to perform.

Confirmation of any positive screening result is achieved via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing prior to confirmation as needed. The entire lab process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can determine drug use for as long as 90 days, as opposed to urine tests, which have a more limited detection period.
• Challenging to deceive: It is exceedingly challenging to falsify a hair drug test, thereby enhancing result accuracy.
• Offers historical data: This testing method can exhibit a pattern of drug consumption over time, not merely recent usage.

Limitations:

• Incapable of detecting recent use: It requires roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug testing is generally pricier compared to alternative drug testing methods.
• Result discrepancies: Factors like hair color and individual differences in hair growth might impact the concentration of drug metabolites in the hair.

Note: Though often termed "hair follicle tests," the test itself examines the hair strand rather than the follicle underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Larose, LA, hair follicle testing stands superior to more traditional urine tests due to their extensive detection capabilities.
