Hair Follicle Drug Testing - Lafourche Crossing, LA

What it is, How it works

Utilizing hair analysis has become recognized as an effective means for detecting drug and alcohol consumption. Hair strands incorporate biomarkers in their fibers, providing a comprehensive history of alcohol and drug use over an extended period. When procuring hair close to the scalp, it offers approximately a 3-month timeframe for detecting substances like alcohol and drugs. Hair collection is straightforward, hard to tamper with, and convenient for shipping.

A 1.5-inch sample consisting of roughly 200 hair strands (approximating the girth of a #2 pencil) is necessary to yield 100mg of hair, which is ideal for both screening and confirmation purposes. For EtG screenings, additional tests, and examinations extending beyond 10 panels, a suggested 150mg of the specimen should be acquired. It is advisable to weigh the hair specimen using a jeweler’s scale. In situations where scalp hair cannot be obtained, an equivalent quantity of body hair is acceptable. References to head hair pertain solely to scalp hair, while body hair includes other types like facial and axillary hair.

Process Overview

The laboratory processing of a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning starts with incorporating a sample into a lab's database. It entails verifying correct sealing and shipping of the sample, allocating a random Laboratory Accessioning Number (LAN), and completing additional data entry not facilitated by an electronic chain of custody setup.

Screening serves as an initial, cost-effective examination for drugs of abuse. This stage helps in quickly dismissing drug usage on numerous samples. However, a positive result from the Screening phase necessitates a confirmation for legal admissibility. Any samples indicating presumptive positivity in this phase require further confirmation.

In the event of a presumptively positive screen, additional hair from the original specimen is used in the Extraction stage. Drugs are extracted from hair in lower concentrations than other methodologies such as urine or oral fluid, making hair drug screening one of the most complex to execute.

Confirmation of any positive screening results is conducted using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory workflow, from Accessioning to Confirmation, adheres to the CAP (College of American Pathologists) Hair designation and accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Hair tests can identify drug use for up to 90 days, exceeding the shorter window of urine tests.
• Challenging to manipulate: Due to its rigorous nature, hair drug testing yields highly accurate results.
• Historical insight: Provides insight into drug use trends over time, not limited to recent consumption.

Limitations:

• Recent use detection: Drugs typically become detectable in hair approximately 5-7 days post-consumption.
• Higher cost: Hair drug testing incurs more expense than alternative testing methods.
• Result variations: The concentration of drug metabolites in hair may vary due to factors like hair color and growth rate.

Note: Although it is often labeled as a "hair follicle test," the examination targets the hair strand and not the follicle beneath the scalp.
