Hair Follicle Drug Testing - Darnell, LA

What it is, How it works

Hair assessments are now regarded as an effective means for identifying substance and alcohol consumption. Hair strands offer an extended timeline of substance use by capturing biomarkers within the fibers as hair grows. When trimmed close to the scalp, hair provides a detection period of roughly three months for alcohol and other substances. This method of collection is straightforward, reasonably resistant to tampering, and convenient for transport.

A sample measuring 1.5 inches with approximately 200 strands (akin to the thickness of a #2 pencil) near the scalp yields 100mg of hair, the preferred quantity for initial and confirmatory tests. For EtG, additional analyses, and/or screenings beyond 10 panels, 150mg is suggested. It's advisable to weigh the sample using a jeweler’s scale. Should scalp hair be inaccessible, a comparable quantity of body hair may be sourced. Mention of head hair specifically pertains to scalp hair, while body hair encompasses all other types (such as facial or axillary).

Process Overview

The primary stages in lab processing for a drug test outcome are Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the first-stage processing of a sample into the lab’s infrastructure. This stage includes ensuring the sample was properly sealed and transported, allocating a random LAN (Laboratory Accessioning Number), and completing any necessary data entry absent from an electronic chain of custody system.

Screening is a preliminary check for substance use. While being cost-efficient to exclude drug usage in numerous samples, any positive screen demands confirmation to be legally valid. Samples that test presumptively positive in Screening necessitate additional confirmation.

For samples testing presumptively positive in Screening, further hair is extracted from the original sample and readied for Extraction. This phase isolates drugs from hair at much lesser concentrations compared to other methods (e.g., urine or oral fluid), highlighting why hair screening demands significant proficiency.

Confirmation for any positive screen outcome is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. Each step from Accessioning through Confirmation is thoroughly reviewed under the oversight of the CAP (College of American Pathologists) Hair category and the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection timeline: Hair tests reveal substance use covering up to 90 days, unlike urine tests, which offer a shorter detection duration.
• Challenging to falsify: The difficulty in tricking a hair drug test enhances result accuracy.
• Historical record: It establishes a timeline of substance use over an extended timeframe, unlike recent use tests.

Limitations:

• Inability to detect recent consumption: Detecting substances in hair takes around 5-7 days post-consumption.
• Expense: Hair assessments typically cost more than alternative drug testing methods.
• Result variability: Factors like hair color and personal hair growth differences can impact drug metabolite concentration in hair.

Note: Although often called "hair follicle tests", the examination focuses on the hair strand, excluding the scalp's hair follicle.
